I need to link a router to a socket downstairs by RJ45 cable. My ***** builder was asked to run a double phone line in the wall of an extension but only ran a 6-wire phone wire (to a double socket). He also failed to leave any space in the wall for me to get another cable down (no conduit
).
Can I use the 6-wire phone cable to connect to an RJ45 socket, retaining an extension phone on the remaining wires? As far as I can see I need 4 wires for the RJ45 and 3 for the extension phone, so it looks like no, but will it be possible, and will I suffer on speed as a result?
