Ubuntu12.04安装RTL8723BE无线网卡驱动

买了个新本 toshiba satellite m50-A.

安装了 Ubuntu 12.04，但是系统没有发现网卡。

lspci -vnn 看网卡型号. 是Realtek 的 [10ec:b723].google一下，对应rtl8723be。

然后make 驱动

sudo apt-get install linux-headers-generic build-essential git
git clone http://github.com/lwfinger/rtl8723be
cd rtl8723be
make
sudo make install
sudo modprobe rtl8723be

结果编译错误，搜到http://askubuntu.com/questions/428873/errors-running-make-on-wifi-kernel-module

说是kernel版本的问题。

The most recent version has been modified to correctly compile on kernel version 3.14; you are using 3.8.0-36. It is necessary to get an earlier version of the package. Please open a terminal and try:

cd rtl8723be
make clean
git checkout 604aa9058fb9e5bb1cf571c99989d081f8fc8b9
make
sudo make install
sudo modprobe rtl8723be

重启。OK
