New user having troubles connecting wirelessly with new Ver.

Similar questions have been asked, and maybe even the same question, but I'm new to this, and have no clue what's going on. I still haven't been able to install anything because I don't know what my password is, but that's a whole other question (which while not in the correct forrum, feel free to answer). My question however is this: I am using knoppix 3.6, and all I have to do is turn it on and I automatically connect to the wireless network, I don't have to do anything, but now with knoppix 4.0.2 DVD I can't get online no matter what programs I've tried running, and I don't know how to check, but I don't think it even detects my WIFI card. Any and all help would be amazing because aside from no Internet 4.0.2 seems to be heaps better.
