This issue does not reproduce with dev preview 4.

Closing this issue as per comment #2 from reporter.

I have the same issue  I am receiving 2-6mbs wifi link speeds. Unacceptable

The new 4.2.1 update seems to have solved my slow Wi-Fi issue.

To add to this: The update did not fix the wifi issue on my device. On the wireless-g I get a 6mbps connection and on wireless-n I get about 64mbps. I have confirmed these low speeds at my server end too i.e. it is not the Nexus 4 reporting the speeds incorrectly.

I have a Nexus 4 running 4.2.1 and am having WiFi speed issues.  If I turn WiFi off then back on again then it resolves the problem for a period of time.  When the problem occurs I get 2MB down/9MB up, when it's working I get 40M down/10MB up.

I changed the wifi channel on my router, seems to have done the trich gettin around 58-65mbs wifi speeds on the n4, also updated to 4.2.1

Same with my Nexus 4. It has got 4.2.1 update but wifi speed is very slow. Other devices has perfect speed

Changing the channel makes no difference for me this issue seems to happen when the phone goes into deep sleep. I've tried changing the optimisation setting to no avail.

Same here... wifi is TERRIBLY slow and I get random disconnects when I have full signal...?

I too suffers the same problem.  Tried most things that users are logging:
1) reconnects... failed
2) 2.4ghz only... failed
3) Disable Data and enable 2g (I know this is unrelated but I tried anyways)... failed

Slow WiFi speed to a point I get timed out by Google Play Store

Also having this issue.

Disabling and re-enabling restores Wi-Fi to full speed, after a while speeds are dismally slow again.

I am see the same issue with 4.2.1 as well. It works fine some times and other it is dismally slow even while it reports a strong signal.

I am having the same issue with wifi on the Nexus 4.  I am practically sitting right next to wifi router and the slowless is frustrating.  Even the google play store times out on the connection all this while Nexus 4's wifi showing a excellent signal quality with link speed of 54 Mbps.  I've tried wifi speeds on two different networks with same outcome.  All this while, my other devices on the network are working fine even the Nexus 7.

I am talking to Support to return the device.

I'm also having very slow download speeds when on WiFi at home. I've torn down and rebuilt my home network multiple times and have had zero success at making download speeds on the phone any better. Neither my Nexus 7, nor my Galaxy Nexus have any such issues.

Mine also has the issue with a constant popping/crackling sound in the earpiece, so I've ordered a replacement from Google that's supposed to arrive next week. Hopefully it will not have these same issues.

It's the GPS.  If I leave the GPS off then the issue goes away and my phone maintains fast Wi-Fi speeds.  If the GPS enabled then the problem occurs after using any app that uses GPS (Speed Test itself for example).

I can reproduce this every time:

1. Disable GPS and reconnect to your WLAN.
2. Fire up the Speed Test app and run a test.  Fast!
3. Leaving Speed Test running go into settings and enable GPS.
4. Switch back to Speed Test and hit Restart Test. SLOW!

Once the connection speed drops it will stay like this even if GPS is disabled again and only reconnecting to the WLAN clears it.

I've had GPS disabled all the time and the Wi-Fi download speed is unacceptably slow with Play store timing out all the time. I added the N4's MAC address to the router settings, it didn't help. Switching from Auto band to 2.4 only or 5 only didn't help either. Disabling wi-fi optimization didn't help.

Yeah, I keep GPS disabled as well, so it seems unlikely that it would be the culprit for my slow WiFi download speeds as well. Not to mention that the Speedtest app really isn't a good way to test this particular problem (on my phone anyway). Even when I'm getting good/typical test results from using the Speedtest app, my download speeds from the Play Store are abysmal. That's been the real way to test this issue on my phone: downloading stuff from the Play Store.

I'm really thinking my phone has faulty WiFi hardware in it. I restarted my phone last night and when it came back up my Play Store download speeds were what they should be: nice and fast. I was getting multiple Megabytes/second while on my home WiFi while downloading apps from the Play Store. And this is only the 3rd time it's managed to behave properly in this regard since I first received the phone (which was from the very first round shipped out from Google).

So since it was surprisingly working properly, I started opening apps to see if any of them would cause my Play Store download speeds to drop, but none of them did.

I also tried enabling and disabling GPS and it didn't seem to make any difference in this regard either.

I then rebooted the phone and did some more Play Store tests and that was when it went back to crappy speeds. After the reboot, it was painfully slow again.

So with flakey behavior like this, it wouldn't surprise me if my phone does indeed have faulty hardware.

I have not tried disabling the GPS, however I would also like to report that not only is my Nexus 4's wifi incredibly slow (on the order of dial-up networking, and frequently causes transfers to time out) it also appears to be negatively affecting other nearby devices on the same AP.

I received my Nexus 4 and Nexus 10 on the same day, and while both were connected to wifi, neither was able to successfully transfer anything. After disabling wifi on the 4, the 10 started to work again.

I am suffering slow WiFi aswel. Only way to get back up to speed is to turn WiFi off then back on on my nexus 4. What is being done to address this problem???

Issue has been raised. Refer to Issue 36949180: Nexus 4 and Nexus 7 Wifi Drops connection Android 4.

Also having this issue. Only way is to turn WiFi off and then on.

Just got my nexus 4 and I do have extremely slow WiFi speed as well.
Turning off GPS didn't solve the problem.
PS. Upgraded to the latest version of android

Just got the device, very disappointed. Not sure if it is a hardware or software issue, also running latest android - 4.2.1. First thought it was my broadband but realised it was the device, if it is hardware who/where do I go to for a replacement or at least a refund.

