#RaspberryPi – Update or setup Wifi configuration in Ubuntu

Hi !

This is not a Raspberry Pi specific post, however I always forget how to this in Ubuntu, and I’m so used to raspi-config in Raspberry OS, that I may write this down.

Ok, so let’s setup the Wifi in Ubuntu. 1st let’s change the 50-cloud-init.yaml file.

 sudo nano /etc/netplan/50-cloud-init.yaml

Let’s edit the file and add the Wifi information.

 network:
     version: 2
     wifis:
         wlan0:
             dhcp4: true
             dhcp6: true
             optional: true
             access-points:
                 "<Wifi name>":
                     password: "<Wifi password>"

Important: use spaces, not tabs. That’s it!

Close, save and reboot !
