I bought a pre-installed Ubuntu laptop with 12.04. It used to detect the wireless connections. But due to some problems in my WiFi, I inserted the net cable directly into the laptop. Since then, There is no option for wireless connections.

when I used rfkill list all it showed me that bluetooth and wireless is hardblocked. When I pressed the keyboard button for WiFi, the hardblock turns off for both bluetooth and wireless. In short, the Wifi key turns Bluetooth and Wifi on and off. But still it doesn't show any wireless connection. Nothing...

Please help. Tried all the methods on ubuntu forums like rfkill unblock all , sudo wireless service start , But it doesn't work.

It is safe to run it was written by me and some good friends it will help diagnose your wireless issue. Paste this command in a terminal wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script It will download a script and create a file named (wireless-info.txt, or wireless-info.txt.tar.gz) in your home folder paste the contents of the file here pastebin.com then paste the link back here. No internet then go to this link for running the script without internet. [url]ubuntuforums.org/showpost.php?p=12350385[/url] –  Wild Man Oct 20 '13 at 23:05
