I just installed Manjaro ARM KDE on my Raspberry Pi 4. On startup, it gets to a point in the logon and stops for several minutes. When it restarts, there is a message saying that it failed to start the Network Manager. When I finally get to the GUI and try to log onto my WiFi, it doesn’t detect my 5 GHz channel. It sees my 2.4 GHz channel but won’t connect to it. With other distros, with the notable exception of Raspberry Pi OS, I have had to connect to the 5 GHz channel as they won’t connect to the 2.4 GHz channel either. All my Windows computers and portable devices connect to the 2.4 GHz channel with no problem. Any help with this problem would be greatly appreciated.
