I have the same problem (used to work in 8.0 and stopped in 8.1 preview 1).
I call it from a `Fragment` attached as a headless-fragment (without any own view).

My Code (this returns always `<unknown_ssid>`):

```kotlin
private val wifiManager: WifiManager by lazy { context!!.applicationContext.getSystemService(Context.WIFI_SERVICE) as WifiManager }

private val isInCorrectWifi: Boolean
        get() {
            val connectionInfo = wifiManager.connectionInfo

            if (SupplicantState.COMPLETED != connectionInfo.supplicantState) {
                debug("isInCorrectWifi > not connected to any wifi")
                return false
            }

            val dataReaderSSIDInMarks = "\"testWifi\""
            if (dataReaderSSIDInMarks.isEmpty() || dataReaderSSIDInMarks != connectionInfo.ssid) {
                debug("isInCorrectWifi: not connected to correct wifi (should be $dataReaderSSIDInMarks)")
                return false
            }

            return true
        }
```
