My laptop connected over 5GHz wifi in every test except for one: the MT7927 going through a wall with powersaving off. In that test, my laptop connected over 6GHz. I did nothing to influence which band the laptop used, so I think it is fair to let the MT7927 reap the rewards of connecting over 6GHz.
