@ComcastJohnN I was directed to you by Louise at Xfinity Support out of Knoxville, TN after she was unable to resolve my issue. Like many other posters to the community forum, I have an Arris Surfboard SBG7580-AC gateway that I am unable to connect to the internet reliably. The device has been provisioned with its HFC MAC ID and I have checked through the router's admin that IP filtering is not enabled. Like other forum posters, I can access IPv6 sites (Google, Facebook, Apple) but cannot access IPv4 sites. Can you or anyone else on this forum provide assistance? Thanks in advance for your help.
