  • Solid White: The router is connected and is online.
  • Fast Blinking Green: Connected and waiting to be activated.
  • Solid Red with WPS light Off: The unit is overheating. You should move it to an open, flat space that is not enclosed to help cool it down.
  • Solid Red with WPS light Red: The unit has a hardware issue. A reboot should fix it, but if not then you may need a replacement. 
  • Fast Blinking Red: There is a network service issue that requires attention. Rebooting your unit should resolve the issue. If this still happens after a restart then you need to contact AT&T and ask them to check your service.

  • Fast Blinking Green: Factory reset is ongoing, please wait for a few minutes.
