HP/Compaq nc6320 laptop - Broadcom wireless LAN card (BCM430)

freshly installed Back Track 5 the other day. the card does not even appear to be recognizable - as in zero wireless capabilities.

this laptop is a triple boot with Windows 7, Kubuntu 11.10 and Back Track 5. the wireless card works without issue within Windows 7 and Kubuntu 11.10.

i am very much a novice, so i have no idea what the next step would be.

just fyi, the built-in ethernet adapter works perfectly and without issue, so i can still get updates when hard wired.
