"Can't connect to this network" - 5Ghz Network

[Wok City]

So I have just completed my new build and I am reusing my WiFi network card from old build which is (https://www.asus.com/au/Networking/PCEAC68/). On my old build I had no issues connecting to either the 2.4GHz or 5GHz I always used the 5GHz as the speed was much faster for myself. Now on this new build I have downloaded and installed the drivers for the adaptor and I am only able to connect to the 2.4GHz connection. When I type in my password for the 5GHz, it does it's loading thing for about a second or two, then it decides to disappear and reappear which I find weird (The list of WiFi options when you right click the WiFi icon bottom right of Windows) then I get the message "Can't connect to this network".

 

I've tried going back a version for the drivers, I've uninstalled and reinstalled neither of these has worked. 

 

My new build is running Windows 10 Pro, Asus X470-F Motherboard, Ryzen 2700X, Asus PCEAC68.

My old build was Windows 10 Home? (I think), i7 3770, ASRock Extreme 4 Motherboard, Asus PCEAC68.

 

Edit. Also might be worth mention this is my router (https://www.asus.com/au/Networking/RTAC68U/)

 

So I'm not sure why I could connect to 5GHz on all build and now I can't on this new build.

 

Any help, is very very much appreciated.

I found after wiping and reinstalling my wifi drivers that it actually seemed to conflict with what I believe were Window's own wireless drivers making the 5GHz band unusable (I have the same wifi card) I uninstalled the Asus drivers and just left it at that, and it seems to work perfectly fine without it. Unfortunately I cant help trouble shoot anymore as I shrunk motherboard sizes and now that card is on a shelf for the next build.

This is probably a noob question, but if I uninstall the Asus drivers I can't connect to the internet at all as I have no WiFi icon in the bottom right to click and connect to a network. There is only the Ethernet/LAN icon or w/e it is with a cross as I am unable to connect via Ethernet. Where can I find Windows 10 WiFi drivers?
