I am trying to get my old Airport Extreme to be used as a backup for Time Machine on my Mac. I want it to join my new Mesh Wi-Fi System. Light keeps blinking yellow. Are there any instructions on how to do this?
Using Applications -> Utilities -> Airport Utility
Configure the Airport Extreme so it is in "Bridge Mode" which turns off its router functions.
If possible just plug the Airport Extreme WAN port (ethernet port with a circle icon) to your Mesh network router.
If not possible, then using the Airport Utility teach the Airport Extreme the name of the Mesh network SSID and password.
YOu have an Airport Utility.App in your Utilities folder—
Flashing amber Startup is complete, but the base station has detected a condition that requires your attention.
