I've had my VIP722 receiver hooked up to broadband for months now with no issues... this morniing when I woke up there was an error message on my HOME COMPUTER that said IP CONFLICT... then I noticed my VIP722 was showing NOT CONNECTED to broadband... hmmm... nothing changed!!! How did this IP conflict just pop up? I reset everything... VIP722, router, modem, PC..... same thing... any ideas?
