Asus AC-53 Nano Not Recognizing 5 Ghz

Hey Guys,
So I needed to get a 5 Ghz adapter due to the operation of my microwave disrupting wireless communication, something that has been a HUGE pain when it comes to competitive matches. My father went out to best buy and got an AC-53 Nano from Asus. While I definitely appreciate Asus' status as a motherboard manufacturer, I've been having some ridiculous problems with this network adapter.

My main issue is that, although the adapter recognizes the 5 Ghz network, it ALWAYS says "can't connect to this network" when I attempt to switch to 5 Ghz. I've also tried running it via 2.4 Ghz, but have received EXTREMELY slow speeds, although other adapters seem to get completely fine bandwidth, so it's not the location of my PC that's the problem. Also, it IS able to connect to the 5 Ghz network, but that requires me to mess around with a crap ton of network modes, which end up failing me a few hours later.

WHAT I'VE TRIED:
Restarting the Router
Changing DNS
Reinstalling/Rolling Back Drivers
Using the Adapter on a Different PC

All help would be greatly appreciated.
Thanks,
Noah

A lot of those portable wifi adapters don't actually run at full speed because they are trying to conserve power, and they also save on size by having small antennae. There is also a lot of stuff that can block the signal in a traditional desktop. On top of that, 5 Ghz has a much shorter range than 2.4 Ghz. Have you considered using a powerline adapter? It might give you slightly higher ping, but it would be stable.
