Cat 5e vs. cat 6.  Cat 6 doesn't work in some situations?!

My son is at college.  they have LAN connector to network at his desk.

I sent him a cat 6 jumper cable to go from the lan jack to his PC.  he said it didn't work.  he had to use a cat5e cable.  I tested the cat 6 cable and it passes for continuity / straight through, like the cat5e he used.

he said someone else in the dorm said the same thing - cat 6 wouldn't work for them. had to use cat 5e.

I thought cat6 is interchangeable with cat 5e jumpers for a 10 / 100 network?  That anywhere you'd use a 5e jumper, you could use cat 6?  No?!

Cat 5, Cat5e and Cat6 are compatible.  Differences are in quality of copper wire, number of twists etc. to eliminate crosstalk.  All these cables use 4 pairs to send/receive.  Cat5e and Cat6 can handle typically 100/1000Mbps.  Make sure you are using the patch cable version and not a cross-over version.

For a 10/100 network that is absolutely correct.  On some gig networks all 4 pair are used while on 10/100, only 2 pair are used.  

Is it possible that the cat5 cable that they are using is not a straight-through cable?  Maybe the college used a non-standard termination to force you to buy one of theirs.
