Asus RT N56U
When the 2.4GHz radio is enabled, the 5GHz radio does not function when both are set to US country code.
Steps to reproduce:
Set up radio 1 and radio 2 with US country codes.
Reboot.
Only the 2.4GHz radio will work.
If you disable the 2.4GHz and reboot, the 5GHz will work.
Any additional info you thinks is important:
Tried all workarounds listed.

Workaround:
Set the 2.4GHz radio country code to World (00) and reboot. Leave the 5GHz on US. Now both radios work.
