|I took a working network CAT5 cable cut the end on it and pluged one end into the router and used pins 1,2,3 and 6 and connected to the same pins to this network jack that I own. then took another working cat5 cable from the jack to the computer and it shows network cable unpluged.|
This may be a stupid question but, if you have a 4 pair, Cat5 cable, why are you trying to use only 2 pairs (4 wires)? Are you trying to make 2 connections out of one cable? If you don't have to, don't, use all 4 pairs.
but ya i took a computer only 2 feet from the router and made up a wire using pins 1 2 3 6 and it gives the network cord is unplug. I have two machiens working on this router right now just fine 0 problems at 100mbps
All I can tell you is you have to be wiring it wrong if this is still happening. I've done 2 pair connections when using 25 and/or 50 pair Cat5e cable (typically used for telephones) and also made a number of patch cables this way and I've never had a problem.
