You can get the drivers from GitHub.

Get a temporary internet connection, then open a terminal and do:

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

Your wifi should now be working.

    I followed your answer and install this driver. But the problem with me is when sit near to the wifi router i get connected but when i get into other room my wifi get disconnected and my system doesn't show any available wifi. I have another laptop with ubuntu in the same room and it works perfect but that one has intel wireless. Is there any way i can get wifi signals with realtek ? Earlier on this laptop was installed windows 10 and it was working fine so it is not a hardware problem. – user433546 Nov 23 '15 at 6:46
