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. Maybe you will find the solution by studying the output.
If the output does not make sense to you it's time to open a new thread. Remember to
- post the results of the wireless script in CODE tags and
- choose a clear and informative title:
"Heeelp, wireless doesn't work": No
"Atheros ABC123 drops connection, Ubuntu 14.04": Yes