P.S I'm in the UK. Typed this on Nexus 10 which works in terms of WiFi

Same issue here with a brand new Nexus 4.  I need to know if this is a hardware or software issue too.  I've tried just about everything imaginable and am certain the problem is with the device. It seems that in airplane mode with WiFi only enabled, the slowdown does not occur.  I noticed that when you turn the cellular radios back on after being in airplane mode, the slowdown returns.  This is just ridiculous that something as fundamental as properly functioning wifi, needs to be such a hopeless hassle.  Very frustrated...

Same issue, very slow wifi tried different wifi channels and freq bands made no difference. Took it back to the shop got a replacement which annoyingly was working fine in the shop but as soon as i got home realised that i got the same problem even tried other routers still same problem not sure what to do now...

Try and enable airplane mode, with only the wifi enabled.  When doing so, I am not getting the excessive wireless slow down.  If you can live with a wifi only phone for a couple hours, please test.  It's almost as if when the cell radios turn on, the wifi slowness immediately follows.  By the way, I only have G (1G) service at my house.  Could it be that the phone cant handle wifi/G at the same time?  I'm going to try and test in an environment where I have hspa/3g and see if I can still get the wifi to become lethargic when enabling the 3g/hspa radios.  I hope this issue gets fixed, and soon!

I'm going to suspect that the problem with slow WiFi performance is related to TCP window scaling.  I have an old Cisco router as my gateway Internet router, and it doesn't properly support TCP window scaling.  As such, I have to disable TCP window scaling on all of my Windows Vista/7 computers.  This is done from the netsh prompt and type "interface tcp set global autotuninglevel=off" or something like that.  Google is your friend to find the exact command.  I suspect that if I could modify a sysctl property of the Linux kernel used by Android, that I could resolve the WiFi speed problem.  This page explains how to disable TCP window scaling on Linux. [ http://www.ecr6.ohio-state.edu/window-scaling.html ] So how can I get a shell on Android?

Try a terminal emulator app from the Play Store.

A terminal emulator app is unlikely to work as root access is required to modify sysctl.  Perhaps this is a good place to start: http://www.droidxforums.com/forum/droid-x-hacks/19145-tutorial-roms-sysctl-conf-other-tweaks.html

Thanks for keeping this thread going.  My router is a brand new Asus Rtac66u Dark Knight, with the latest firmware.  The WiFi runs at full speed for let's say 30 minutes, and then slows way down until you turn the phones WiFi off, then back on.  When its running fine I get a constant 25megabits from my Comcast hookup.  When my Nexus 4 goes into the flaky/slow mode, it maxes at a constant 2.2 megabits per second until the WiFi is cycled off/on. Then after a while, the slowdown occurs again and again.  No other devices have these issues.

Perhaps this one step root kit will provide me with access to modify the sysctl values: http://www.xda-developers.com/android/extremely-awesome-google-nexus-7-all-in-one-toolkit/

@MikeyJen I highly doubt your router does not support TCP window scaling so what I'm babbling about won't impact you.  Sorry.

I've also found that toggling Aeroplane Mode on/off will cure my slow wifi issue for a period of time.  I can leave everything on - GPS, NFC, etc. and wifi is fine.  I then turn the screen on my phone off for a while and then the problem reappears.  It's very frustrating.  I wonder if leaving the cell radio on can somehow confuse the wifi network settings when the device sleeps?

I am also having issues with Wifi.  I have to keep turning off the wifi and using cell signal to do any downloading or browsing.  I thought that not having LTE would not be an issue but not if I can't use WIFI.

I have a dual band WNDR 3700 Netgear router capable of 300 Mbps transfer speeds, and I found that if I use WPA-PSK [TKIP] instead of WPA2-PSK [AES] my speeds are normal.  This requires me to drop down to 54 Mbps transfer speeds, but i still get decent DL speeds from the play store.  If i leave it at 54 Mbps and then change the encryption to WPA2, it starts to slow way down again.  I also noticed when going to the testing page from dialing *#*#4636#*#* that TKIP was mentioned in one of the WI-FI fields which lead me to try this experiment.  I don't think it matters if its on 2.4 or 5 Ghz.  So maybe its just due to lack of proper AES or WPA2 support?  Sorry if this is wrong, I'm not really a techie, I just like to experiment on stuff that annoys me.

I just got my Nexus 4 yesterday, and I am also seeing slow WiFi speeds.  I have a Asus RT-N66U router, capable of up to 900 Mbps, my SGS3 would show 300 Mbps on 5 Ghz, but this Nexus 4 only shows 58-72.

I got my nexus 4 yesterday. When i turned it on it auto update it to android 4.2.1. Im having wifi problems also i cant get it to hold a connection for more than 10seconds.

This is my second Nexus 4 as the first one had the horrible popping/hissing and cracking in the earpiece. This new phone now has HORRIBLE wifi speeds. Same as described by the others here. I really don't want to get a THIRD Nexus 4 but 2 mbps on a 30 mbps Internet is unacceptable. I really really hope this is a software issues and can be fixed with an update. If not I'd better send in for a third replacement.

