Which uses two pairs: 1-2 and 3-6 (the numbers are the pins on
the RJ45 plug).
A crossed cable does this:
1-3
2-6
3-1
6-2

This last assertion is incorrect. 100Mb/s Ethernet can *not* work on longer
cables.
Two things to check with your scenario:
1. The cross-connection cable may be too *short*. This is not a joke;
check it out. Try to use a longer cable (15m or more). At 100Mb/s,
the high frequencies tend to generate inhibitively high crosstalk
when the cable is very short.
2. Disable auto-negotiation (for half/full duplex and 10/100). Fix
the stations on 100/FDX (or 100/HDX if you wish). Auto-negotiation
tends to break in too many cases; piggyback may be one of them.
Good luck
