4921 & 4920 - AT&T Smart Wi-Fi Extender Lights
Learn about your Wi-Fi extender LED lights
What should I do if my status light is solid red during pairing?
Connect an Ethernet cable from any of the ports on the back of your Wi-Fi extender directly to your Wi-Fi gateway. If you get a solid white light, the pairing process has completed. You can disconnect the Ethernet cable and place the extender in a new location.
If you get a solid red light:
- Be sure you’re not connecting through a 3rd party router
- Make sure there aren’t any smart devices connected by Ethernet to your extender
- Be sure you have Extended Wi-Fi Coverage service. Check your plan
