I had to reinstall Ubuntu 12.04 LTS on my HP Compaq nc8230. Everything went fine, as before. I did a restart based on "197 Updates", then while carrying the laptop, I pressed the key labeled 2

enter image description here

After this the wireless LAN was deactivated and I'm not able to activate it anymore; not with the key and not with the option on the upper right corner of my desktop. Now the sign looks like an empty triangle.

iwconfig tells me that my interface 'eth1' has an wlan extension, which I already knew it had, because I used it before. But I have no clue how to activate it again...

Can anyone suggest a fix?

I had a problem very similar to this with my laptop. After a recent installation of Ubuntu, my wifi adapter just totally shut off for some reason. I fixed it by changing the bios settings back to default. Not sure what I did to it, but try there first. I was dual booting that the time, and the wifi worked under windows 7, so it may be a driver issue. Also check to see if you are in Airplane mode, ya I forgot about checking that once and was really annoyed for a few minutes. Hope you find an answer!
