Yes you can get a second cable modem but that incurs a second monthly fee. Most of us will opt for a router.

Alright, I'm 95% sure that I can't do this but... I have cable internet downstairs on that and there is a convenient cable jack in my upstairs study where I have another computer. Is there any way to use that jack for internet and not have to wire crap upstairs or use a wireless router?
