I am a newbie to ubuntu. I have installed Ubuntu 12.04 freshly onto my system and since then have been desperately been trying to get it to detect my wifi and connect to it. I have tried several approaches but none of them seem to have worked so far. Can someone please advise me on this? When I type in iwconfig i get :-

eth0 no wireless extensions

lo no wireless extensions

sudo lshw -C network gives :-

Hi Avinash. It's not giving any output –  Sparky Feb 22 '14 at 17:59
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 Feb 22 '14 at 19:48
