I also found out that my asus usb AC-68 could not find samsung galaxy s20+ 5Ghz hotspot with the included drivers, so i went through alot of different drivers, that support realtek 8814AU chipset, and i finally found one that worked.
Also it uses channal 149(155), i think its USA, and im from Denmark.
Now i just need to try alot of different drivers for my Netgear Nighthawk A7000 😀 , since same problem.
Oh and btw, windows tends to revert the drivers back to the newest one after reboot, so disable that.
Maybe it will help someone.
