How to install LinSSID on Ubuntu 12.04

I needed to do a network survey the other day to see if wifi was working as expected and I decided to use my Ubuntu laptop for the purpose, I ran into this handy tool called LinSSID that allows you to do a wireless survey. The reason I am using Ubuntu 12.04 is that I feel that the LTS releases are the most stable and have the broadest install base so that is what I tend to use on my computers.

  1. Install LinSSID from it’s download page.
  2. After it is installed I found that I got an error stating that it could not see any wireless devices so I installed IW by typing the following command into the terminal[shell]sudo apt-get install iw[/shell]
  3. I was then able to run LinSSID by typing[shell]sudo linssid[/shell]

    in the terminal.

  4. (optional) If you would like to try combining steps 2.1 &3 try[shell] sudo apt-get install iw && sudo linssid[/shell]

Let me know in the comments if it works!
