I'm using a Dell Inspiron laptop with Ubuntu 12.10. I am new to Linux.

I am typing this from a wired connection because I cannot find how to set up my wireless router. When I first installed 12.10 it gave me a men in the install wizard to set up WiFi but when I restarted it turned off. I cannot figure out how to get wireless, or to see available wireless routers.

WiFi is on and works with my iPad but I literally cannot find the place to enable WiFi on this OS. What am I doing wrong?

It might be the nm-applet hanging. I've had problems with it listing the available networks right after login. The solution is to kill and restart it.

sudo killall nm-applet && nm-applet &

Make sure that your wifi hardware switch is on or not. It is either F2 or F12 or near to it. Once the switch is enabled, there is a small fan-like applet on the top panel (Gnome Network Manager), fourth from the right.

enter image description here

Click on it and if there is no tick mark on the option 'Enable Wireless', enable it. Wait till your wifi connection name appears.
