Windows 10: Can't connect to 5ghz wifi

There is no 5 GHz Wifi option in my laptop, but I can connect to it in my other device. I tried everything and look for the solution in this community before but all of them cannot solve my problem.


This is my Wifi card: Intel Dual Band Wireless AC-3168

5GHz Wifi

Hello. I want to connect to 5GHz wifi, but its not showing up in the connection list. I've done a bit of research and my laptop should be able to connect to the 5GHz band.

 

5ghz wifi not showing windows 10

I just got a new modem/router and it has a 2.4ghz and 5ghz wifi connections...Only the 2.4ghz shows in the wifi list while the 5ghz isn't showing at all. My computer's network card does support the 5ghz and I know the 5ghz is working because I can connect to it from other devices...just not my desktop computer.

EDIT: I've attempted updating network driver, also resetting network in the settings menu. Both hasn't worked.
