I have been working this issue for several days and have not been able to make any progress. I have searched this site and others without finding a resolution. 2.4Ghz & 5Ghz works fine on my laptop, 6Ghz work on my Samsung phone but not on my laptop. I can see the 6Ghz SSID but when I try to connect it fails. Laptop is up to date with latest updates as of this posting. Router firmware is latest edition. Country is USA.
Laptop - HP Victus 16 with Mediatek MT7922 WiFi module.
Router - Archer AXE5400 v1.0 Firmware Version 1.3.1 Build 20241101 rel.60873(5553)
Router 6Ghz settings: security: WPA3-Personal (other option is "Enhanced Open" Channel Width: 20/40/80/150 Mhz Channel: Auto Mode: 802.11ax only (grayed out, not able to change)
I ran the Wireless Info Script. Posted here: https://paste.ubuntu.com/p/8jMpbqkdJ4/. WOW...that captured a lot of data!
I never had 6Ghz working on this laptop. A fresh install of Ubuntu 24.04 was loaded after wiping hard drive. Ubuntu is the only OS on the laptop. I've been working with Ubuntu since the days of 10.04. I'm not an expert but can work around most issues. This one has me stumped.
I would really appreciate someone reviewing the linked script results and working with me to resolve this issue.
Thanks you!
David, Thanks for your reply.
Attempted all four possible setting mentioned above. No change. Can connect to 2.4Ghz and 5Ghz wifi. Cell phone can connect to 6Ghz. Ubuntu laptop can see the 6Ghz SSID but will not connect. Here are some additional annotated logs from dmesg:

I'm not sure where to look for the reason it fails to connect to 6Ghz.
EDIT:
Dual booted my laptop with Win11. 6Ghz working on Win11 but not on Ubuntu 24.04.

Significant progress!
In order to connect to the 6Ghz network I must issue “sudo iw reg set US” prior to a connection attempt. Once connected to the 6Ghz network I can then switch between 2.4Ghz, 5Ghz, and 6Ghz networks without any issues. This remains true until I reboot.
I verified Regulatory Domain setting prior to switching to 6Ghz. Attempted to connect....Connection failed.

I conducted a diff between the /etc/netplan/<6Ghz.yaml> file after connection failed, to the same file after it connected. There are no changes in the file, and there is only one 6Ghz .yaml file.
I rebooted system several times to confirm the routine, results are repeatable.
So now I remain puzzled. Why would Netplan, NetworkManager, WPA_Supplicant not pull the current regulatory domain setting? Where is it pulling it from? Is it set in multiple places?
