Fedora wireless analyzer

edit

It's not graphical, but it's quite easy to use: just run iwconfig to find out what adapters you have, and once you see the one for wifi (for me it was wlp7s0), run the following command (replace wlp7s0 with the name of your adapter):

sudo iwlist wlp7s0 scan

If that provides too much information for you, you can run that output trough grep like so:

sudo iwlist wlp7s0 scan |grep -e Signal -e SSID

That command only displays the signal strength of a network together with it's name, you'll be able to search for other things too with grep.

iwlist substitute wireless interface designation here scan

example: iwlist wlp3s0 scan
