When troubleshooting wireless it's important that the system is fully updated. Using wired internet access please run
and reboot if necessary.
sudo apt-get update
sudo apt-get dist-upgrade
If you still have the problem search thoroughly and see if it has alreadly been answered. Chances are more than good that is has.
If you don't find anything relevant please download and run the wireless script it can be ran by copying and pasting the command below in the terminal (ctrl+alt+t) opens the terminal:
It will download a script and create a file named (wireless-info.txt, or wireless-info.txt.tar.gz)depending on the size of the file and it will be placed in your home folder. The wireless information will help to diagnose your wireless issue, the Mac address, WPA key and WEP key are removed for your security, then reply back, click on the paper clip and attach the (wireless-info.txt, or wireless-info.txt.tar.gz) file as a zip file or using code tags as described in step one below.
wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script
