I'm not able to connect to a wifi network on this distro and can't find the cause.

Wifi driver: iwlwifi

What happens at fresh install:

• Wifi networks are being detected, altough they sometimes disappear after tinkering with settings


• When I try to connect to a network the password dialog continues to show again after some seconds


• It turns out that by default all wifi connections are set to infrastructure mode. Changing it to "access point" solves the password dialog loop


• After changing the mode the connection moves on but sticks on "Setting network address", then gives up after a while.



• Setting manual IP is not what I prefer because I don't want the hassle to set it for every network connection when it's supposed to work normally. But I accept having it working at least at home.




• Using manual ip it connects but there's no traffic.

The IP configurations is:

Dns Server 1.1.1.1

Search domains: blank

Address: 192.168.1.110

Netmask: 255.255.255.0

Gateway: 192.168.1.254

No routes.
