Right not I have my home entertainment pc wired into the back of my wireless router. My setup has a splitter from the wall out. One going to the TV tuner in the pc and the other going into the cable modem. But as of last night, I can only get a signal to the cable modem if I plug it directly into the cable outlet in the wall. If I try it via the splitter, I don't get signal. Obviously, Cox cables internet signal leaves something to be desired. So other than trying to get a new splitter which may or may not fix the problem or having a tech person come out, would it be better to just get a wireless usb for the home pc and then relocate the cable modem and wireless router to another cable outlet in the house? I am also connecting a laptop via the wireless router. I really don't even use internet access on the home pc other than retrieving information while in the Media Center interface.
