In Ubuntu help (12.10) it just tells me to go to 'menu'. I can't find 'menu' and so therefore I can't connect to my wifi. I'm running Ubuntu 12.10 off of a usb and I don't know how to connect to the internet.
Firstly, goto " System Settings" on the taskbar. Next, click on network, and then, you should see "Wireless". Click on it and slide from off to on at the top right hand corner.
