Are you saying you bought a longer cable and it does not work?  But it worked at the shop?

The maximum length for cat 5 cable is 100m, so it's not a length issue.  My guess is that it a connector issue.

Did you have an older cable that was shorter?  Does it still work?  BTW, RJ-45 is the connector, and cat 5 is the cable.

Are you sure they didn't sell you a crossover cable ? ?
Either way i'd have taken it back by now...
