Learn about your extender LED light

The light on the front of your AT&T All-Fi Extender tells you what it’s doing and how it’s performing.

Use your notification light to find out what’s going on with your All-Fi Extender™. Want all the details? Review the AirTies 4971 lights (PDF, 268KB)

If your notification light is:

  • Alternate green/red (flashing): Your extender is connected but too far from your Wi-Fi gateway or another extender. Move it closer to your gateway or another extender.
  • Red (slow blink): Your extender has lost connection or couldn’t connect through Wi-Fi Protected Setup (WPS). Check for a loose or damaged Ethernet connection, then press the red reset button. Or, press the WPS button again.
  • Red (solid): Your extender couldn’t connect to the paired gateway. Or it’s connected to an unsupported third-party router or smart device by Ethernet. Disconnect all Ethernet connections. Then, connect the extender by Ethernet to your gateway.

If your notification light is:

  • Alternate green/red (pulsing): Your extender is connected but too far from your All-Fi Hub or another extender. Move it closer to your hub or another extender.
  • Red (slow pulse): Your extender is having connection issues. Check for a loose, damaged, or disconnected Ethernet cable. Or, make sure it’s in Wi-Fi range of your hub or another extender.
  • Red (solid): Your extender couldn’t pair with your hub. It could be connected to a third-party router. Reset your extender and connect it directly to your hub using an Ethernet cable. If you’re still having issues, your Extended Wi-Fi service may not be active. If the light remains red, contact us.
