Xfinity Stream no working on ANY device (wifi or via PC over ethernet)

I spent 3 frustrating hours being transferred from one department to another...going through the same steps I had previously. For the past 3 days, the Xfinity stream has not working on any device (IOS via the App over WiFi or a PC directly plugged into the router via Ethernet). There are no other problems with accessing any websites, but on all devices trying to watch live tv gives the same message: "Connect to in-home WiFi to watch". Essentially the router is not recognizing that I'm on the home network...which leads me to believe it's a router issue. I saw previously a lot of people with this issue and had called and asked for a deep background account database refresh...but 24 hours later...same problem.
