My house was wired with cat5 wiring when it was built. When I remove the phone jack face plates, I see a total of 8 wires (4 pairs): 4 wires go to the phone jack and 4 wires are not attached to anything. I now want to create a wired home network. I would like each faceplate to have jacks for ethernet and telephone (2 line phone). Is this possible with the 8 wires total that I have? Someone told me that having internet and phone running thru the same cat5 wires would create possible connection losses for the internet and/or phone. Is this true? Thanks in advance for your reply.
