Wavemon is terminal user interface (TUI) that uses ncurses, which monitors wireless signal and noise levels, packet statistics, device configuration and network parameters. Use nmcli to show the available wireless networks SSID, mode, channel, transfer rate, signal strength, bars and security used using: This should already be installed on your Linux distribution, it doesn't require specifying the interface name, and can work without super user (sudo) privileges by default or at least that's the case in my test on both Fedora and Ubuntu. Nmcli, a command line tool for controlling and reporting the network status, can scan and list available WiFi networks regardless of the WiFi being connected to a network or not.

This can be useful to scan available WiFi networks to quickly see their signal strength, see their channels to know which WiFi channel to use for less interference, and so on. This article explains how to view available WiFi networks, list their channels, link quality, security, signal strength, and more on Linux using the command line.
