I have Comcast and I can't get my Buffalo wireless router to work. It worked fine in my apartment. I just moved into a new house and Comcast gave me a new Motorola modem when they came to hook up the cable. I've hooked it up with the cable going into the modem, then a line going to the router, then the computer like the Buffalo user guide says. Then I tried a line going from the modem to the computer and another line going from the modem to the router, like the Motorola Modem guide said. Basically I've tried every combination from both user guides and I keep getting "Page can not be displayed" when I try to connect to the Internet.
The only way it works is if I just have a line from the modem to the computer and nothing else hooked up.
