Not sure this is the right forum but... I'm going to be hooking up an ethernet connection to a friend's TiVO. She does not have a computer or a router and would have no use for either one. But she does have internet service via a Comcast modem. Can the ethernet wire be hooked up directly to an ethernet port in the modem without a router? I"m sure I'm asking a silly question, but I don't know much more than my friend does, but it seems there should be a way to hook it up without installing a router. She had been using dial-up for her connection, but since it was thru Comcast's phone service, it never worked properly and now she has no guide info.
