WiFi adapter not showing 5ghz network?

[Sithex]

I just purchased this device: https://www.amazon.com/gp/product/B01G51FBF6/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1#customerReviews

And I can only see my 2.4ghz network. When I type "netsh wlan show drivers" I get this:
Radio types supported : 802.11n 802.11g 802.11b 802.11ac 802.11n 802.11a

I believe this means my wifi card supports 2.4ghz and 5ghz.

When I go to my router config it says under 2.4ghz "Default: 802.11n/b/g 2.4 GHz"
and under 5ghz "802.11n/ac 5GHz". I really don't understand what to do, or maybe im wrong and my card doesn't support it? The model for my router isL: 5268AC, its an default router given to me ATT

Okay so I fixed it. Heres what I did:
1. go to device manager
2. go to Network adapters
3. go to your wifi adapter mine is called "Edimax EW-7833UAC AC1750"
4. go to properties
5. go to advanced tab
6. go down to "Wireless Mode"
7. I chose IEEE 802.11a/n/ac since that's what my router supported, note I had to scroll up in the menu I didnt realize this for a few minutes
