Obviously a step by step guide would be very helpful please as I'm new to this inputting code lark.

I had a wireless connection when I installed ubuntu 12.10 from the cd once it installed it suggested there was 126 updates so I installed those and my wireless connection has stopped.

I've tried looking at other posts but find that I end going round in circles, what I'm after is the answer in a step be step format without having go around the houses looking at a thousand other posts with similar problems.

Below is what popped up in the terminal hopefully theres some kind person out there that understands what the problem is....
