I have installed Linux Mint-17 on my laptop. However, i am unable to connect to any wireless network. A red dot is flashed under the network icon on the bottom-right corner(near clock).
I referred the link:- Connecting Linux Mint to WiFi network which suggested to execute:-
sudo apt-get install b43-fwcutter firmware-b43-installer
So, i connected by cellphone through USB-tethering and successfully executed this command. However, the red dot still persists and i am unable to connect to wireless network.
The laptop has a realtek8723BE pci network adapter.
When i execute iwconfig, the output is:-
lo no wireless extensions. eth0 no wireless extensions.
How should i connect to wireless network ??
