Simple wifi with iwd and networkd for Arch Linux

Original source.

Install and Configure iwd

1. Install iwd

        $ sudo pacman -S iwd

2. Configure iwd by editing /etc/iwd/main.conf

        [General]
        # uncomment for setting the wifi interface name yourself
        # see https://iwd.wiki.kernel.org/interface_lifecycle
        #UseDefaultInterface=true
   
        # enable builtin DHCP-client within iwd for wifi
        EnableNetworkConfiguration=true
   
        # randomizes mac-address every time iwd starts or the hardware is initially detected
        AddressRandomization=once

3. Enable iwd.service

        $ sudo systemctl enable --now iwd.service

   wireless networking with DHCP is now up and running.

Connect to simple PSK wifi networks in the iwctl shell:

1. To get an interactive prompt do:

        $ iwctl

2. If you do not know your wireless device name, list all Wi-Fi devices:

        [iwd]# device list

3. To connect to a network:

       [iwctl] station <devicename> get-networks
       …
       [iwctl] station <devicename> connect <network-name>

4. Alternatively, you can supply it as a command line argument:

        $ iwctl --passphrase passphrase station device connect SSID

Configure systemd-resolved for DNS

1. Enable systemd-resolved.service

        $ sudo systemctl enable --now systemd-resolved.service

2. Make /etc/resolv.conf as a symlink to /run/systemd/resolve/stub-resolv.conf

        $ sudo ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

3. Restart systemd-resolved.service

        $ sudo systemctl restart systemd-resolved.service
