Does an internet modem use the same cable as a TV?

I recently moved my computer setup to a different place in my basement. My internet modem is still located in the room upstairs and I want to move it downstairs to my new area so i can use ethernet. The modem has a coax cable going into it, providing the internet access. My new spot has a cable just like it, which I use for my HD DVR cable box. If I were to just unplug the cable from the box and plug it into the modem would it work for internet access?

generally yes the cable modem prefers rg6 just like HD video does but it works on rg59 if that is all you have.

Make sure your splitters are rated for data some of the older splitters will cause your modem to not work well.

The basement is the absolute worst place to put the device if you plan to connect to it via wireless in the rest of the house but you have little choice if you cannot get ethernet run to the other location.

hmmm. Could I just buy a really long ethernet cable, hook it up to the modem and run it to the computer in the basement? Or would it be slower because it's such a long cable?

Nope speed in no way is dependent on length. Cat5e cable can go 100 meter and run 1g speeds. It doesn't matter if the cable is 10m or 100m it will always be able to run 1g. If you try to exceed the 100m limit by much it does not run slower it just completely fails to work at all.
