Rbk50 system duplicate ips

I have a rbk50 with 2 ethernet backhauled satellites. About once a month a device cannot connect to the internet such as a firestick or phone. After doing an ip scan of the network and comparing to the assigned device list in orbi two devices are fighting for the same ip address. The only way to correct is the power off the router and satellites for a few minutes then power them all back on. Any ideas on why this is happening?

 

Thanks

    Is one of the devices listed in the LAN Setup table and the other not?

      Seem to be both wifi. I have ip reservations also but that range is not in the dhcp scope.

        Yes, the typical practice is to  set aside a range of IP addresses to use for certain devices (i.e. "reserve" or "assign" to these devices based on MAC address) and set the DHCP range of IP addresses so that there is no overlap.

         

        These two devices, then, are not in the LAN Setup table for assigned IP address, but are both somehow trying to use an IP address from the DHCP range, correct?

    What Firmware version is currently loaded?
    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
    Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

     

    Are the RBS Ethernet connected at the RBR or is there a LAN switch in between the RBR and RBS? If there is, brand and model please.
