My phone WiFi dont work after update

[Aydnie]

Hi,

I just bought a new xperia phone yesterday. Tonight i did the update but after it it don't want to connect me to the wifi anymore. It says connected but no internet access. That worked with that wifi before the update, and the wifi still works in my old phone. Ive tried safe mode but that dont want to work. I have tried to go in 192.168.1.1 to see if i could access but i can't. I changed my phone ip in the wifi settings to 192.168.1.128 but that don't work, same for the dns at 8.8.8.8 and 8.8.4.4

The update i did was the one of the 5 may 2017 (android 7.0)

Help me please ive been searching for hours
