Your machine works best with a consistent, dedicated connection to the internet. This is because it must maintain constant communication to your server in order to check rates, balances, and conduct transactions.
Many modern bank ATMs often use fiber-optic connections for this. However, we'll just need to ensure a good connection. Please include connectivity as a factor when deciding a location for your machine.
Ethernet – A wired connection is far and away the best option. If at all possible, please use a hard-wired connection for your machine. The Douro is equipped with Ethernet connectivity built-in. The Trofa is Ethernet-ready, and uses a USB-to-Ethernet adapter.
3G/4G Hotspot – If Ethernet is not an option, a 3G/4G hotspot can deliver a fast, dedicated connection depending on your network's local signal. Signal strength at your location can be determined with a phone app (example). For more information on conducting a site survey or whether you could also benefit from an external antenna, consult this site.
Wi-Fi – A Wi-Fi signal may be sufficient when few, if any, other devices are also using the network. To avoid any instances of other network traffic being prioritized or interruptions in service, please consider a dedicated connection via DSL or Cable.
Changing Wi-Fi Networks
Trofa (7" Nexus) – Disconnect the machine from wall power. It will shut off within 5 seconds. Plug the machine's power back in. After rebooting, it will present the Wi-Fi selection screen.
Douro (10" Aaeon) – Because the Douro retains Wi-Fi connection info through power loss, the connection info for the machine will need to be removed. Please have a USB keyboard available and contact firstname.lastname@example.org for the tablet's password and instructions. (See: 'Changing the Wi-Fi network on the Douro')
Ports – The network must allow for traffic over port 3000 to communicate with your backend server, and over 8000 for our updater service.
No landing page – The network must not lead users to a landing page (such as a web-based login or for accepting terms and conditions.)
WPA / WPA2 – Wi-Fi networks must be secured to appear on the machine's Wi-Fi list.
