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

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.
