Only four Ethernet cables are available for use.
I've been considering setting up a dedicated ethernet connection for my PC to fully utilize my 50MB/s speed. Instead of buying a new cable, I thought about swapping the jack on an old phone cable since it connects directly to the modem. The only issue is that they only have four cables available, wouldn't that be fine?
Using a Cat5 or higher cable allows you to achieve up to 100Mbps with four wires, while for greater speeds you must use all eight wires and a Cat5e or better cable.
also if its a old phone cable there is good chance that it might not handle high speeds well. Phone cables aren't made for high bandwidth.
In theory, it might function at 100 mbps provided the connections are correctly made: arrange the four wires in positions 1,2, 3 and 6—pair 1 and 2 for sending data, pair 3 and 6 for receiving (or vice versa). To achieve 1 gigabit per second, all eight wires need to be present. While it could work over a short range, standard setups require the pairs to twist together with specific twists per inch, and the cables must be precise. Typical home phone cables don’t twist the wire pairs well and are thinner, making it hard to secure RJ45 connectors properly. Perhaps using an Ethernet port and plugging in a regular Ethernet cable would be more practical.
If the cable isn't twisted pair, it won't function properly over a long distance.
