Orbi RBR20 static route issue

The title on this post is incorrect.  Static Route refers to a router setting to direct connections to a specific IP range to a specific port. This is often used when the router is connected to a company network using a different internet connection.  Using the LAN Setup to reserve specific IP addresses within the IP subnet for devices is called device reservation.

The first thing to check is that the device continues to present the same MAC address when it attempts to connect.  Apple, Android, and many laptops now include a feature whereby devices present different MAC addresses under some circumstances.  It is important to set the device not to do this when connecting to the home WiFi system.
