G+_Curtis Stone Posted June 28, 2016 Share Posted June 28, 2016 Hey Knowitalls! I've tried my hand at some home networking, running a number of cables between the basement and second floor where we're going to put our new office. I bought a simple combination crimper/tester and, even though I've triple checked everything, it's telling me I have split pairs in all sockets. I even went so far as getting my wife to double check the wiring (painful, but I am colourblind) and it's definitely good. The funny thing is, if I use different patch cables between the outlet upstairs and the tester, the split pairs result changes. Sometimes it's between 1-2 and 3-6, sometimes it just says 3-6 and sometimes it just says 1-2. Is it possible that the tester is just too sensitive to interference and is giving false positives? Each of the patch cables test fine when tested independently. Link to comment Share on other sites More sharing options...
G+_Travis Hershberger Posted June 28, 2016 Share Posted June 28, 2016 Something probably happened in the run between boxes. A Netgear or HP smart switch would give you estimates of where the first problem with the cable is. Link to comment Share on other sites More sharing options...
G+_Curtis Stone Posted June 28, 2016 Author Share Posted June 28, 2016 Can you elaborate on what you mean by "Something happened"? It's not just one cable, the same problem is happening on multiple runs. I know there is a location where the wires come near a power wire. Could that be the source of interference?

G+_Travis Hershberger Posted June 28, 2016 Share Posted June 28, 2016 By something happened, it could be as simple as a cable getting kinked when it was pulled through the wall/conduit. Unless it is running right beside the power cord for an extended length, that shouldn't be an issue. Link to comment Share on other sites More sharing options...
G+_Ben Reese Posted June 28, 2016 Share Posted June 28, 2016 Are you using jacks at one end or just crimped ends on both ends? On a 10/100 network, typically only 1,2,3,6 are used where 1,2 is a pair (orange or green) and 3,6 is a pair (green or orange). If the pairs are just swapped, everything should still function fine but not if the two wires in a pair are swapped (confusing enough?) I'm not sure if Gigabit will still work with a cross-over cable - I'd have to try. Link to comment Share on other sites More sharing options...
G+_Curtis Stone Posted June 29, 2016 Author Share Posted June 29, 2016 Crimped end in the basement, jacks upstairs. The colours and pairs are exactly as you described. I suspect it must be damage in the wire in the wall somewhere or an overly cautious tester. I'm going to test it out in a few days and see if there are any connectivity or throughout limitations Link to comment Share on other sites More sharing options...
