Gentoo 上的 Centrino Wireless-N 2230

我目前在 Thinkpad T430u 上运行 Gentoo，嵌入了 Centrino Wireless-N 2230 卡。问题是，即使使用正确的驱动程序配置和固件，我也无法使用无线网卡。

我已经完成了与该问题最相关的网站： http://wireless.kernel.org/en/users/Drivers/iwlwifi

http://wiki.gentoo.org/wiki/Wifi

但是我无法在 Gentoo 上使用我的无线网卡（它在 Windows 上使用）。

以下是我的会议摘要：

以下是有关 iwlconfig 的 dmesg：

以及有关 wlan0 的 ifconfig/iwconfig ：

wlan0: flags=4099<UP,BROADCAST,MULTICAST>  mtu 1500

wlan0     no wireless extensions.

如果有人有想法？因为我真的迷路了。

基于 Gentoo 的 Sabayon 11 似乎可以毫无问题地支持我的 Asus U32VJ 中的 Centrino Wireless-N 2230 BGN。KDE 下的 Networkmanager 可完成其余工作：

有迹象表明你的司机或多或少是正确的：

lsmod | grep wifi
iwlwifi                57633  1 iwldvm
cfg80211              145999  3 iwlwifi,mac80211,iwldvm

唯一的缺陷是无法通过键盘或网络管理器关闭无线电源。

如果您喜欢 Gentoo，那么您可能会更喜欢 Sabayon。
