Have you made any progress on using this card?

Mine shows up in system profile, but doesn't report a driver. Connects to the router but won't receive DHCP, shows full reception in the Airport menu, but won't connect to anything!

It appears to be working, but it's not.

My hardware:
G31m-es2l, e5200, GeForce 8400GS video, and the WN311B wireless card. Running 10.6.1 perfectly with sound and QE/CI, just won't connect to the network.

Any suggestions from anyone?
