Any ideas on how I can check where the fault lies in the wiring? BTW, both the jacks that the computers are connected to are funtioning properly.
If you can use a "long phone wire" between the computers, what kind of cable are use using?? Standard ethernet type wiring requires an 8-wire connection, or possibly the leftmost 4 wires of the 8 wire RJ45 connector. If you use the existing wiring, you're not getting a "direct" connection, you're piggy backing onto the telephone company's connection with all sorts of electrical "things" in the way. Plus you're only getting the inside 4 wires of the 8-wire connection??
I really believe you need to start over after reading up on what is actually required for this connection. I got the "cable guy" to install 8 wire CAT 5 cable in my house when we added a couple of extra cable jacks, installed a cheap ethernet hub and we're working great.
