How can I get the band (2.4 / 5 GHz) selection back in wifi settings? (ubuntu 20.04)
The dropdown menu was removed from the UI (I could not find the reason).
But there is a work-around, by checking the manual of nm-settings:
- Locate the targeted WiFi connection profile in
/etc/NetworkManager/system-connections/nameofconnection.nmconnection - edit with
sudo nano /etc/NetworkManager/system-connections/nameofconnection.nmconnection - Under section
[wifi]add following entry- for 2.4 GHz only
band=bg - for 5 GHz only
band=a
- for 2.4 GHz only
- save changes and connection should use the new configuration
