I am about to upgrade my home network (one Mac and one PC that share a cable modem) to wireless. And, I go to thinking, does any one make a device that would allow me to make my cable itself wireless. I would like to put a tv and a computer in a room that does have a cable jack in it currently and before I cut a hole in the wall and run a wire for the cable into that room (because if I am going to do that I may as well just run a wire for the cable modem as well). Does such a creature exist??? (If not is it because the bandwidth is too great to send it wirelessly?) Any help will be very greatly appreciated!!!
