Maybe not relative here or not but FYI, you might also want to look into changing the IEEE address of your Zigbee Router adapter to make sure it uses a unique IEEE address.
The scenario when you absolutely would need to do so is if you have first used the “old” adapter as a Zigbee Coordinator and then migrated from it to a “new” Zigbee adapter before re-purposing the “old” adapter as a Zigbee Router in the same Zigbee network.
The reason for that is that when migrating an existing Zigbee network from a other Zigbee Coordinator then part of that process has been to copy the IEEE-address from the old adapter to the new, thus you have two adapters with the same IEEE-address. This will cause problems if you then add the original adapter back to the same Zigbee network before manually changing its IEEE-address as it should never have two devices with identical IEEE-addresses.
If you do manage to get two different devices with exactly the same IEEE-address on the same Zigbee network then routing will get screwed up. so at least it will not hurt to change the IEEE address of Zigbee Router devices as what that is in the Zigbee network is unique MAC-address for addressing that specific device.
You can find links and information about how to change the IEEE-address on CC2652 based adpaters here:
Note! If the Zigbee Coordinator shows its ieeeAddress as 0x000000000000000 then it is screwed up (needing to write a new IEEE address to Zigbee Coordinator, reform whole network, then re-pair devices).
