noob420,
I've always placed the .inf and the .sys driver files in my home directory, then pointed internet/network configuration to the .inf file. This always worked with my Compaq laptop which uses the a broadcom driver. However, it seems there's been a number of drivers built into the newer system, thus, network configuration asks if you want to use the built in one or the windows one. Try one, then if it doesn't work, try the other.
If the system still can't find ndiswrapper (which is installed in PCLinuxOS 2008.08 by default if you have a wireless adapter), you might try installing the 2.6.38.8-pclos3 kernel, reboot, then try again. That is what worked for me.
