I am trying connect a printer to the network, but the available cable does not reach. I have one of these connectors which are basically two female rj-45 jacks back-to-back which I want to use to add an extension cable. I've used the regular telephone version of these connectors many times to join two phone cords together without problems, but every time I try to use the rj-45 version, it NEVER works.
What am I doing wrong? I've tested both cables and they're fine. Both cables are straight through cables - do I need to change this? I've searched high and low and not found anything regarding network cables connected in series.
