Changing the Wi-Fi network on the Douro

Once connected to one Wi-Fi network, the Douro can be changed to another with the following process.

Note: In all cases Ethernet is highly preferred to Wi-Fi. The machine needs a highly reliable connection to your server for consistent, periodic requests, and Ethernet (and a dedicated connection) is the best means to ensure this. (See: Best Practices for Connectivity)

Logging in

Connect a keyboard to one of the USB ports on the top of the tablet computer located inside the door.

Press Ctrl+Alt+T to bring up a terminal window.

Run:

sudo su

Then enter the root password (provided separately).

To clear the current Wi-Fi network

Run:

clear-wifi

If the above returns 'Command not found', instead, run this command:

echo -e "network={\r\n}" > /etc/wpa_supplicant.conf

Then, run:

restart lamassu-machine

You should then see the machine go to the 'Select Wi-Fi network' screen. You may close the terminal and remove the keyboard.
