Some networks (ie UNI etc..) will need to whitelist a devices MAC address before it can connect. The easiest way to find this is by putting the departure board into its WiFi setup mode then connecting to it via a phone or laptop and then clicking on the ‘DepartureBoard’ network settings and viewing its MAC address. You can also do this via windows and check the MAC address via the `arp -a` command via windows shell/command prompt.
