intel wifi link 5100无线问题
我的本是thinkpad t400, intel wifi link 5100无线网卡，内核 2.6.27，系统 fedora 9 ,但是无线网卡总是有问题：＃ifup wlan0
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan0 ; Invalid argument.
Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.
正在决定 wlan0 的 IP 信息...
就是网线网卡的指示灯亮了，但无法正常工作，总提示有上面的错误，selinux也报错。。
以下是一些基本信息：
＃iwconfig wlan0

不知哪位达人有解决的经验。。非常感激！！ 我也有这个问题。现在正用最新驱动测试呢。 2.6.27内核下，把selinux禁用，用networkmanager管理就行了
但2.6.25内核下还是不行。
