Let's help get you connected to the internet, @twv879!


We recommend that you restart your gateway. Doing so can help refresh your connection. To restart your equipment manually, follow these steps:

  1. Unplug the power cord from the back of your gateway or modem. If you have: 
    • An internal battery backup, remove it
    • DSL, unplug the phone cord from your modem or gateway
  2. Wait 20 seconds.
  3. Put the internal battery back in if you have one. 
  4. Plug the power cord back in. If you have DSL service, reconnect the phone cord.
  5. Wait up to 10 minutes for the gateway or modem to restart and your Broadband light to turn solid green.

Additional troubleshooting can be done by using the sign in option in our AT&T Internet Support article.
