Also, you have to test the buttons and light signals to work effectively on the device. Ensure that the power cable is working along with the other wirings that connect your PC with the router.

#4 Remove Firewall

The router must be suspicious of a particular website, due to which it is not responding. It creates a firewall against the network and locks it for unauthorized users. If you have your AT&T WiFi connected but not working, the firewall might be responsible for the same.


These are under the control of the admin or the moderator. You only need to log into the router’s settings to remove the firewall. However, you will disable the device’s shield protecting you from hackers. Make sure to look into the user manual to know more about this feature. Also, don’t forget to reconnect wifi after making any changes to your device. For additional help you can refer to our guide on changing wifi on Feit Electric app to keep your home secure.
