@mdbartel Sorry to hear that you are having trouble with the Internet. We’ll help you resolve the issues.
You may try to reboot the AT&T modem first, with the pcWRT router disconnected. Then reboot and reconnect the pcWRT router. Let us know if this helps restore the Internet.
BTW, what is the model of your AT&T modem? When you lose Internet, does it go away completely or does it slow down? If the problem re-occurs, please send a screenshot of the Status page and the Internet Settings page to [email protected]. Thanks!
