After a long time, I finally succeeded. Now I want to record the installation process. 1. Preparation 1. download the latest ndiswrapper package, and prepare 2. Prepare the win driver for the wireless network card and find the corresponding inf and sys files. Here are bcmwl5.inf and bcmwl5.sys (xp supported ).
