Re: wifi connection issue with arch kde

If you "need that KDE gui" you have to remove/disable netctl and use NetworkManager instead the KDE applet uses NetworkManager and netctl/wifi-menu and networkmanager directly conflict with each other.

Re: wifi connection issue with arch kde

Disable dhcpcd.service and stay away from wifi-menu/netctl if you want to use networkmanager

Re: wifi connection issue with arch kde

Did you configure networkmanager to use dhcpcd? This would be good information to provide in the opening post if you've done adjustments like these.

Re: wifi connection issue with arch kde

Ok, I remove dhcpcd and then reboot but it didn`t work then I used netctl to enable one of my wifi profile (which made by wifi-menu) and reboot . it is really weird but now it`s working.
Obviously there is still something wrong with my system and that will come back to me some other time so I would be appreciate if you help me fix this for good

Re: wifi connection issue with arch kde

Stop using netctl, you will only deepen the issue. Remove/disable any netctl profiles, netctl and networkmanager are inherently incompatible
