Try this set up:

1 ethernet router connected to the internet which is then connected to a linksys wifi router. this router has 4 wired ports(ethernet) and a wifi. Just follow the set up procedure in the box and it should be up and running in no time.

OR...

use windows xp network set up wizard that should do it. You can set up Internet Connection Sharing using the wizard.
I assume you are familiar so you know how to run the network wizard. Click the my Network Places Icon, experiment with it. what you want is to set up a home network. There are options there, just choose the one that suits your needs.
