Your machine works best with a consistent, dedicated connection to the internet over Ethernet. 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 on a location for your machine.
Ethernet via a router with a DSL or cable connection
A high-speed wired connection is far and away the best option. To avoid any instances of other network traffic being prioritized or interruptions in service, consider a dedicated connection via a cable or DSL service provider.
3G/4G hotspot over Ethernet
If a cable or DSL connection 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. Use a hotspot which provides an Ethernet port to connect to the machine, rather than Wi-Fi.
We do not recommend Wi-Fi. The greatest reliability is obtained from connections over Ethernet and operators who have upgraded their wireless connections to wired ones found significant improvements in stability and uptime. A Wi-Fi signal may be sufficient when using a dedicated connection and without nearby networks using similar wireless channels, though not when shared among other network users.
Changing Wi-Fi Networks
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 our support for the tablet's password and instructions. (See: 'Changing the Wi-Fi network on the Douro')
Sintra, Sintra Forte, Gaia, Douro II – Our latest models provide connectivity over Ethernet only for maximum stability. To connect to a Wi-Fi network, you may use a travel router that itself connects to Wi-Fi and outputs to Ethernet for the machine, such as the TP-Link AC750.
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.
