I'm having some issues with a new box of 1000' cat5e cable and was wondering if anyone on here could provide some advice. I know this isn't exactly a Linux question but it's general networking and I figured it would be in the same ballpark for many of you :)

Anywhoo, a lot of the patch cables I am making is failing to light up the 'link' lights when I plug them into various devices. I have made a couple successful ones that work but the majority of them are a huge headache and are not working. The weird part is we have two cat5 network cable testers here, both of them confirm that all my lines match up and that both ends of the cable are identical (one of the devices even gives me an accurate reading of the cable lengh). Still though I have issues plugging these into devices. At this point I'm wondering if there's something wrong with the cable, or wrong with the RJ45 end pieces, or a weird combination of both. Do Cat5e cables require a different rating/class/whatever of RJ45 ends than cat5 cables? I don't seem to have this issue when I'm making traditional cat5 patch cable...

Thanks in advance for any pointers.
