When troubleshooting wireless, it's important that the system is fully updated. Using a wired internet connection, please run:

sudo apt-get update
sudo apt-get dist-upgrade
and reboot if necessary.

If you still have the issue, please download and run the wireless info script (https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info), which will gather information to help diagnose your system. You can run it using these commands:

wget -N -t 5 -T 10 https://github.com/UbuntuForums/wireless-info/raw/master/wireless-info && \
chmod +x wireless-info && \

This will create the file "wireless-info.txt" at the location it is run from, and depending on its size, an additional archive called "wireless-info.tar.gz", for attaching on the forums. Sensitive information like MAC addresses and WPA/WEP keys are masked automatically.

If you cannot connect to the internet with the affected system, including via a wired connection, go to this link http://ubuntuforums.org/showthread.php?t=2082305&p=12350385&viewfull=1#post12350385 and follow the directions for running the wireless script without an internet connection.

Further details on the script: https://github.com/UbuntuForums/wireless-info

Please study the results carefully, especially regarding the listed wireless network devices (lspci, lsusb, PCMCIA), and search the forums using this information to see if you can solve your issue on your own before starting a new thread.

If 'Broadcom' appears in the output next to '[0280]', please head over to the Broadcom guide (http://ubuntuforums.org/showthread.php?t=2214110).

If you still have the issue, it's time to start a new thread. Remember to:

Post the results of the wireless info script in CODE tags (http://ubuntuforums.org/misc.php?do=bbcode#code), or attach the .txt/.tar.gz file

Choose a clear and informative title:

"Heeelp, wireless doesn't work": No
"Atheros ABC123 drops connection, Ubuntu 14.04": Yes
