WiFi suddenly disabled

[hqaddomi]

Sometimes the Xperia Z1 phone disables my WiFi without asking me. I just discover that when I check the phone and find the WiFi sign off. The problem is I don't want it to disable the WiFi under any circumstances.

Note: I noticed that with my previos ACRO S phone but I thought it is only a problem with my phone hardware or something.

Do you have the option "Keep Wi-Fi on during Sleep" set to always? Settings/Wi-Fi/Options (3 dots)/Advanced.

Another option is Power Management/Stamina Mode. If this is enabled it will disable Wi-Fi when the screen is off.

Sounds like Stamina. You can alter its behaviour to allow for lower battery levels before it intervenes

It should not matter that stamina mode is on.. Its a function of this device, and so it should not conflict in with any other function.. Before the last update i never Had this problem. So this should be fixed a.s.a.p. Caus everytime i have to shut down en restart my Phone. This is very anoying and so far i have reccomended other phones to people because of these buggs and no update to fix it...
