先确定你的模块的问题吧。

看是真的没模块啊，看是只能自己去编译了。

Atheros AR8162 我也没有驱动模块

木有驱动……需要自己下载编译了……而且更新内核的话需要重新编译……

[pkuphy]

去 http://linuxwireless.org/download/compat-wireless-2.6/ 下载compat-wireless-2012-07-03.tar.bz2（最新版本好像不支持 alx）

解压，cd 进解压出来的目录

代码： 全选

./scripts/driver-select alx
make
sudo make install
modeprobe alx

Good luck! ^_^
