Life was great with my DIR-615 and Motorola SurfBoard SB-5100 cable modem, but my D-Link refuses to recognize the Internet signal from the Thomson. The Comcast guy spent an hour trying to get it to work, but I'm stuck watching MLB.tv on a 24" monitor in a stiff office chair in my study, instead of on a 47" LCD in my living room. How can I force the DIR-615 to accept the Thomson ACG905? If you advise me to check settings or manually change them, please do not "assume" that I know how to access those settings. Rather, PLEASE give me a few hints. THANK YOU!
