Pair an extender with your AT&T 5G Gateway

1. Using the included power adapter, plug in the 5G Gateway by inserting the power adapter into the DC Power Port and plug the attachment plug into your electrical outlet. When your device is powered on, it automatically searches for and connects to the AT&T mobile broadband network. This will take approximately 2-3 minutes. 

 

Note: For the best experience, place the extender within three feet of the 5G Gateway during setup.
