[Bug 2160416] Re: Unable to connect to 6 GHz networks with MT7921K

apport information ** Tags added: apport-collected stonking ** Description changed: I am unable to use 6ghz WiFi with this chipset in Kubuntu 26.04. Only just noticed it because I upgraded my mesh WiFi at home to ASUS BT8, and my other devices work fine. Running "iw list" shows all 6ghz disabled. I tried forcing Swedish region with "sudo iw reg set SE" but no change. I found a bug report here, not sure if this is the same or not https://bugzilla.kernel.org/show_bug.cgi?id=218731 Happy to provide any additional information needed to help solve this.
