Here is an AI generated summary of troubleshooting that I have done today, which lets me see the 6ghz network but not connect to it.
Module Parameter Adjustment: Configured options mt7921_common disable_clc=1 in /etc/modprobe.d/mt7921.conf to check if channel load calculator restrictions impacted the connection (resulted in no change). Router Channel & Bandwidth Tuning: Restricted the ASUS ZenWiFi BT8 router's 6 GHz channel bandwidth to 80 MHz to eliminate wide-channel allocation drift, but the router continued broadcasting beacons extending into upper-band frequencies (Channel 196 / 6375 GHz). NetworkManager Profile & BSSID Management: Deleted and recreated NetworkManager connection profiles for the 6 GHz SSID to clear cached BSSID associations. Attempted manual BSSID locking and forced static frequency bindings (freq=6135) inside runtime Netplan/NetworkManager connection keyfiles under /run/NetworkManager/system-connections/, which resulted in immediate association timeouts (ssid-not-found). Kernel Regulatory Conflict Identification: Confirmed that the underlying issue stems from a conflict between regional regulatory limits (Sweden's kernel restriction blocking 6 GHz channels above 93 / 6415 MHz) and the router's upper-band broadcast behavior, causing wpa_supplicant and the mt7921 driver to abort the WPA3-SAE handshake. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2160416 Title: Unable to connect to 6 GHz networks with MT7921K To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2160416/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
