If there's an outage, hang tight. We're working to get you back online.
If there's not an outage, go to step 2.
Make sure all AT&T cables are securely connected. Also:
Verify any device connected to your phone line has a DSL filter and is securely connected.
Confirm the green data cable connects the filter to the broadband gateway port.
Check to make sure the phone port goes to the phone line, and the DSL line goes into the DSL filter.
Revert any recent change to your wires, splitters, or faceplates. Or, check out different service options.
Confirm the advanced gateway setting (Broadband, then Configuration, then Broadband Override) is set to Auto. Or, if you have a 5268AC gateway, go to Settings, then Broadband, then Link Configuration and see if it’s set to Automatic Ethernet/DSL.
Press and release the red Reset button on the back of your gateway to reboot it. This can take up to 10 minutes.
Watch the broadband or service light. When you see a solid green light, close and reopen your browser.
