If you have ever used the popular software InSSIDer on Windows or OS/X, you might wonder if there is an equivalent application for Ubuntu/Linux.
LinSSID allows you to visually survey the Wifi networks in your area, identifying networks using the same channel as your own, even if they are not broadcasting SSID’s.
sudo add-apt-repository ppa:wseverin/ppa
sudo apt-get update
sudo apt-get install linssid
— OR —
sudo vi /etc/apt/sources.list
deb http://ppa.launchpad.net/wseverin/ppa/ubuntu YOUR_UBUNTU_VERSION_HERE main
NOTE: it seems that the release version is only available for ‘precise’ and has not been updated for newer Ubuntu releases, I was able to simply go to the terminal and execute "
software-properties-gtk" to change ‘trusty’ to ‘precise’ on the PPA and it worked great!
