[Xperia Z1 Compact Android Development] filas312:
It works at times (i.e. music playback seems okay), but any kind of latency-reliant net application seems to have problems, at least for moments - until the WiFi gets restarted by hand, and not even all the time it'll be fixed when I restart it manually. Sometimes it just won't work.

The log below is possibly connected; I've had the same problems on 7.1.2 and same messages seemed to happen.

In case you're not willing to take a look at it, just tell me :) I'm here to note that there's some kind of problem - either anything to do with sources back to 7.1.2, drivers, or maybe a hardware fault on my side.
