My Sony Xperia E3 running Android 4.4.4 KitKat has had some trouble connecting to wifi recently. Wifi connection is randomly lost sometimes after standby mode. When trying to reconnect, my phone would not detect the local networks, which could be fixed by going in and out of airplane mode 1-5 times or rebooting. The problem has worsened since; i can't even turn wifi back on again (the switch gets stuck in that grey transitional state). Airplane mode and rebooting did not help. Please help!
