I have Realtek RTL8723BE Wireless LAN. I am successfully connected to a network and doing works for minutes. Suddenly I noticed after few minutes that not a single page is opening, showing resolving host or something like that, but I am still connected to the network. But when I am disconnecting and reconnecting again to the same network it works fine again for few minutes and the same issue again and again, but my LAN connection is stable. Please Help me out.
I am using Ubuntu 15.04 32 bit
Sayan Dutta, I also faced the same problem. But i manage to solve this by adding a file in system folder. Process is given below.
Download the following file from Dropbox and unzip the zip file. https://www.dropbox.com/s/lhk02dxj1vdei6d/rtl8723be.zip?dl=0
Then open the terminal by pressing Ctrl+Alt+T and run following command
gksudo nautilus
hit Enter and give the password.
Then a window will appear, then navigate to "/etc/modprobe.d"
Copy the extracted file and paste in the folder.
Then you have to restart the system and then your problem will be solved.
Install the driver this way. Run in terminal
sudo apt-get install git build-essential
git clone https://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
And reboot
