How to set the wifi protocol in the network manager

Whenever I create a new wifi connection in the network manager, it uses 802.11g (2.4Ghz). The wifi is quite bad because my neighborhood is extremely busy in the 2.4Ghz range.

How do I tell the network manager wifi to use 802.11a / 5Ghz?

To set only 5Ghz network you can do it:

nmcli connection modify <your-network-ssid> "a"

If you want 2,4Ghz set value to "bg"

  1. Thanks
  2. Are you saying, that it has to be done at the command line each login?

No, just once.

Thanks for taking the time help and explain
