I'm having a problem with my cable modem (with Comcast); just recently my modem has been experiencing a sort of "lock-up" where the Power, Pc-Link, and Cable lights stop flashing and my internet connection dies. I have to reset my modem, then another lock-up occurs within an hour or so. I've contacted Comcast and they said it must be a hardware problem. Is it possible for this problem to be fixed or should I just buy a Linksys BEFCMU10? Thanks for the help.
