How one can Connect with Wi-Fi By way of the Linux Terminal With Nmcli

Would you like to connect to a Wi-Fi network using the Linux command line? Here's what you need to know about the nmcli command.

Need to connect to the Internet on your Linux device but don't have an Ethernet port or access to graphical network software? This article will show you how to use the nmcli command line tool to connect to Wi-Fi in the Linux terminal.

What is nmcli

Nmcli is the command line interface for NetworkManager, a popular Linux application used to identify and configure Internet connections. Many distributions have a graphical applet for using NetworkManager in a desktop environment. However, if you are on a Linux server, you may not have access to a desktop.

Some methods of connecting to Wi-Fi through the terminal are a little tricky. This includes configuration files and knowing your PSK key.

Not so with nmcli. Assuming you have a modern router, all you need to know is that of your network SSID (the name of the network you want to connect to) and the network password, if any.
