Enabling WLAN card in Linux Ubuntu 14.04

Today I just installed Ubuntu 14.04 in my Lenovo G510 and found that the laptop's WLAN card is not detected by Ubuntu.

Here is a quick way to enable the WLAN card :

1. Connect to a temporary LAN connection
2. Open a terminal
3. Type in the following command
          

sudo apt-get install bcmwl-kernel-source

4. Disconnect from the temporary connection

5. Give a reboot 




Done . Your WLAN card will work like a charm !!
