Why won't the 5G WiFi work when the 4.2 does?
My router has 4.2G & 5G WiFi. Every device attaches to both of these (1 iPad, 2 Androids, 2 Windows PC's). My MacBook Pro USED to connect to both, but now it will only connect to the 4.2G. I get a "password error" on the 5G.
It USED to work - until I did the last update (High Sierra 10.13.6)
The same password works on every other device. Except the Mac.
The 2 WiFi's are set up the same as WPA2-PSK [AES].
I ran the diagnostics, and it said that there was a conflicting country code.
The time & date are United States. The Apple Store is United States. The Modem is set to United States. And, it works on the 4.2G. So I don't know how that could be the problem.
BUT:
This is what the network report returned. It says: The nearby networks conflict with your current country code (X0) (It would certainly help if this could be copied and pasted...
All the modems are US as expected.
How do I fix this, and why is it ONLY the 5G on 1 device out of 6
Help!
How is that even possible?
