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.

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
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.
