5GHz wifi networks not showing on Ubuntu 22.04 (mt7921e)

Setup:Dual boot Ubuntu 22.04.3 LTS and Windows 10.Motherboard: MSI B550M PRO-VDH WiFi

The motherboard has an inbuilt wifi module and they specify the following on the producer's website:

  • Supports Wi-Fi 802.11 a/b/g/n/ac, dual band (2.4GHz, 5GHz) up to 433 Mbps speed.
  • LAN Realtek® RTL8111HN Gigabit LAN
  • Wi-Fi / Bluetooth Wi-Fi AC, Bluetooth 4.2

The wifi module works as intended on Windows 10, connecting to a 5GHz network without issues.On Ubuntu I have observed that the 5GHz network appears very rarely (I switch between windows and linux frequently), most of the time connecting only to my 2.4GHz network. Most of the time can't see, nor connect to 5GHz networks.

I tried upgrading the kernel to the latest release with current being

uname -r

6.7.1-060701-generic

I have disabled

  • Windows Fast Startup
  • Sleep
  • Hybernate
  • Secure Boot in BIOS

However I still suspect that there is some interference between the two operating systems.