I got my Nexus 4 on 12/12/12, and it auto-updated to 4.2.1 after which the Wi-Fi speed on my home network dropped to the levels others here describe, with other devices on the network behaving as normal.  At my work (WPA2 Enterprise) the speed was as expected, so I realised it was my wi-fi and not the phone quite quickly. I switched off Wi-Fi Optimisation and at first all seemed well, but soon the speed dropped dramatically again.  After reading the comments here I decided to try to make some changes on the router.  My router was supplied by the ISP, Virgin Media (In the UK) and is a D-Link D615d4, which is specific I think to Virgin, but I had flashed it with DD-WRT.  I checked to see if there had been an update to DD-WRT since I had originally flashed it.  There is, so I did the update and since then (24 hours so far) I have not seen the speed drop again.  I'm not counting my chickens yet, but I will keep my fingers crossed and hopefully my description will help others.

the nexus 4 seems to have more problems when connecting though a d-link wifi point

Have a Nexus 4 and Nexus 7. Both devices are averaging roughly 600kbps via speed test.

Have the same issue with nexus 4.
Advice from comment #39 helps for 1 minute after re-connecting.
After 1 minute speed degrades to zeros.
Router is D-Link.

D-Link router here, wifi is pretty much unusable for anything - remains connected with good signal, but data just times out.

Other devices work fine, Nexus 4 worked fine on a different wifi network - just this combo seems bad.

Upgrading dd-wrt to the latest build on my D-Link 615 D2 solved the problem for me, out has been fine for 4 days now.

After reading the above post stating that a D-Link router with the DD-WRT firmware fixed the slow WiFi speed issue for another user, I went and bought an ASUS RT-N10+ (rev. B1) router that is compatible with the DD-WRT firmware and planned to try it out tonight with my Nexus 4.

I setup the ASUS router a little earlier this evening and decided to just go ahead and try it as it was, out of the box, with my Nexus 4 and it worked just fine! Right off bat I was getting download speeds of 2-5 MB/s in the Play Store, whereas before I would only get 200-500 KB/s.

I'm going to test it out over a few more days and make sure it continues to work properly but it would seem there is something that the Nexus 4 just does NOT like about my other 2 routers. (One router is the Verizon HomeFusion router that Verizon supplies for their LTE-based HomeFusion service and the other router is an Apple Airport Extreme).

Absolutely aggravating that this issue has only ever happend with the Nexus 4 phone (and 2 different ones at that). All the other cell phones and tablets I've used at home (and there have been LOTS) have never had this issue! And that includes my Nexus 7, Galaxy Nexus (both GSM and LTE models) and my Motorola XOOM.

My router is also a D-Link (DSL-2780 free from TalkTalk) and I am having similar wifi issues.  I used wifi tethering to my other phone and the nexus 4 was fine using the other phone's H+ connection so I also believe this is an issue specific between Nexus 4 and D-Link routers.  I will be testing the Nexus 4 on another router to see if it is OK and if so may look at getting another non D-Link router.  I tried updating the firmware of this router and if anything the wifi has become more flakey for my other devices - takes longer to connect etc.

Alright, so I found a possible solution to this from XDA, here http://forum.xda-developers.com/showthread.php?t=1783175&page=6. Pry open the back cover with your fingernail (iFixIt has a guide, don't worry about the warranty, there is no seal and it snaps right back in). Inside the back cover there will be multiple copper pieces labeled Wifi, GPS, NFC. This shows you which prongs on the device correspond to which function. The Wifi prongs are on the top right of the device, near the microphone hole.

Bend. Them. Up.
Slightly.

This will give them better contact with the backplate and theoretically better signal. I can now browse the web at humane speeds but I will still send this back for warranty after the holidays.

I had issues with extremely slow Wifi on my Nexus 4. However, switching from my N to A/B/G network solved that issue for me. Not sure if the issue is related to the N4 or my D-Link router..

Having slow wifi here as well on my nexus 4. DD-WRT v24-sp2 firmware for router. It doesnt disconnect, just too slow internet up to a point that pages no longer load.

Hi guys
I am in UK and have broadband supplied by Sky. My WiFi is dead slow on my nexus4, slower than my mobile network. I have no idea about some of the technical terms being used. Can someone help. ( I have not contacted Google yet)

I am on BT in the UK with a BT branded "home hub". WiFi is quick to start with but after a few hours the connection speed drops and can only be fixed by restarting WiFi. This is on a nexus 4 with the latest firmware. Google please fix this.

I have/had the same issue, blue good wifi connection but very slow and horrible packet loss. What temporarily fixed it for me was to setup Wifi Direct on my Samsung Galaxy S2, then Wifi Direct connect to that with with the Nexus 4. Wifi connection went from packet loss hell to blazing fast and stable, and stayed that way.

Same problem tried everything (2.4, 5, 20/40 channel bandwidth, n-only....nothing helps.
I habe no problems with a HTC Z connecting to the same router.

Disabling WLAN and enabling helps for a short time, so tis has to be a hardware or software error, not a problem with the router.

Another problem: when the phone connects to the 5GHz channel of my router, it immediatley tells me, that the 2.4 GHz channel is not available any more. This stys when I disconnect/delete the conection to the 5GHz challe too. Only when I disable/enable WLAN it is found and connected with no problem (but still super slow after a short time).

Turning off GPS fixes this issue for me and another user with a BT home-hub in the UK. We both have nexus 4's on stock software .

I'm in the UK as well and I posted here before about the slow wifi speed and wether it is down to hardware or software. Called my ISP TalkTalk and there were pretty sure it was down to hardware. Ordered my replacement from Google and behold, same slow wifi speed. Google need to look into this FAST!

I'm surprised by the number of people who are from the UK having this problem... Coincidence?

Not coincidence. Its the talktalk D-Link router that's the problem. I've
had to rig up an Airport Express via Ethernet to get a second WiFi network
that does work with the Nexus 4.

