Ok grrrr... so we have had Comcast now for years and until recently no issues. We got a new modem/router a few months ago and now I can’t get Wires-X to pass the port check. I have UPnP selected and during the port check it claims success on all 6 ports, I have also opened those ports on my PC. What seems to be the issue is the WAN it address call comes back with an error of 400 bad response. I spent well over an hour on the phone with the useless Comcast Hindi tech who loved to talk in circles and did absolutely nothing. I tried to open the ports in the router as well but that sends me to my Comcast account page, and after digging there a bit I found the port forward feature but it would not accept the changes... it just froze on the wait a minute we are updating your device screen. I also tried turning off the advanced security (as per Comcast’s recommendation when using port forwarding) just to receive the same wait screen that keeps me waiting. I don’t know what modem this is exactly but it looks like one of those small electric potpourri fan things you get at WalMart for $20. Any ideas on how to fix this?
