Connect your new Gateway

Take a quick photo of your current connections for reference since your setup might be different from above.

Place your Gateways side by side.

Transfer your existing connections one at a time to your new Gateway, except for the power supply.

Plug the new power supply into your new Gateway and then into an electrical outlet (not controlled by a light switch).

Wait about 15 minutes for your Gateway to power up and complete the start-up process.

Using your Wi-Fi®

Your Wi-Fi settings will automatically transfer from your old Gateway to the new one.

Your wireless devices will connect to the Gateway again when the process is complete.

Open the Smart Home Manager app to confirm your Wi-Fi settings have transferred.

Since settings will not match the new Gateway’s defaults, use the enclosed yellow sticker to update your Wi-Fi info and apply to the new Gateway.

Return your old equipment

Bring your equipment to The UPS Store® or FedEx® Office in a sturdy bag, tote, or open box.

Have your 9-digit account number handy (noted on your packing slip or bill).
Your equipment will be scanned, packed, labeled, and returned to AT&T.
The carrier will give you a receipt, and your return will be immediately noted to your account. Retain the receipt for your records.

Note: We need to receive your equipment within 21 days of your replacement order date to avoid non-return fees ($150).

Troubleshooting

My Internet or Gateway Broadband light doesn’t turn solid green during power up. Check your cable connections.

Check power. Power light on the Wi-Fi Gateway should be green; if not, try another electrical outlet.

Power down , power up. Unplug the power supply from the Gateway. Leave it unplugged for 20 seconds, then plug it back in. Allow up to 15 minutes for lights to turn solid green.

My Gateway Service light (if applicable) doesn’t turn solid green during power up.
Power down, power up. Unplug the power supply from the Gateway. Leave it unplugged for 20 seconds, then plug it back in. Allow up to 15 minutes for lights to turn solid green. If the light is red, power down and power up again. If it is still red, contact us for technical support.

My Gateway Power light is amber.
Do not unplug the Gateway; this is a normal part of the process.

I can’t connect after swapping my Wi-Fi Gateway.
Try rebooting or reconnecting your connected devices. Or, in the Smart Home
Manager app, select Help > Restore Wi-Fi Settings. (Any special configurations like port and IP settings will have to be set up manually.)

If you have an AT&T Wi-Fi Extender, in Smart Home Manager, go to **Network

Network Hardware > Add Extender**

My TV Receivers are not responding. (For U-verse® TV)
Check all your wired connections and confirm Service light is solid green. Hold the TV Receiver’s Power button down for 10 seconds and release, then wait 5 minutes.

My AT &T Home Phone doesn’t have a dial tone. (For digital phone service) Make sure your phone cable is plugged into the Phone Line port on the Wi-Fi Gateway.

Additional information
