Next, enable the service to start up on boot:
<source lang=bash>
systemctl enable wpa_supplicant@wlan0

Create the file /etc/systemd/network/wlan0.network with:

</source>
 
Enable networkd to run dhcp on startup:
<source lang=bash>
systemctl enable systemd-networkd
</source>


See the [[#Debian_Networking|systemctl-networkd]] example for setting a static IP for a network interface.  The wlan0.network can be configured the same way as an eth.network.  To enable all of the changes that have been made, run the following commands:
<source lang=bash>
<source lang=bash>
systemctl enable wpa_supplicant@wlan0
sudo chmod 600 /etc/netplan/*.yaml
systemctl start wpa_supplicant@wlan0
sudo netplan apply
systemctl restart systemd-networkd
</source>

Wireless configuration under Ubuntu, similar to Ethernet, also uses netplan for configuration. For example, create /etc/netplan/wifi.yaml: 

network:
  version: 2
  renderer: networkd
  wifis:
    wlan0:
      dhcp4: yes
      dhcp6: yes
      access-points:
        "yourssid":
          password: yourpassphrase"

After creating the yaml file, set the appropriate permissions and apply the netplan: 

sudo chmod 600 /etc/netplan/*.yaml
sudo netplan apply
