PIII and Apple Airport Express

[ergo]

Hi

I know a few people have managed to get their PIII connectly wirelessly using Apple's Aiport Express.

I have tried this myself with no luck

I thoguht that I would need to set the Aiport unit to connect to an existing wireless network (and thus enable me to contact it from another PC wirelessly) but from what I can see, if this option is selected it disables the WAN Ethernet port and so the connection to the PIII is severed. Is this right

I am connecting to it via XP not a Mac and the config tools are different for Windows machines, I do not know if it is not a n option or if I am doing something wrong

Thanks
