Comment 33 for bug 1240940

I have tried the following on several kernels (under 12.04 and 14.04) and so far it has worked well :

sudo apt-get install linux-headers-generic build-essential git
    # needed only if you don't have yet that package
git clone http://github.com/lwfinger/rtl8723be
    # needed only if you don't have yet downloaded rtl8723be

cd rtl8723be
git checkout 604aa9058fb9e5bb1cf571c99989d081f8fc8b9
make clean
make
sudo make install
sudo modprobe rtl8723be
echo "options rtl8723be fwlps=0" | sudo tee /etc/modprobe.d/rtl8723be.conf
