i managed to get wireless on the ubuntu live cd with the help of Bcm43xx firmware thing easy no probs just installed it and it could then see the wireless but it wont work for knoppix 5.0 live cd. how do i get it to work? do i have to use the ndiswrapper thing. if i do where do i find the windows driver?

i have windows xp installed on the laptop and am running knoppix 5.0
also the wirless card is BCM4306 802.11b/g Wireless LAN Controller