I agree with #63. I had a talk talk dlink router and suffered the same problem. I could have provably talked them into sending be a new router but there was a good chance it would be another dlink so I picked up a new TP-Link router for £40 and the  WiFi I'd back to the usual fast speeds. My attempts to fix the old router highlighted that it was becoming a bit flaky anyway.

I'm having the exact same issues. When attempting to browse the play store I constantly get the " cannot connect to the play store" and I have to hot retry several times before I can continue. This happens every 10 minutes or so and it's driving me crazy. Also when skiing any type of downloading on my Wi-Fi I get awful speeds. I'm talking an hour to download a podcast but it only taking my iPhone 5 approx 10 minutes to download the same podcast. Something is definitely wrong.

I have the same problem on Asus RT-N16 !!!

I thought my nexus 4 had hardware issues as it wouldn't connect to my home router as it would take 2-3 minutes before even finding it.

What I found out is that there appears to be a bug in jellybean 4.2, ,because i downloaded an app called wifi manager: https://play.google.com/store/apps/details?id=org.kman.WifiManager 

This app is amazing as it sets a widget on your homescreen, you click it, it turns on and your automatically connected to wifi and it never drops for me (yet).

Please can you guys stop commenting as it spams everyone else who has starred this problem this is not a discussion forum if you want to discuss this head on over to xda,g+ or r/android

I just got my Nexus 4 and started to set it up. First thing obviuosly was to connect to wifi, which I did. Then I chose to restore my settings as I have another android phone and a tablet, never done this before and it worked like a charm. I have 18 apps to download plus a shed-load of updates etc. I started the downloads and went away for a while, then came back expecting some of the apps to be installed; still downloading. Then I get a message to update to upgrade to 4.2.1, which I thought was already on the phone, so I installed the system update. Rebooted great. Now its downloading chrome so slowly I think it might have to go back to Google. I have other devices running 4.2.1 with good wifi speeds so I think this is a hardware issue...

What router do you have - the nexus 4 seems to have issues with D-Link
routers!

slow wifi-nexus 4
talktalk d-link 2780 router

It's not just D-Link brand routers that this issue occurs with! I've had the same problem with 2 different Nexus 4 phones on both an Apple Airport Extreme and a Verizon branded HomeFusion router.

My airport extreme has been doing well lately. Pulling 20Mbps down / 4.5Mbps up

I just got my Nexus 4 today. At first it would connect but my speeds were really bad and constantly dropping connection. All I did was update the firmware on my router and everything works. Now it's super smooth and no connection drops.

My router is pretty much stock configuration except for me putting a wireless password and changing the channel.

Rosewill RNX-EasyN400 WLAN 802.11n/b/g Router

Just got my nexus 4 on the 31st of December and I'm suffering from slow Wi-Fi on top of over issues I'd consider to be serious problems.

Other *

I have the same slow wifi issue with my newly arrived Nexus 4.  My router is Netgear RangeMax Wireless Router (WPN824v3).

Same issue on my Stock
Nexus 4  4.2.1
Nexus 7 on the same network gets 15Mbps faster speeds then N4

Uk Nexus 4 user here.

I actually bought 2 Nexus 4 over the xmas period + a Nexus 10. One for me and one for my wife.

I use BT home hub with fibre to the cabinet broadband.  I get 30-40mbit download on my laptop, 25-35 mbit on my Nexus 10, and on both Nexus 4 the speed varies from the normal 30 mbit download to a slowed 1.3mbit download.  At the time of the slowdown the upload remains at 20mbit.  I can get the faster speed by turning the wifi connection on and off or by pressing the reset button on my router.  The Nexus 10 is not affected by this issue.

Turning off GPS if a workaround for slow speed on a BT home hub....

I got the exact same behaviour on my N4 as the one mentioned in comment 82. None of my other devices (including my nexus 7) are affected by slow download speeds. Toggling WiFi on/off or restarting the router will speed up the WiFi on the N4 for a while. My router is an Asus RT-N56U.

I too am having similar issues with my Nexus 4. My ISP(Charter Communications) provides Wi-Fi speeds of up to 30mbps at home, but my Nexus 4 sees a maximum of 11mbps down and 5mbps up. I'm certain that it is not a router issue, mainly because the rest of my devices are receiving speeds close to what my ISP offers.

I have attached two screenshots taken from both my Nexus 4 and my desktop computer.

Have same issues with my nexus 4. I have 80meg fibre optic broadband and getting barely over 1meg on my phone after a while. If turn WiFi off on phone and on again its back up to full speed again. No such issues with my nexus 7 or nexus 10 so its a phone problem not jellybean. Please fix this asap

Same issue. With Airplane mode on I get really fast wi-fi, with it turned off, my wi-fi drops dramatically. I've tried resetting my Airport Extreme router, rebooting the phone but nothing seems to work except enabling Airplane mode with the wi-fi turned on which isn't exactly ideal for obvious reasons.

Ok...here's a good temporary fix that worked for me just now based on some comments on the XDA forums. Go into settings and turn the "wi frequency band" from auto to 5ghz only. BOOM...problem solved, at least while I'm at home til Google issues a software update. As for those that don't have newer routers outputting a 5 ghz band, I dunno what to tell ya for now.

Had the same problem, at home i was connecting to my d-link dir300 router with custome dd-wrt firmware - speed was realy slow and timing out every 20 sec.
But when i was at work i connected to Buffalo whr-hp-g54 with stock firmware, after 2hours of difrent testing - speed was perfect about 54mbit.
Why google hate d-link so much?

