昨天安装了 debian 发现只能使用有线网卡上网，无线无法使用，用lsmod看也挂载了RT73的模式，但是dmesg后发现

用桌面工具也搜不到无线网，手工加入也是上不了
ifup wlan0显示
Ignoring unknown interface wlan0=wlan0

iwlist wlan0 scanning
显示网卡没有启动

这里有点晕菜了,后来发现应该是驱动的问题

下边说说解决的过程
我下载的的debian5.08 i386 DVD 第一张盘
安装后并无iwlist之类的命令，要自己安
aptitude install frimware-iwlwifi wireless-tools
安完后
再安装雷凌网卡的驱动包就OK了
aptitude install firmware-ralink
然后就看到nm-applet搜出了无线信号
问题解决了
