PC Finds 5GhZ network but can't connect

[GraciousBassist]

I have recently encountered a problem connecting to my modem/router's 5GhZ network. I have been connected to it in the past but now my computer will find the network but will not complete the connection to it. I have other devices that are connected and working on the 5GhZ network, and my computer seems to work fine on the 2.4GhZ now.

My computer has an Atheros/Qualcomm AR938x Wireless Network Adapter
My Modem/Router is a Technicolor DPC341T stock from Xfinity
I am running Windows 10

Any help would be greatly appreciated.
