Have a router/modem combo that had ran fine for the past year. Bought the Q90T a month or so ago, just recently noticed that anytime I try to connect my tv to the internet, either direct cable or WiFi, It immediately performs a Denial Of Service against my modem. This drops internet connection to anything connected to the modem/router (regardless of connection type), and per Xfinity (my ISP) who was at my house today trying to troubleshoot, completely locks up the modem altogether / stops communicating with them. Any ideas?
