How to set the wifi protocol in the network manager

Support Network
1

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> 802-11-wireless.band "a"

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