I also have the problem that my wifi is horrible slow and I think that if I have bluetooth connected same time it just totally crushes the wifi speeds.
I thought that my Transformer Infinity was bad on wifi since it has same antenna for bt and wifi but I just conducted speedtest on both of them within same wifi network and Infinity is about 70% faster.
So disapointed in Google that they haven't fixed this issue even if it has existed this long time.

I also have the same problem using a BTHub3.

After many tests I can say it happens to me at 5GHz "only", not usable.
No problems with 2.3GHz

I have having the same problem.  Sometimes a reboot fixes it.

I have the same slow WiFi speed issue that others report here. So disappointed! Nexus 7 works fine with my router! Nexus 4 not. The only way I can get higher WiFi speed is to connect nexus 4 to nexus 7 by enabling WiFi direct! But is annoying to need a tablet around just to connect with decent speed to wlan! I hope is a software problem!

Similar issue. I am experiencing horrible performance on 802.11n (2.4 & 5Ghz) and 802.11g on my Nexus 4. Oddly enough, 802.11b works OKish. It does not appear to be an issue with the network since laptops, iPads and iPhones in my house all behave normally. It doesn't appear to be a unit defect since I went through an RMA and the replacement has the same problem (or I'm very unlucky). I've tried disabling encryption but that did not help.

On the router, I'm seeing the Rx rate for the Nexus dropping to 6M while Tx stays at 72M (802.11n). Once buffering starts, the Rx rate spikes up once for about a sec and drops immediately. Eventually, the apps give up and tell me there's an issue with the network.

Had exactly the same problem. On BT infinity at home and nexus was getting 1.8mb download. Switched the wireless setting to 2.4ghz only and it solved the problem, now getting 48mb

same problem with my nexus 4, comparing with a galaxy note2, downloading from google play takes more time, im on a 15mb download wifi network

Same problem for me...my N10 can easily pull 30Mbps up and down, N4 on the same network 2-3Mbps.  I have tried different kernels with no success.  :(

Hi,
I'm having the same problem with my nexus 4. I just did a test where i put my nexus 7 and nexus 4 side by side and downloaded an app from play over wifi. The nexus 7 downloaded at about 1 MB/s but the nexus 4 Downloaded at about 25 KB/s. Turning wifi off then on will temporarily fix problem.

Just bought a new netgear router as I thought it might cure this problem with my Nexus 4 but it exactly the same as with my BT Home Hub so it is definitely a phone problem. When I first turn WiFi on my phone I get over 50mbps download and 20mbps upload. After a few minutes I only get 1mbps download but still get 20mbps upload. What's going on? If I toggle the WiFi off and on again on my phone I get full speed again for a short time. I love this phone but will have to return it if this doesn't get fixed soon. Please sort it ASAP

Sign up another with this issue :(

Same issues here. My N4 works fine on my home network but sucks on the office network. Is Google going to provide solution to this problem? Any fixes?

My specific issue is with a BT homehub in the UK of which my speed will drop from 30mbps to around 2mbps after being connected for about 2-3hours. My issue seems to be fixed by turning GPS off but obviously this isnt convenient.

I stumbled on a "fix" while playing with my APN settings:

1) Go into Mobile networks in settings (Under "more" in Wireless and Networks)
2) Go into "Access point Names"
3) Click on your APN (if you have mutiple active ones do this for all)
4) Under "APN type" remove "supl" from the list (mine now says "default,mms")
5) Reboot

Now my Wifi does not drop speed at all even with GPS on.


So "supl" has something to do with Assisted-GPS but my GPS is working just as well as it did before this change.

same problem:

unusably slow wifi on LG Nexus 4, Android 4.2.1, JOP40D

with linksys wrt54g 11g

excellent wireless signal, all other devices on network are fine

FCC speed test shows between 30-300kbps download speed where other devices show 6-20Mbps. downloads from play store time-out/fail. FCC speed test upload speed is often higher than download speed

tried: disable GPS, select 2.4 GHz only for wifi, power cycle, factory reset, airplane mode. no improvement

plot of bytes transferred vs time from a tcpdump shows sawtooth behavior with long flat valleys at 0.

same here, have used stock kernel as well as Franko Kernel r34 and r46 still the same issues, funny thing is, this is only an issue at home, works fine on my work wifi

Same issue for me. 4.2.1 OS.

Same problem here with my Nexus 4 with my O2 router. Nexus 7 works just fine.

Same here.  If I'm streaming something to my Xbox, speed tests on my Nexus 7 drop to between 100 and 1,000kbps, when I stop the streaming, speed comes back up to 7,000+kbps.

Post #104 by mcur.... Seems to have fixed the problem, for me anyhow. I did what he suggested 5 days ago and have had full speed WiFi on my nexus 4 ever since. Brilliant, thanks.

Same here,
slow Wifi, after Reboot the Wifi conection get full speed and slows down after a few hours. Same problems with 2 different N4 devices ( the 1st from december & a  warranty exchange device from january, the exchange was because a speaker problem).

Indeed post #104 also fixed the issue for me and I can't see any difference to GPS either.

Thanks!

Same here. Will try the #104 solution.

Now I have a BT problem (sometimes I have to reboot to turn BT on), a 3G-problem (after being connected to a wifi for a couple of hours I have to reboot to get a 3g data connection) and now also a wifi problem. How great is that.

