Setting up Wifi on Ubuntu 12.04 Server via command line (yeah, finally some technical stuff )

Problem: Setting up a wireless adapter on Ubuntu server 12.04 LTS via CLI isn’t THAT easy. Plug’n’Play doesn’t simply work. Good thing there is Google. And a lot of helpful sites. Target: Insert the stick (or boot with it) and connect automaticly to the preferred network This is not a tutorial. And it’s realy not for the uninitiated. It’s more like a short reminder for me, or people who have a basic idea what’s happening here…
