I am trying to connect to a wifi network with NO internet using the following code:

val specifier = WifiNetworkSpecifier.Builder()
.setSsid(wifiName)
.setWpa2Passphrase(wifiPassword)
.build()

val request = NetworkRequest.Builder()
.addTransportType(NetworkCapabilities.TRANSPORT_WIFI)
.removeCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)
.setNetworkSpecifier(specifier)
.build()

val connectivityManager = context.getSystemService(Context.CONNECTIVITY_SERVICE) as
ConnectivityManager

connectivityManager.requestNetwork(request, networkCallback)

The dialog from the system appears correctly stating the name of the network, but when I press "Connect", it does not connect to the new network. The network callback however receives "OnAvailable" with the correct network instance.
I could not reproduce the issue on other devices (On Pixel 5 it connects properly).
Current target sdk is 31. If I change it to 30, the connection works properly.

This is work as expected. As Pixel 6 support STA+STA feature, please check: https://developer.android.com/reference/android/net/wifi/WifiNetworkSpecifier

And the network callback receives OnAvailable means the connection is success. But as it's connected using the secondary STA, the Wifi settings will not display as connected.

On Pixel 4A, the secondary STA is not supported. Also if you target less than S(31), device will using the primary STA to connect, which will display in the Wifi settings.

We too are struggling with this issue and have two questions.

How can the app communicate with secondary WiFi?
The app is always communicating with the primary WiFi and cannot seem to communicate with the secondary WiFi.

Is it possible to disable the STA+STA feature from the app?
We would prefer to always use the primary WiFi as we have done with previous Android devices.

The network callback will return the actual network which is using for connecting to the requested peer, no matter primary or secondary. This is the way app use secondary Wifi to do the communication.

This not way to disable STA+STA from the App. The only way to do that is keep the app's target level less than S(31)

Thank you for your answer. We are using the secondary network to make http request. Currently, we get a timeout because they are routed to the primary network. What do you suggest for us to do in order to avoid this routing to the primary network?

As indicated above "The network callback will return the actual network" -> any time you use ConnectivityManager to request/create a network the callbacks will return a Network object. You must use this Network object to create a socket to communicate over that specific network. If you do not then you will simply get the default network. If you're using a library to create a connection than you may be limited by the available APIs of that library.
