I have installed Ubuntu 14.04 LTS on my laptop.

Under the networking menu at the top, it is not showing any WiFi options.

How can I get Wifi working in Ubuntu 14.04 LTS?

I have a Broadcom BCM4311 WLAN card.

  • Just Suspend the system and then resume back in. This surprisingly solves the wifi issue! Worked for me [ubuntu 14.04 LTS x64 on Asus laptop] Jul 23, 2014 at 14:54

For Broadcom BCM4311,

sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source broadcom-sta-dkms

sudo apt-get install b43-fwcutter firmware-b43-installer

See here https://help.ubuntu.com/community/BroadcomSTA(Wireless)

  • That worked like a charm :) Apr 23, 2014 at 8:09
  • My son's laptop finally worked with this.

  • When the WiFi stopped working for some reason reinstalling the b43 packages did the trick for me: sudo apt-get install --reinstall b43-fwcutter firmware-b43-installer.

you can go to

settings> Software and updates > additional drivers

you can get most of wireless/Graphics drivers. You can install any 3rd party driver software you require. Hope that helps!

    this helped. open source driver was choosen, but this only works with proprietary. after choosing proprietary driver in this dialog, wifi worked again. thanks

If you're using a Broadcom (BCM43xx) wireless network card like me, this might help.

I connected the laptop using a cable and ran:

sudo apt-get install firmware-b43-installer   

to install the driver and then rebooted.

(It would be helpful to add your network card to the question.)


Maybe you faced a problem like me Network indicator disappeared.

A solution that works for me is here:


Simply speaking, try nm-applet at first, if you take back WiFi indicator, then add nm-applet to Default applications for LXSession.
