Can't connect to 5GHz network (W10)

[dylan.vn]

I have recently encountered a problem connecting to my modem/router's 5GhZ network. I have been connected to it in the past on windows 10 but now my computer will find the network but will not complete the connection to it.

I first get the message "checking network requirements" and after some time it says "Can't connect to network". It doesn't tell me if the password is right or not, even if I type it wrong. 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.

I already tried to remove and install the drivers back and I also tried to use other drivers.
I tried to reboot the router/modem and set it to factory settings but it doesn't help.

My computer has an Netgear A6210 network adapter
My Modem/Router is a b-box3 from Proximus (dutch provider)
I am running Windows 10.

Any help would be greatly appreciated.

"Manage known networks" from within W10 network settings, forget the network and try again. Obviously make sure the password is correct by checking the settings on the router.

Already tried that. :/

Tried changing channels?
