Just curious - if anyone's minds a quick followup...
The cable runs into a splitter-type device, it comes in one side and basically out on the other (not sure why they installed it - this has the ground wire attached to it though). From there it goes into a splitter - one side goes roughly 10 feet to the tv and the other side goes about 12-14 feet to the cable modem.
Now, in the event that I want to add cable tv in the same room with the modem - should I split the cable-tv run off to come up to another jack or can I simply split 'above-ground' at the already installed jack - and would either really matter?
