We have 3 desktop computers, the main one downstairs is hooked directly into the cable via a modem, then I have a wireless router hooked from the modem so the 2 computers upstairs can run wireless (also have a wireless signal extender upstairs).
Question: We want to take one of the wireless computers upstairs and hook it directly into the cable connection in that room, because it just isn't getting a good enough sign to run wireless.
If we get a splitter so we can run one cable to the TV, can we run another to the computer, and what do we need to hook the cable to the computer with (router? modem? something else? since the cable does not hook directly into the computer).
