Force NetworkManager to connect to 2.4Ghz

Update, for anyone else interested in doing the same I managed to figure it out.

Ask NetworkManager to scan for all the available APs and include the BSSID, Frequency and signal quality info in the list.

  1. nmcli -f in-use,ssid,bssid,freq,signal,bars dev wifi

Your router broadcasts 2.4ghz and 5ghz under the same SSID, so what you want is to connect to the 2.4ghz specific BSSID.

  1. nmcli d wifi connect XX:XX:XX:XX:XX:XX

All set.

I haven’t figured out how to make that preference persist across reboots though :frowning:
