I bought an inspiron 5520 here in Thailand and the seller had installed windows. I only use my laptop for education so I have decided to go with Ubuntu. i noticed that the internal wifi card is not working. How can I fix the laptop and get the Wi-Fi working? Thanks. I am a newbee. ;)

If you are connected to internet via some other adapter wired or wireless, run in terminal

sudo apt-get install bcmwl-kernel-source

and the internal adapter should work.

Or go to System Settings -> Software & Updates -> Additional Drivers

and install the driver.

Both methods do the same thing.
