Part of the Arch Linux appeal is how minimal it is, so minimal that you have to manually connect to WiFi with iwctl. The iNet Wireless Daemon comes a set of command-line tools for interacting with your wireless network card, and wireless routers. Using these tools, we’ll be able to connect to a wireless network with only a few easy steps.
While this isn’t necessarily something you’d need to do if you install a desktop environment like GNOME or KDE, but it definitely comes into play during the installation of Arch Linux, which is as pared down as it gets.
Since I don’t setup Arch very often, maybe once a year or so less, I tend to
forget how to connect to the Internet during the initial setup. Previously this
was done with
netctl by way of the
wifi-menu command. It used to be a very straight forward process. Simply execute the
wifi-menu command and run through the prompts, answering things along the way.
wifi-menu doesn’t seem to be bundled as part of the base Arch Linux image any longer.
Launch the prompt
What is included is the iNet wireless daemon (
iwd) which gives us the
command. Upon running
iwctl you are dropped into the

[iwd]# prompt you will need figure out your device name. Then, assuming you know the SSID (service set identifier) of your wireless network, go ahead and connect like so:
For a secured wireless network, you will be prompted for the WiFi password. Once you enter the correct password, you’ll be off to the races!
Of course, if you don’t know the SSID for the network you’re connecting to, you
can scan for available networks:
Disconnect from WiFi
Once you’re done with needing Internet access, you can tell
iwd that you’d like to disconnect. Armed with the device name of your wireless network card, simply run:
