  • In laptop i have also windows and the wireless works, so I think that this is not the problem but it's true that whe i go to the folder networks or like that the "button" is disabled and I can't turn it on, ubuntu doesn't let me to turn it on

Please refer to the askubuntu page shown below, it should be helpful, at least somewhat. As long as you are ok with terminal. Good luck.

Qualcomm Atheros AR9485 Wireless Network Adapter not working on Ubuntu 13.10

  • Can you find out if the wireless card is compatible with 14.04? I think that might be the problem. If so, I would just get a new card that fits into your PC. If you do get a new card, make sure it works with your Ubuntu version. Another problem could be your kernel. Find out the linux kernel that you have and see if the card works with the kernel, too.