I tried #104 but when I went into "more" then "mobile netwrk settings" I didn't have the access points option. I just downloaded 4.2.1 a few days ago. I'm accessing my Arris cable modem directly.

i tried the method in #104 it dosn't work for me (might do for others) im in the UK on vodaphone using Sagemcom F@ST2504n

disbeling pgs and nfs dosnt work
trying method in #104 post dosnt work

guess i'll just wait for an update to roll out which will fix the driver

Same here, try #104 don't work.

Don't know why, it's just with the play store...

I've just got my N4 thanks to new Play Store refills. Received 2 days after order. Very speed !
Unlike the Wifi...
Like everybody else here, the wifi is horribly slow : about 30kB/s instead of 600kB/s...
Wtf ?
And there still isn't any Google/LG official announcement on this issue ?!
Praying that it's a software bug and that a fix will come very, very soon !

Please Google, don't make me regret this purchase !

Just received my Nexus 4 on Friday, wifi isn't just slow, it's completely unusable on my home router, a D-Link DSL-2780 supplied by TalkTalk. Having tried at my girlfriends house, it works great (A Thompson router, supplied by O2).

Am currently using a workaround by sharing internet from my Mac to the phone, but it's very far from being ideal.

Wifi unusable on a network powered by a Movistar Amper ASL-26555 router.

This seems to be the case for many users on these forums (in Spanish): http://www.htcmania.com/showthread.php?t=492754
http://comunidad.movistar.es/t5/Ayuda-T%C3%A9cnica-de-Movistar-Banda/Nexus-4-y-Router-Amper-Asl-26555/td-p/912032

If it's any consolation, iPhone 5s seem to be having the same problem.

Galaxy Nexus and a whole bunch of other devices work just fine on this network.

This guy claims to have found the solution but I haven't gotten around to trying it yet:

http://www.htcmania.com/showthread.php?t=492353

He's changing the Signal-Interval setting on the router from 100msec to 10msec (as per this screenshot: http://www.htcmania.com/showthread.php?t=504836)

This looks related to DTIM and the "Minimize battery usage when Wi-Fi is on" setting
(cf. http://www.anandtech.com/show/6440/google-nexus-4-review/4)

Has anyone tried unticking that box?

un-checking "Minimize battery usage when Wi-Fi is on" solved this for me.
wifi speed is now 30+ times faster than before.

thanks for the tip
T.

Un-checking "Minimize battery usage when Wi-Fi is on" solved this NOT for me though. Sadly.

There must be other bugs at work here, too.

I'd love Google to comment at some point so that people know that it is being worked on.

I really guess many more people are experiencing this without noticing really. The dark figure is probably much higher than can be guessed from the posts here.

Not a single setting on the phone itself has made the blindest bit of difference for me, I've ticked and unticked every possible option, multiple times.

However, the tip from #121 worked - http://www.htcmania.com/showthread.php?t=504836 - it allowed my phone to actually load content. Connection was still sketchy, but at least I could load pages, email and the play store, etc. Previously they all just timed out.

I've now set-up a separate wireless device connected to my D-Link via ethernet, purely for the Nexus. Ridiculous, but it's the only solid solution until there's an official fix.

It does seem we're possibly discussing different bugs here though, my problem is that the phone connects to the D-Link DSL-2780, and stays connected, however refuses to load anything, play store times out, pages hang, nothing will work as it should. Those who are experiencing disconnections are possibly experiencing a different (Yet similar, and equally annoying) problem? Though it could all be related to shoddy drivers?

Returning my device. I waited several months for this to become available and have been presented with something that is known not to work on wifi unless you fiddle round with stuff. Biggest tech let down I think i've experienced considering time I waited.

In two weeks time an Android update seems to be due. Let's hope this is one of the bugs this update is supposed to fix.

Having the same issue over here. Wifi slow, it works better with the #121 trick but it still hang after a while and need to stop/start the wifi of the phone to have a the speed back. Hope google will do something about that.

N4 Ver. 4.2.1, Build number JOP40D. Never get better than two bars of signal, sometimes it can't find the router, 15 feet away. Constantly drops connection and would wildly connect to someone else router (unsecured) but wouldn't connect to mine sitting right next to it. Have cancelled two pending deliveries, 16gig devices because not able to deal with the problem that a non tech guy like me.

@#128 - Could be a different problem. I think almost everyone else here is full signal strength and still getting zero bandwith.

Wi-Fi is pretty much useless for me. YouTube can't load a video without buffering every 10 seconds

I had slow speed issues with D-Link DIR-825 on the 5Ghz(N standard). The signal was 100% but the download speed was 2Mbit. I've followed the instructions presented here http://www.dd-wrt.com/wiki/index.php/D-Link_DIR-825 and updated firmware of the router with this non official, custom firmware.
This solved the problem for Nexus 10 and the wifi speed is more than 80Mbit.

Send them straight back to google, if enough of us do this they will have to implement a fix in this defective product. I am on my second Nexus 4 which still has the same wi fi fault being described here. This one will also be going back. Very easy return process by the way, just go on the google play help site, request a call back to your home, describe the problem, tell them about all the other users on these forums having the same problem and they will get a replacement in the post to you. You can only do this during the first 16 days of having the phone delivered to you.

This is the contact link I used to return my Nexus 4 (United Kingdom)
By the way, I am with TalkTalk using a D Link 2780 router, this seems to be mentioned quite a bit in the forums on this subject.

http://support.google.com/googleplay/bin/request.py?&p=play_contact&rd=1

I too have D-link dsl 2780 router.

+1. unusable wifi with my nexus 4 with talktalk d-link 2780 router

Luckily the router in question was at my girlfriend's house not mine. I have spoken to a Googler, they have offered me a replacement after exhausting their troubleshooting. The Wifi works brilliantly on other networks though (not hardware issue) so I will keep this phone in the hope that a software fix is issued OTA.

