My ASUS USB-AC53 Nano claims to have 802.11ac wireless mode option but only has b, g and n. This is frustrating as I’ve recently found that the reason for my slow internet only on my PC is because of 2.4Ghz, and I cannot use 5Ghz with b, g or n. Is Win11 hiding 5Ghz from me or am I missing something? I’ve literally wasted hours of my life waiting for crap to load and trying to find the solution. Anything would help.

Full story:

When I go to Device Manager, I cannot find the preferred band setting, therefore can’t use 5Ghz. I’ve found that to have 5Ghz, I need 802.11ac but I don’t have it.
