My modem used to be in the office where I have 2 desktop computers, DSL was coming in on the phone line. Now with Spectrum, the modem is near the big screen TV, and the router is in the office. I have one cat5 cable running between the 2. This is a base 10 arrangement, which only uses 2 pair. I want to add my Netflix to the TV. Can I or is there a way to use the other two pair to go from my router to my Blue ray player?
