WiFi drops when phone in standby

rouleur — Mon, 20 Jun 2016 06:56:13 GMT

Since I have updated my Xperia Z3 Compact to Android 6.01 it looses connection to my home wifi as soon as the phone switches to standby. This is very annoying especially for music streaming. I have tried all the tipps found in the forum on similar issues. WiFi on / off, flightmode on/off, several restarts, reset WiFi settings, start in safe mode, yesterday even reset the phone to factory settings but still have the same problem. The issue is only with the Xperia phone. My partners iPhone as well as my Windows phone stay connected on same network, my Xperia stays connected on other networks as well. Any hint what the issue could be?

@rouleur have you checked the wifi sleep policy? Can you set it to always keep wifi on during sleep?

Have you also tried out a different router?

@rouleur You can only try a software repair using Xperia Companion before you send the device to your Local support.

Yes, you can install LP using flashtool, but your warranty might be broken afterwards.

Question, is your wifi router a 5ghz? Do you use Bluetooth devices?
