This script gathers the infos necessary for troubleshooting a wireless connection and saves them in a text file, wrapping it in an archive if it exceeds the 19.5 kB size limit for .txt attachments on the Ubuntu Forums.

• Creates the file wireless-info.txt at the location it is run from.
• Additionally creates the archive wireless-info.tar.gz if the file exceeds 19.5 kB in size.
• Masks all sensitive info, like MAC addresses and WPA/WEP keys, automatically in a meaningful way.
• Offers to post the results to your default pastebinit provider if the program is installed, and a sufficiently reliable internet connection is available.

You can either run it from the command line with these commands:

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

This will download the script, make it executable, and run it, all in a row.

Or, if zenity or kdialog is installed, run it from the GUI this way:

1. Download the script
2. Make it executable
3. Run it from your file browser or a Run dialog

If you cannot connect to the internet with the affected system, including via a wired connection, you will have to move files between it and a system connected to the internet.
