Hi @Specialized1,

Welcome to the community.

Another thing you can try is simply deleting the WiFi network and reconnecting to it. 

To remove the network go to Settings > WiFi > Tap and hold the problem network and choose "Forget Network".

Can you also confirm if this happens on every WiFi network or just the one?

It happens on SOME routers... I don.t know wich... I tryed this but it doesn.t work

It worked on safe mod, but after i turned the wifi off and then on again 2 times, i didn.t work anymore... It is weird... My sister has sony xperya z1 and again the same problem. I had an older router and that oane worked just fine

Do you guys have any other solutions? I really apreciate your work:)

@Specialized1,

If the issue is only happening on some routers, not all, and your sisters phone is experiencing the same issue, it's my best guess that the router is the problem.

You can try changing the wifi channel in the routers settings, maybe even factory reset it and reconfigure it. Failing that, try another router.

Ok... But all laptops work just fine, and all other mobile phones work just fine

Yeeey... I found a solution... Someone told me to deactivate the firewall from the router.s settings... And i did and it works perfectly... Now... Which are the consequenses of deactivating it?
