How to enable Broadcom Wireless Driver by Terminal on 16.04 LTS?

Question

I have just installed ubuntu 16.04 LTS. When I choose try before installing, wifi was not working. So I activated wifi driver by Software & Updates >> Additional Drivers and It was working while installing (and try before installing).

But after installing, I am not able to activate by same procedure. When I enable and input my password, it does nothing.

Output of lspci --vvnn | grep -A 9 Network

-- Select Using Broadcom 802.11 Linux STA Wireless driver source from ....

-- When I insert password, nothing happen, It still selected Do not use this device

@Pilot6 it's already disabled and I already checked http://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers (but it did not solve my problem) — Madan Bhandari, Jul 31 '16 at 18:08
@Pilot6 I just installed and not able to enable wireless driver by GUI. — Madan Bhandari, Jul 31 '16 at 18:12
What did you install? Your output shows that you did not. You need to install bcmwl-kernel-source. And there is no need to activate anything in GUI. — Pilot6, Jul 31 '16 at 18:15
Run sudo apt install bcmwl-kernel-source. Nothing else is needed. — Pilot6, Jul 31 '16 at 18:21
@Pilot6 how can I install this without internet ? It was working fine while using before installing (try mode)\ — Madan Bhandari, Jul 31 '16 at 18:23
There is a link to this question in the manual I linked before. It seems you did not bother to read it carefully. http://askubuntu.com/a/626653/167850 — Pilot6, Jul 31 '16 at 18:26
@Pilot6 Thanks buddy :) It's solved now :) I am new to Linux, sometimes it's hard to understand easy problem too. — Madan Bhandari, Jul 31 '16 at 18:38
