Internet connection

Receiving error 

NET::ERR_CERT_VALIDITY_TOO_LONG After power outage and loss of internet. Modem and router show we should have connection but all internet devices in house are not working. Seems to be a timeout issue related to Comcast servers

Good Morning, @user_xqeius! Thank you so much for taking the time to reach out to us here on the Xfinity Forums! I am very sorry to hear about the experience with your service after a power interruption, it certainly is not what we want for our customers. I know it has been a few days, are you still unable to access the Internet? If so, have you completed any troubleshooting steps?
