HA501 how to...

Hello, I have just installed knoppix 3.8 into my laptop but the module for my wireless card is not included. However I've found the driver on the internet. Can anyone help me on the installation? This is my first time. Thanks. PS. Is there a web site where I can get more info on this subject?
Thanks

this is the basic run, very basic...

you download the package, and hopefully it could be installed using the package manager...

Package manager? What do You mean? What I have to do?
