Install your replacement Wi-Fi gateway

Learn how to disconnect your old Wi-Fi gateway and install your new one.

Ready, set, swap

It should take about 20 minutes to set up your new Wi-Fi® gateway and get online. Before you start, keep in mind:
  • You won't have internet or voice service during this process. You may want to print a copy of these instructions before starting.
  • You’ll need your sign-in info. Keep your AT&T Access ID and password or your account number and 4-digit passcode handy.
  • Your replacement gateway doesn’t include a battery backup. If you need a new one, you can purchase it from a third-party manufacturer or retailer. For more info, check out att.com/batterybackup.

Connect your new gateway

Tip: Take a photo of your existing setup. That way, you have a reference for connecting your new gateway.
  1. Place your new gateway next to your old one.
  2. Transfer your existing connections one at a time to the new gateway.
  3. Plug the new power cord into your new gateway and then into an electrical outlet. While the new gateway powers up, don’t unplug the green data cable or the power cable. It can permanently damage your gateway and delay your activation. When the Service and Broadband lights go from flashing to solid green, you’re ready to go.
If you have U-verse TV, make sure you restart your DVR and all other TV receivers after the Service light turns solid green. Just press and hold the power button on each receiver for 10 seconds.

Set up your Wi-Fi

  1. Locate the yellow sticker on your new gateway. It has your Wi-Fi network name (SSID) and password.
  2. On a computer or device you want to connect to the internet, go to the wireless network settings.
  3. Find and select your new Wi-Fi network name and then enter the 12-character password. Your device should connect to the internet.
