Xperia Z5 Premium internet switches itself off despite being used.
Hi @Jonnymac
Can you please elaborate?
Is it mobile data or Wifi that is switching itself off?
Let me know 
My xperia z5 premium turns off the internet without any prompting from me. This happens whilst I am using the internet for instance streaming Sonos music. It is very frustrating.
The wireless connection to my home internet is supposed to automatically on. But the phone continues to switch off the connection leaving me reliant on mobile data.
Is it set to never sleep? And wifi added to battery optimisation?
There are no limtations set on the internet use, sleep or otherwise. It is a glitch not a phone setting as I have checked and rechecked all the settings. I have factory reset and nothing changes.
Checked router settings? Is there any ios or Apple devices on the network?
Himy WiFi keeps turnning itself off.
There are only android and my windows computer on. They have never interfered before. My router has a permanent monitor to keep it switched on.
