All 5,GHz bands stopped broadcasting and are greyed out on my Nighthawk AX6600
Had no power problems and the unit is on a UPS, all of a sudden all three 5 GHz just disappeared. The 2.4 is the only band working. Go into the program and all 5GHz bands are greyed out. Any sugges...

Check the wifi button, press it for 5 seconds then release to see if the radios were shut off.
Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.
Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

Thanks for that reply.
The router is mounted 6 and a half feet up so the wireless button couldn't have been accidentally pushed.
Nothing has been done to the setup in a very long time so don't have a clue what happened.
I tried to stream a program on my TV which is set to the 5 bands and got a 'could not connect alert.
I have a password for the router that would be very hard to crack so don't know what happened.
Will bag it tonight and do a reset in the morning too so if that works.
Thanks again.