Not really good enough to work on some networks only though... not for a flagship product like this.

SOLUTION:

Alright it took me a few hours of tinkering with the driver, but here it is..

DO THIS AT YOUR OWN RISK, I'm not responsible if your phone self-combusts and causes you and your house to burn down with it.

You need to be root on your phone for this to work and to have adb (USB debugging) enabled.

> adb shell
shell@android:/ $ su
shell@android:/ # mount -t remount,rw /dev/block/platform/msm_sdcc.1/by-name/system /system
shell@android:/ # cd /system/etc/wifi                                          
shell@android:/system/etc/wifi # cp WCNSS_qcom_cfg.ini WCNSS_qcom_cfg.ini.bak # MAKE A BACKUP

#### On your computer, run this
> adb pull /system/etc/wifi/WCNSS_qcom_cfg.ini
69 KB/s (5577 bytes in 0.078s)
# Edit the WCNSS_qcom_cfg.ini file on your computer:
# Replace the line that contains "gEnableBmps=1" by "gEnableBmps=0"
# Then,
> adb push WCNSS_qcom_cfg.ini /sdcard/
106 KB/s (5577 bytes in 0.050s)

#### Back again in the adb shell:
shell@android:/system/etc/wifi # cp -v /sdcard/WCNSS_qcom_cfg.ini WCNSS_qcom_cfg.ini

Reboot, and you should be getting normal speed on all networks.

BMPS means Beacon Mode Power Save. I don't really know what that means, and what the implications of changing that setting are, particularly on battery life.

Maybe there's a better way to tinker with the settings to retain the battery benefits and regain the ability to use all networks?

So far Google hasn't showed any sign of even looking at this issue despite the hundreds of frustrated customers, so if you guys find better settings, please post them here. Thanks.

Good luck!

I had also very bad wlan perfomance with Nexus 4 - it was unusable. The situation could be solved by changing the beacon intervall from 100ms to 20ms in the wlan settings of our router, it is a Logilink WL0081.

Perhaps this also helps with other routers.

Update on #136: N4 went from 80% to 50% battery in 6 hours, without any user input, with cell and wifi on and BMPS turned off.

Not sure what the normal rate of battery consumption is but I'm pretty sure my GNexus was much more efficient than that.

Regarding comment #136: thanks for the info you posted! I tried out your method and thought it had finally fixed things for me, but unfortunately such was not the case.

After turning off gEnableBmps, my Nexus 4 was (for the first time ever) nice and zippy with wifi on my Verizon HomeFusion router. Previously, it was incredibly slow with this router and none of the tweaks I'd tried making to both the phone and the router ever made any difference. After implementing your above method, it was pulling stuff down from the Play Store at about 4MB/s, whereas previously it was around 200KB/s.

But after I started doing some more testing with this change to my phone, I found that either rebooting the phone or letting it sit unused for a while would knock the wifi speed severely down. Turning wifi on and off didn't seem to reduce the speed, however.

Then while using my phone today (still with the above change enabled) I noticed my battery was taking a huge hit, compared to what it's normally like. The battery usage was showing the Android OS as the culprit (makes sense, given what I changed on my phone) and was using even more of the battery than the screen was.

So I undid the change and am now back to dealing with crappy, slow speeds all the time on my phone. Sigh.

I'm really sick of this problem. :(

Same problem. Also periodically loses WiFi connection entirely.

The solution in comment #136 worked for me, and has persisted for 3-4 hours or so working correctly, even through reboots.

For the record, there appear to be numerous different WiFi connectivity issues with the Nexus 4. If #136 doesn't solve it for you, it means you have a different problem than is being discussed by the majority of this thread.

In my case, my Nexus 4 performed reliably (albeit at a max of 7-8Mbps due to congestion) to my router on the 2.4Ghz band, but on 5Ghz would drop to double-digit kbps after an initial 30-60 seconds of full speed performance.

This initial period of proper function followed by a major dip in speed is what has led so many people in this thread to say "I've fixed it!" and then a few hours later post that it was a false positive. This one does not appear to be a false positive. At least one of the N4 connectivity issues definitely depends on Beacon Mode Power Saving being disabled.

I have not compared battery performance after disabling it (and probably will not tonight as there are approximately 2 feet of snow outside my window and I may lose power at any moment) but I would expect it intuitively to have a dramatically negative effect on battery life. However, at least now we have a clue as to where the problem lies.

@#139 - If you were getting 200KB/s prior to fixing anything, it doesn't feel like the same problem as the rest of us where the connection is virtually unusable. It could be related though.

@#141 - Thank you for the feedback. I've actually measured the battery impact (roughly):

When the phone is idle (screen off, no user actions), with cell and Wifi on, good signal, for 5+ hours:
- With BMPS turned off: battery loses ~ 5% per hour
- With BMPS turned on:  battery loses ~ 0.5% per hour

So yes, it makes a huge difference and I'm hoping there is a better fix.

There's reason for hope: I've E-mailed a Google developer and he said he would follow up on this.

#136 and #121 seem related. for me simply unchecking the minimize battery usage option made a huge difference (see #122)

I had reliable connection to access point with good signal strength, but close to unusable bandwidth. Nothing seemed to help (GPS on/off, BT on/off, reboot, airplaine mode, factory reset, etc., changing channels, changing DTIM interval on router) All other devices on the network worked fine.

after unchecking that option I have reliable connection and 10+MB bandwidth in FCC test -- going on 5 days already, so it's not a short-lived pseudo improvement.
I can't say how this affects battery life, though, since I didn't keep track of it before

this is with N4, Linksys WRT54G, DD-WRT firmware (v24-sp2), 802.11g only. the beacon interval is 100ms, DTIM is 1

T.

