我的无线网卡是Ralink公司的RT2571W芯片网卡。驱动为官网下载。Linux系统为红旗Linux 6.0 sp1版，内核为2.6
在Linux下安装前面所有的步骤都正常，可是在最后一步加载rt73.ko文件的时候总是出错，请高手们能为我指点一下。谢谢了！QQ：6422374
以下是安装全过程：

首先你的驱动安装过程编译就有问题(我用的不是雷凌网站下载的驱动，是开源社区的驱动，雷凌的驱动不支持注入模式)
我的这个编译时也有问题，只要打开文件调整头文件和添加LINUX/TYPE.H
编译就好了，至于编译后挂载问题是由于系统自动挂载了驱动，但是这个驱动没法使用。
查下，网上有好多说这个问题的，修改完重启完就好了，具体改我也忘记了，如果有问题发邮件给我ruixiang_fan@msn.com
安装好后不要用系统自带的图形网络管理软件，如果是没密码的也就算了，如果需要改KEY esssid的话，那个软件会死机的^_^
我一般用命令行
ifconfig  wlan0 up
iwconfig wlan0 essid  youessid
iwconfig wlan0 chanel  you
iwconfig wlan0 key  ****
dhcpcd  wlan0
大体就是这样的，写个脚本也可以呵呵
