How to know your Wi-Fi Extender is working

Solid green = Paired and functioning

Use AT&T Smart Home Manager app to see if Extender is on your network (visible in the Devices section or through the Assistant).


  Your AT&T Internet service needs to be active.

Flashing red = Out of range Move Extender closer to Gateway or another connected Extender.

Solid red = Not paired Try to pair with WPS or use included Ethernet cable to connect Extender to Gateway and pair manually. See alternate setup method.

Blinking amber = Software updates Don’t move the Extender or turn it off.

Check all cables and cords to ensure connection.

Unplug power from Gateway for 15 seconds, then plug back in. Do the same with Extender. It may take 10 minutes for Gateway or Extender to reboot.

    Your Ethernet cable may be connected directly to the Gateway in place of the WPS method for pairing.
  3.  PLACE Unplug Extender from outlet. Move it (40 ft., two walls max., and, for best results place it up off the floor) between Gateway and area you want a stronger signal. Plug Extender into outlet and wait for GREEN light
