My modem comes into my house on the first floor and I have a Cat5 cable running from it through the walls upstairs to my wireless router. I need the router upstairs in order to get a hardline to my XBox. However, I need a hard line for a device that is next to my modem downstairs. I really do not want to run a line from my router upstairs back down the wall to the device downstairs.
Is there a way to split the signal from the modem to provide a line running to my router and another line running to a device?
