I have installed Ubuntu Server 22.04.2 LTS on a rasberry Pi 4. I am attempting to connect the wifi to my school wifi. I am getting many of this error:

brcmfmac: cf880211_set_channel: set chanspec 0x1234 fail, reason -52

I have set up the network_manager in the same way I always do:

nmcli> set ipv4.method auto nmcli> set 802-1x.eap peap nmcli> set 802-1x.phase2-auth mschapv2 nmcli> set 802-1x.identity robotics@brandeis.edu nmcli> set 802-1x.password "three words" nmcli> set wifi-sec.key-mgmt wpa-eap

Does anyone have a clue?

Thanks!

That could mean you don't have your pi set to the right regulatory domain, so it thinks it is illegal to use the WiFi channel your school's WiFi is on. You can set the regulatory domain with netplan using the regulatory-domain setting, as in this answer: https://askubuntu.com/a/1480856/164539

You should set it to the country code for whatever country you are in (e.g. US if you are in the united states).
