You need a crossover cable.  You can sometimes buy them at CompUSA or Radio 
Shack.

To make an TIA/EIA-568B (a fairly common/standard pinout) Cat5 crossover 
cable, reverse pins 1 and 3 and 2 and 6.  In other words, it'll look like 
this on one end:

1 white with orange stripe
2 solid orange
3 white with green stripe
4 blue
5 white with blue stripe
6 green
7 white with brown stripe
8 brown

And on the other end it will look like this:

1 white with green stripe
2 green
3 white with orange stripe
4 blue
5 white with blue stripe
6 solid orange
7 white with brown stripe
8 brown
