5Ghz not working

[Moyg]

My 5Ghz isn’t working I have it on split bands it says password is wrong and I’ve tried changing it and trying the password and still says password wrong but the 2.4 ghz works fine and I use the same password for both

On the WiFi page where you set the password you can click the little eye icon on the right so you can see what the password is, is it exactly what you expect/what you're entering? You don't have caps lock enabled when you're entering the password on your mobile/PC for example?
