|You didn't have to capitalize modem|
You do becasueit is a hybrid word.
... and whats weird about agreeing with you. It;s not going to work, you need a cable MODEM. Nothing,much else you can say.
Btw, what I was referring to is a combo modem/router... I do know the difference.
I'm glad about that, although what difference it makes to the question I have no idea. As soon as you mention MODEM, whether it a a stand alone unit or a combination unit you have to get the one designed for the job. If you even the slightest idea of how a MODEM works and what it does you would have no need to ask the question.
