Xperia Z5 - Wifi and bluetooth won't turn on

[levircurtis]

The subject basically sums it up. I'm using an Xperia Z5 and my wifi and bluetooth will not even turn on. When I go to the drop down screen, nothing happens. When I go through settings, it shows wifi is turning on, but nothing happens.

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! 😞

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.

While I understand your frustration, but using vulgar words and curses won't help your case. Keep it clean, please.

Tried your trick, it helped.

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

Hi, i was also facing the same problem in my xperia z5 premium dual, i tried everything like reset,hard reset, software repair by sony pc software and flashtool to fix this problem but nothing works. When i become tired form every ways finally i fixed it by simple way.

Goto about phone in setting+ status + charging optimization. Make OFF your charging optimization. It will restart your phone. Now your wifi and Bluetooth both will work smooth .Enjoy
