Hi! To start with: I am a complete newbie to Linux and Ubuntu, so please bear with me if I don or say anything stupid.
My problem is: I have upgraded ubuntu 12.10 to ubuntu 13.04. Before that I have used 12.10 with wubi and have then migrated it to a partition with the help of a script. Now 13.04 is up and running with one exception:
The wifi connection doesn't work. It doesn't show my wifi network and I can't enable wifi connections. I have tried many things which I have found here in the forum especially in that thread:
http://ubuntuforums.org/showthread.php?t=2143840
But either I don't get what they mean or it doesn't work for me. To give you as much information as possible I have just entered the same in terminal as the (at least to me) more experienced user in that thread. So I hope it gives you a good overview over the status of my failing wifi connection.

It seems to me, that i don't have the same problem as the one which is described in the quoted thread. Especially the entry I get under >>iwconfig is different
and worries me... Is there anyone who can help? Thank you very much in advance!
