Wireless Problems With DHCP

Hi,

I am troubleshooting a wireless network where all laptops with built in
wireless work 100%, as soon as a laptop with a PCMCI wireless card
tries to connect, it is not getting an IP from the DHCP server.

The server is Win2k3 SBS and is the only DHCP on the network. AP is
Netgear, PCMCIA cards are Gigabyte.

I have manipulated the AP in every way possible and still no luck.
Laptops with built in Wireless ALWAYS connect and Laptops with wireless
cards NEVER connect.

If I, for example, connect wired connection to the laptops with the
wireless cards, they immediately obtain an IP from the DHCP on both LAN
and WLAN. After that happens I can disconnect the cable and network
keeps functioning fine. If I then "Repair" the connection using the
Windows repair function, it again can't get an IP.

I also have a wireless network at home and have tested all the PCMCIA
cards on my network and they all work 100%. The only difference between
the two networks is that the AP I use at home is set as the DHCP
server.

What couls be causing this bizarre problem?

Thanks in advance :)
