I have ubuntu 11.10, I have moved into a new house with shared Sky Broadband and I would like to know how to detect the wireless automatically as I am not sure I can get all the information required to configure it myself as the person in charge of the internet is a bit of a grumpy old ** basically. I have the password (network key?) I think (!), I just need Ubuntu to detect the wireless automatically (and connect to it automatically whenever I start my computer). Im not very computer literate, so if you answer this question please take that into consideration before speaking another language! Thanks!
If your networks card is configured and running Ubuntu already does that. On your taskbar you can see an icon wich contains all the networks Ubuntu detects.
If you like you can try tools to better see the networks avaiable to you.
Gnome-network is one of those tools, Wicd is another.
