After installing Ubuntu 14.04 the wifi icon and option just disappeared. I have tried to reboot it and searching the settings for it, but it does not let me connect to a wifi connection in any way. The only way to connect to the internet is with a wired connection. So how can I fix this and is this a bug or something that has to do with the version? I installed it on a Dell Inspiron 910 mini netbook.

First you have to stop network manager from background:
sudo service network-manager stop
Remove file on /var/lib/NetworkManager/NetworkManager.state path:
sudo rm /var/lib/NetworkManager/NetworkManager.state
Start network manager back:
sudo service network-manager start

Please do what is in the accepted answer in the link below so we may see the information needed to help diagnose the issue. http://askubuntu.com/questions/425155/my-wireless-wifi-connection-does-not-work-what-can-i-do – Wild Man Jun 02 '14 at 15:10

For newer versions of ubuntu using systemd rather than upstart, the commands to start and stop a the network manager service are `systemctl stop network-manager` and `systemctl start network-manager`. (Note that `systemctl` does not need to be run with `sudo`, as it will prompt you for sudo access itself.) – AJMansfield Oct 01 '15 at 18:08

I was facing this very same issue. Please note that wireless was working fine all this time, its just the missing icon.
Here is what worked for me. Unity -> Startup Applications - and check "Indicator Application" (if its not already checked.) Next install following two packages: indicator-applet and indicator-network.
sudo apt-get install indicator-applet indicator-network
I am using Ubuntu 14.04 64bit on Dell Inspiron 1564.

Thanks! Can't imagine why they thought it was a good idea to remove the icons. – Jake Jul 06 '15 at 06:25
