Something very strange going on, run this in terminal

Code: Select all

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

and copy the contents of the wireless-info.txt file that will be created in your home folder and paste into a post using code tags to prevent smilies from popping up
