Nanoleaf Router Settings for optimal LIGHTLINK connection.

Yes. LIGHTLINK uses something called 'UPnP' (Universal Plug-n-Play) to find the IP address of your Nanoleaf. Many routers have a security setting that allows you to turn off UPnP. Some people do this for security reasons, to prevent their home automation devices from being discovered by unauthorized people. If this is preventing LIGHTLINK from connecting to your Nanoleaf, you only have to turn UPnP on (in your router settings) while LIGHTLINK is connecting to your Nanoleaf for the first time. Once you have connected the first time, you can turn UPnP off again, if you would like, and LIGHTLINK will remember the connection information to play light shows each time you open the app in the future.
