I installed Ubuntu using a wired connection but now I am unable to connect via wireless network. I can't find any wireless network connection and I think the problem is that Ubuntu turns my wireless adapter off, and the shortcut button (Pressing Fn and F2) won't work in Ubuntu.

When I start up Windows again I can see that the wireless adapter is switched off and I can back set it on by pressing these buttons (it opens a window where I can turn on wifi as well l as bluetooth, probably an application from Packard Bell).

I already installed ubuntu once with the wireless network and it worked fine.

Is there a wireless hardware switch? What brand an model machine you have? –  Mitch Apr 10 '13 at 19:07

what does sudo rfkill list show? what does sudo lshw -C network show? –  Rinzwind Apr 10 '13 at 19:09
    
This is what I get with these commandos: docs.google.com/file/d/0B9l7HVKLk_TJa1dlQ05XXzZyVVE/… I have a Packard Bell lx86. There is no "hardware switch", it is a shortcut button on my keyboard. –  Stein Apr 11 '13 at 12:21
    
This is better I think, this shows the lshw -C network: docs.google.com/file/d/0B9l7HVKLk_TJMGlvMktkeXdXS00/… The previous didn't showed the wireless connection. –  Stein Apr 11 '13 at 12:33

In the upper-right corner you should have an icon dedicated to the wireless connection. Right click on it and click "turn on wireless".

The problem with this is that I don't have a wireless connection icon. This is probably because ubuntu thinks that I don't have a wireless adapter. –  Stein Apr 11 '13 at 12:22
    
Btw, I do see all this for my bluetooth connection. So I can switch my bluetooth receiver on and off like I can do in Windows... –  Stein Apr 11 '13 at 12:23
