Wifi not working properly

[SasukeJ]

Hi, for a couple of weeks i'ts been impossible to use Wifi in my Z3. It's a loop, connect - couple of seconds - disconnect - scan.

Here's a video: https://www.dropbox.com/s/vl8221j836kliky/ScreenRecord_2016-05-04-18-58-54%5B1%5D.mp4?dl=0

I tried to solve the problem from the smartphone and from the router.
- Changing wifi channels
- Using another security and encryption
- Trying 2.4ghz and 5ghz

- Static IP
- Safe mode
- Disabling optimizations
- Changing rom

Any help? I really need to solve this.

I have the exact same issue on Xperia Z3 Dual Marshmallow. Have tried everything but it just disconnects and then reconnects again. Other phones are working fine with the same Wifi.

All networks or just this one?

It was with all networks. I repaired the phone software yesterday with Xperia Companion and so far it seems to be working fine now.
