英特尔迅驰无线 N 1000 无法在联想 Z560 上运行

英特尔迅驰无线 N 1000 无法在联想 Z560 上运行

我将 Ubuntu 11.04 升级到 11.10,但 Wifi 停止工作了。我有一台联想 Z560,它配备了英特尔迅驰无线-N 1000。我搜索了各种有类似问题的帖子以寻求解决方案,但没有成功。wlan0 甚至没有显示在 rfkill 中。请帮我找到解决方案。

下面我给出了各种调试命令的输出。提前致谢。

答案1

不幸的是,N-1000 系列在 2.6 内核上无法正常工作。目前最好的解决方法是禁用卡的无线 N 连接并仅在 b/g 上运行。这不是最理想的,但它有效。

尝试做

sudo modprobe -r iwlagn 
sudo modprobe 11n_disable50=1 11n_disable=1

为了使更改永久生效,请将以下行添加到 /etc/modprobe.d/iwlagn.conf 文件中:

options iwlagn 11n_disable50=1 11n_disable=1

答案2

我不知道解决这个问题的具体方法,但就我朋友的情况而言,他需要输入“rfkill block all && rfkill unblock all”,然后他的 wlan0 就会像魔术一样出现!
