Question about Cat5 Cable

[cchen]

I bought 2 100ft cables recently. When I plug it into my computer and the ethernet port, the light on the nic comes on but I am unable to connect to the network and also to the Internet. when i switch cables to the original cable, it works fine....

what could be wrong with these 2 cables?

It is either a xover or a straight thru. Look at the wiring scheme of the "original" and compare to the new one.

If they are identical, then its just possible its a bad cable. I have ran into that with pre-manufactured (pretty high ratio compared to make it yourselfs).

If both of your cables are not working then there is a chance that you are mixing crossover and straight through cables. there are 8 wires inside the cable and all are of different color. Please check your original cable (one that works). You can figure out if it crossover or straight through. If all the pins on the connector on both ends of the is connected to the wire of same color it's straight through cable other wise it's crossover.

yea
i think the cable that i got was wired incorrectly
if i cut off the ends and get some rj45 connectors and a crimper, i should be able to rewire the cable right?

Yep, it's easy. Do it at school all the time .

hmm
i seem to have forgotten the wiring scheme for a straight thru

can someone help me out?
