笔记本：TOSHIBA 5200
系统：KUBUNTU5.1
设备：LINKSYS wireless-g USB网卡
ndiswrapper1.9安装好后，没有出错信息，用ndiswrapper -l,可以显示设备已经安装成功。下面是命令信息：
william@ubuntu-toshiba:/mnt/win1-2/Drivers/WUSB54Gv4$ sudo iwconfig

eth0 no wireless extensions.

sit0 no wireless extensions.

Warning: Driver for device wlan0 recommend version 18 of Wireless Extension,

到这里表示找到了无线网卡，但没找到MAC我就不明白了。

竟然没找到网络，太。。。。。伤心了。换了NETGEAR54GUSB卡后，也是用同样的模块启动，可以找到网络。
有没有高手或着有经验的网友指教一下。
