AT&T Extended Wi-Fi Coverage FAQ

AT&T Extended Wi-Fi Coverage expands Wi-Fi® coverage in your home. It includes: Don’t have Smart Home Manager yet? Manage your network using Smart Home Manager from your computer. Or, download the app from the Apple App store or Google Play store.

Both Wi-Fi Extenders and the All-Fi Boosters expand the Wi-Fi coverage in your home or business.

When you get your new Smart Wi-Fi Extender or All-Fi Booster, we suggest you remove any older AirTies extenders you may be using. The older extenders won’t work well with your new one.

You can remove compatible AT&T Smart Wi-Fi Extenders (models 4971, 4921, or 4920) from the Network Hardware list in Smart Home Manager when the extender’s offline. Here’s how:

Devices tend to switch connection between your Wi-Fi® gateway and extenders. They can also switch connection between your All-Fi Hub and boosters. In general, devices connect to the one that provides the best connection, not necessarily the one that’s closest. Here’s how to see devices connected to your extender:

Ethernet backhaul is a direct connection between your Wi-Fi gateway and extenders. It’s also is a direct connection between your All-Fi Hub and boosters. This lets them communicate without using Wi-Fi. This can help overcome certain Wi-Fi issues and further extend the range of your Wi-Fi coverage by using Ethernet links between extenders.

The Smart Wi-Fi Extenders and All-Fi Boosters included with Extended Wi-Fi Coverage service support Ethernet backhaul. To use Ethernet backhaul, just connect Ethernet (Cat 5E or later) cables between your Wi-Fi gateway and extender or All-Fi Hub and booster. Set up and pairing will automatically happen if not previously paired.

Important: This won’t work with third-party routers unless they’re in bridge or passthrough mode. If the third-party router has been assigned a static IP address, the first three sets of numbers must match your Wi-Fi gateway or All-Fi Hub (for example, 192.168.1.XXX). The XXX has to be an open IP address number (0-253) and can't be used by any other devices on the home network.
