#2. Troubleshoot your PC

If it is your computer that has the AT&T WiFi not working or AT&T Internet not working issue, you can try troubleshooting your PC to solve the issue. For example:

  1. Turn off your computer, wait 30 seconds, and turn it back on.
  2. Clear your browser cache (temporary Internet files) and clear your browser cookies.
  3. Run your anti-virus and anti-spyware software. Viruses and spyware can deplete your computer’s system resources. Infected computers may generate network traffic without your knowledge causing slow Web surfing/browsing speeds or no web surfing at all.
  4. Disable your firewall temporarily to determine if the firewall is the cause of your problem.

#3. Check your wireless settings

If you’re connecting to the Internet using a wireless connection, you may encounter the Wi-Fi network not found issue. To solve the ATT WiFi not working issue, follow the steps below:

  1. Make sure that the AT&T Wireless Internet is powered on. The Power indicator light should be a steady green if connected to a power outlet (or blinking green if on the back-up battery).
  2. Refresh the network list on the device you are trying to connect.
  3. If the AT&T Wireless Internet network still does not appear and an Ethernet connection is available, log in to the AT&T Wireless Internet Manager (while connected to your AT&T Wireless Internet device), go to Settings > Wi-Fi > Basic, and make sure the Broadcast Network Name (SSID) is enabled.
  4. Restart your AT&T Wireless Internet device by switching the power button to OFF and then back to ON.
  5. Refresh the network list again. If still unable to detect the AT&T Wireless Internet SSID, it may be necessary to perform a device reset to restore factory settings.
To perform a device reset, remove the bottom cover of your AT&T Wireless Internet and using a ballpoint pen, press and hold the RESET button for eight (8) seconds. After the reset, you may log in to the device using the default login attadmin.

Reboot your gateway. If this method doesn’t work, you can perform a factory reset. This will return the gateway to its default settings. Here is the guide:
1.       Note down your Wi-Fi network name (SSID) so you can re-apply it once you have completed the factory reset.
2.       Locate the Reset button on the rear of the gateway, located directly beside the power input.
3.       Press and hold the button for at least 10 seconds. If you release the button sooner than 10 seconds, the gateway will reboot, but will not reset.
4.       After releasing the button, wait until the device reboots and all the status lights on the gateway are lit. If the reboot was successful, the Broadband and Service status lights will be solid green.
