Apparently Orbi makes very little effort to maintain lease history and/or attempt to reissue the same addresses. Since employing Nagios a week ago I've watched two devices change IP addresses without explanation. This should not be happening since we aren't even remotely close to the number of addresses allocated.
Note: If you are running TiVo, you will need to create reservations for all source (i.e. DVR) devices on your network. If a source device changes addresses it screws up the TiVo beacon process (Bonjour/zeroconf) and you will need to repeat guided setup on all remote (i.e. mini) devices.
