I purchased a new system Dell inspirion15 with ubuntu 12.04 OS. Everything was fine, then suddenly my wifi connection went off.

I do not see the signal strength on the wifi symbol nor any options for available networks which are present. The Fn+F2 option switches on/off the bluetooth but no effect on the wifi. I do not have any other external option for wifi settings.

I have tried the following:

$ rfkill list

soft blocked :no
hard blocked:no

$ rm -r ~/.config/ ~/.cache/

and restarted my system but no use.

$ sudo /etc/init.d/network-manager restart

no use either.

Hoping for some suggestions.

Copy and paste this command in the terminal (ctrl+alt+t)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.tar.gz in your home folder with wireless information so we can see the condition of your wireless at this time and the Mac address, WPA key and WEP key are removed for your security,paste contents of the wireless-info.tar.gz file as a zip file at pastebin.com.
