Install RTL8723BE wireless NIC Driver in Ubuntu 12.04

Source: Internet
Author: User

I bought a new toshiba satellite m50-A.

Ubuntu 12.04 is installed, but no Nic is found.

Lspci-vnn: Check the NIC model. It is Realtek's [10ec: b723]. google it, corresponding to rtl8723be.

Then make driver

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

Result compilation error, found http://askubuntu.com/questions/428873/errors-running-make-on-wifi-kernel-module

This is a problem with the kernel version.

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

Restart. OK
