Re: Xperia Z5 - Wifi and bluetooth won't turn on

October 2017 - My z5 has just restarted itself and now the wifi won't turn  on at all.  Tried all simple fixes to no avail.  Are Sony trying to phase this phone out or something? Lol.

 

Update - on again after about 10 restarts

 

Update - ITS HAPPENED AGAIN! :-(

Re: Xperia Z5 - Wifi and bluetooth won't turn on

I have the same issue, and this is how I solved it.
WiFi turns "on", but it does not see any networks.
Bluetooth won't turn on.

This is how I solved it.

1. Go to Settings -> About Phone -> Support.
Run the "Wi-Fi" test.

It takes a while, but it passes.

2. Run Bluetooth test. 

3. Then reboot. My Wi-Fi now (often) starts as it should.
Please note that the problems comes back from time to time.

This is a work around, not a fix.

Tried your trick, it helped.

Interesting though, Wi-Fi doesn't hold the connection, it keeps loosing connection and then reconnects again ....