@#143 - Have you tried setting the beacon interval to 10ms and turning on the battery saving features?

I have already done a post here (#84). I tried the suggested method with setting the beacon interval to 20ms but it didnt fix my problem.
I just want to clarify that I do not have the problem that my wifi dosent work at all, it is just that the download speed is not great. When the phone first connects to my home network after being out of range I usually get download speeds at 30+ Mbit/s but after some minutes it drops to 8 Mbit/s and stays there. None of my other devices act the same, they all have a constant high wifi speed. No router firmware or settings seems to help. At the university I dont have the same problem.
Google please fix all these wifi-related problems with the next update! It seems that something with the wifi on the n4 isnt what it should be.

Also have a low low signal with WiFi.Canada region . I'm 10 feet away from router and showing 2 bars and very slow download speeds . I'm on a 56mbps connection .

Wifi appears to be connected, but speed fluctuates and connections time out.  
I have tried most fixes suggested above.
I will try a different router.

Device: Nexus 4
Build:  JOP40D
Android: 4.2.1
Router: Actiontec MI424WR
Wireless signal: 11b/11g
Priority-High

I changed the fragmentation length and RTS threshold on my router and I'm getting 20+ down, was getting 2-4 Mb down before no matter what.  And like may others here, some changes before used to give high speeds for a minute or so, this is working for a 150MB download so far.

I lowered Fragmentation length from 2346 to 2306, and RTS threshold from 2347 to 2307.

@#148 - I've tried every value of RTS/frag including yours, no difference: I get 0 throuhgput. I think the issue is mostly DTIM/signal interval for many of us (and that router won't let me change that setting)

speed fluctuates on my N4, most of the time it is slow. Speedtest would go from 4000kbps to 35 000kbps and drop right back down to 2000kbps.

@#152 - Speedtest doesn't just test your local WiFi speed, it also tests your connection speed all the way to the Speedtest host..

Anyone had the 4.2.2 update yet? If so has it cured any problems? I see that Google are rolling it out on Nexus 7 and 10. Maybe Nexus 4 tomorrow?

I have the same problem. With a router that provides around 15 mbit of internet speed I am not even getting 1 mbit. All my other devices (Nexus 7, Macbook Pro early 2011) work fine...

I found something that has improved my wifi from being at best a 1 out of 10 service to being about a 6 out of 10 service. I have deleted Google currents from my phone. Not sure if this is a coincidence or not. But my wifi on my Nexus 4 at home has now got a blue signal bar and most of the time connects to websites, Play store etc. OK. Even download speeds are quick although sometimes they do stall for a few minutes before resuming. Worth a try, let me know if this improves things for you. I went into:..

Settings..
Apps...
All...
the select currents and uninstall

I updated to 4.2.2, the problem is still exactly the same: unusable wifi on certain routers.

To me, this only occurs when I am on a wireless N network. Going down to G, my wifi speed stays at a good constant speed with no drops.

@#159: what you described was also true for me.

If you have root access, please try the solution in comment #136 as it worked for me.

After updateing to 4.2.2 with high hope this would be fixed, it indeed was not fixed. My wifi at home works only intermittently with my Nexus 4 and usaly shows full signal but a dismal throughput rates of around 0.15 Mbit on a 10Mbit connection. My wife's iphone and ipad work fine as well as my kids ipods. My Nexus 10 also works fine on this same connection. Seeing 4.2.2 did not fix the issue I went to playing with the router settings. What I found is that if I set the 2.4 Ghz band from mixed b,g,n to G only the issue seems to have gone away. I am using a Linksys V4200 with the latest cloud connect firmware. Hope this helps someone.

So I got home today and Wifi just wouldn't turn on with 4.2.2 -- i.e. I couldn't even get to the list of networks. I rebooted several times to no avail. I eventually restored my backup of 4.2.1 and now it works again... *sigh*

Still the same issue after 4.2.2 update. A short time after I have connected the phone to my home network the speed drops from 35+/14 Mbps to 8/11 Mbps. So disappointed!

Also managed to update to 4.2.2, wifi bug still persists. I read somewhere that this will be the last 4.x.x update and the next one will be version 5 to be released April or May at Google IO.

Following the solution on #136:
1. Edit the WCNSS_qcom_cfg.ini file on your phone in /system/etc/wifi with any Root Explorer app
2. Replace the line that contains "gEnableBmps=1" by "gEnableBmps=0", save the file and check its permissions
3. Reboot and enjoy working WiFi with your router (no need to change its settings in the first place.)
All done.

@#165, you're crushing your battery performance when you do that as indicated on comment #142. It works, but it ain't for free..

So I changed the "signal-interval" (beacon related?) on the Movistar Amper ASL-26555 Homestation router from 100ms to 10ms and got improvement:

I went from getting zero packets through, to downloading at 28KByte/s and uploading at 90KByte/s.

Both are much less than the connection can achieve but it's better than nothing..

It's basically a faulty product, it's crazy that so many are experiencing this same issue and Google choose to ignore us. Send the phones back and keep demanding a replacement, it's the only way they will sit up and take notice!

Same problem tryed everthing and even the 4.2.2 update didnt help!

@#167 no, my battery performance is ok, but I have lowered the beacon interval to 10ms, and I have wifi battery optimization on.
