Need a way to list all the visible access points, with signal strength and signal quality, on a Ubuntu Linux system?
For a one-shot listing (with color coding):
nmcli d wifi
For ongoing listing:
watch nmcli d wifi
For something fancier:
sudo apt-get install linssid
Yeah, I know about WiFi scanners for Android and iPhone. In this case, I don’t actually need to know the WiFi signals – I need to know how well my Linux system’s WiFi card sees the signals.
