AT&T U-verse Installation Manual

Having Trouble?
Many issues can be resolved in three simple steps:
1. Check your connections.
Verify that cables and cords on all devices are connected as specified in step 1. Cables usually make an
audible click when secure. If connections are secure and you are still unable to connect to the Internet,
try another phone jack. If you have AT&T voice service, make sure the phone jack has a dial tone.
2. Power down, power up.
Shut down your computer and unplug the black power adapter and any other devices from the back
of the gateway. Wait 15 seconds and then plug devices back in, making sure the gateway's Power
light is on. You should see a solid green Power light indicating a successful power connection (if the
light is not on, try another power outlet). Then turn your computer back on.
Important: When you power down, you will temporarily lose your AT&T U-verse® TV service,
your TV/DVR connection, and your phone service (if you have AT&T U-verse Voice
3. Wait for blinking indicator lights.
Wait for blinking indicator lights to turn solid green (may take up to two minutes), then attempt to
access the Internet.
Specific issues
I have a home security system, health alarm, or water
meter monitor.
You will need special installation assistance. Call 1.800.288.2020
to schedule an appointment with an AT&T U-verse service
technician or call your monitoring provider. Additional charges
will apply for professional installation services from an AT&T
U-verse service technician.
My power indicator light turns amber during the
power-up sequence.
Don't worry. This is a normal part of the power-up sequence —
just remember not to unplug the power adapter or green data
cable when the light is still amber. At the end of the sequence,
the Broadband and Service indicator lights will be solid green.
