![Gentoo 上的 Centrino Wireless-N 2230](https://linux22.com/image/1354962/Gentoo%20%E4%B8%8A%E7%9A%84%20Centrino%20Wireless-N%202230.png)
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 :

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。
