Note: If you already have a phone connected to your AT&T U-verse Voice service and want
to add a second line, skip to “Adding a second line” under step 3.
Power down your computer and existing modem by removing the power cord from the electrical outlet.
Disconnect the data cable from the DSL port in your existing modem and from the dual-port filter. This cable
will not be used in the new setup. Plug one end of the new provided green data cable into the DSL port on
the new Wireless Gateway and plug the other end into the wall jack.
Disconnect the Ethernet cable from the Ethernet port on your existing modem and from the Ethernet
port on your computer or router. This cable will not be used in the new setup. If you’ll be using a wired
connection from your computer to the Gateway, plug one end of the provided yellow Ethernet cable into the
Ethernet port on the new Wireless Gateway and plug the other end into the Ethernet port on your computer.
Now that you have disconnected your old modem or router, you may set that equipment aside, as it will no
longer be needed.
Remove the sticker covering the Power port. Connect the provided Battery Backup Unit (BBU) to the
Wireless Gateway’s Power port. Plug the BBU into a standard electrical outlet.
Connect one end of your phone cable into the Wireless Gateway’s phone line 1 and 2 port, and connect the
other end to a standard phone or cordless base station.
