As you mentioned that you are using ubuntu 14.04 so do the following steps to correct the problem:
- Open Software & Updates and go to Additional Divers
- Install the fitting driver from there.
- Restart your system
- Now your WiFi will definitely work and it will show the WiFi signals (within its range) also.
iwconfig
in terminal and paste what it returns here?
