I am new in Ubuntu and I had a big trouble with wifi. My ubuntu 12.10 doesn't detect my wifi card and I can't toggle the "activate wireless" option on the tasks bar (it is grey). I searched for drivers to make it work, but nothing worked for me. Can anyone give me a hand? Many thanks in advanced!

did you tried Addtional Drivers in ubuntu? search for it in dash. If it is unable to get the driver. Post result of lcpci, lshw -c network and rfkill list all –  Web-E Nov 22 '12 at 17:05
    
Hi, additional controllers tab is in blank. The result of lspci: pastebin.com/Cqe6BA11 The result of lshw -c network: pastebin.com/q0BuC1VY The result of rfkill list all: pastebin.com/wXw3XiDw Thanks for your feedback! –  Pato7 Nov 22 '12 at 20:54
    
Need some more info. Can you post result of lsmod? also make sure the the hardware switch for wi-fi is on. –  Web-E Nov 23 '12 at 4:43
    
Well, there is the result of lsmod: pastebin.com/07dTBfpV –  Pato7 Nov 23 '12 at 13:20

I almost created a new thread in ubuntuforums, but my wifi goes well now. That was: I entered the wifi configuration through a browser and I saw my wifi key was encrypted as WPA-PSK, I changed it to WPA2-PSK and it worked. The strange thing is that after all that I went to "edit network connections" in Ubuntu and I saw that the wifi password was marked as "personal WPA WPA2". I don't know why didn't worked before if Ubuntu accepts "WPA and WPA2". Anyways, thank you much for your interest solving my question, Web-E. ;) –  Pato7 Nov 24 '12 at 18:58
