MacBook Pro running XP Pro - Airport problem

I installed XP Pro using bootcamp. I can connect to my Airport network but Airport does not supply in an IP address, subnetmask, router address.
XP Pro is configured to use DHCP and yes, TCP/IP protocol is installed.

As a result, I cannot access other computers on my LAN or the Internet.
When I use an ethernet cable connection to Airport, all is well. I get
an IP address, subnetmask, router address and Web connection.

Has anybody got this to work?
TIA

This is a known problem with MBP running Xp.

Some are blaming a certain type of wireless network card.
I had the same thing, but I got rid of windows coz it reminded me why i switched to osx
