Please [edit] your question and add output of lspci -knn | grep Net -A2 terminal command. — Pilot6, Jan 24 '16 at 10:33
There is no built-in Wi-Fi module. Do you ask about a USB dongle? — Pilot6, Jan 24 '16 at 10:52
You should have mentioned this before. Then please add output of lsusb. — Pilot6, Jan 24 '16 at 16:51

Check out that the wireless is not disabled by the physical hardware switch. In this case run the following command, to check whether the wireless is soft blocked or hard blocked:-

himanshu_code@ubuntu15:~$ sudo rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: hp-wifi: Wireless LAN
Soft blocked: no
Hard blocked: no
2: hp-bluetooth: Bluetooth
Soft blocked: no
Hard blocked: no

Check whether the wifi is soft blocked or hard blocked, then run the following command:

 himanshu_code@ubuntu15:~$ sudo rfkill unblock <identity>

in my case it's 1

 himanshu_code@ubuntu15:~$ sudo rfkill unblock 1

Restart the system.
