Ok SO i have built a CAT5 straight thorugh cable (well actually its 2 cables), both the same length, about 35 feet give or take a few inches, I used top quality cable ( I know its good I pinched it from work) and finished the ends with the standard RJ45 plug, both securely fitted.
So whats the problem ?
Well the cable is to link my Broadband router upstairs to the Cable Modem situated downstairs, and it doesnt work..., I mean the first cable I built, I thought fair enough might be a faulty build, so I built a second one (now you why i said it was 2 cables) and that one (same length etc) doesnt work.
I have tested both the cables with a CAT5 pulse tester and both cables test all 8 pins fine on a constant check.
At the moment I am using a shorter cable length say about 15ft long and all is OK, thing is the cable modem is in a place that looks unslightly, hence the longer cable so it can go with the TV\Video equipment
SO here's what happens.
I plug in the cable to Router and Modem, Router doesnt show a light on the port, then it does, then it doesnt etc etc.
So i plugged the cable into my laptop and then into the Lan socket of the router, same thing, the light goes on and off and the laptop shows "Acquiring network address....." then " Network cable unplugged, then "Acquiring network address....." etc etc etc
So next step was to put a Hub in line so the cable ends in a Hub, same thing hub light comes on then goes off then comes on...etc etc.
I am so at a loss , im under the 100M limit for CAT5, the cable tests fine with a test tool, all I can think of is that there is insufficient power across the cable to maintain a constant signal when supplied from a Hub or Router.
Ideas appreciated...
