Test your phone with other WiFi connections, and also test if other phones/laptops get disconnected from your router and report back.

Thank you for reply! On other devices (PC,Laptops,and other android phones) phone still connect for a minute or two and then disconnect... I tried factory reset on phone and router but no luck. Btw on other WiFi connections same ...

Hi @maybeadam

First I suggest doing a backup of your device information: How to backup?

Then try to repair your device using PC Companion.

I hope can be useful.

Hi @maybeadam

What happen with other devices? For example, if you connect a Laptop or another Android device via wifi, they also lost connection after a few minutes?

Hi @@maybeadam

So after doing a backup of your device information, have you also try to update your device to the last OS? Which version of Android are your Xperia device running ?

Hi @maybeadam

I think could be a hardware issue. I would consider in this case contacting a Sony service at:

I'm at disposal for any question.
