Orbi RBR850 V3.2.18.1 DHCP Assigning IPs every few seconds

Related question: Why is model RBR850 not in the selection list for this post?

 

I have an Orbi RBR850 with one satelite on firmware V3.2.18.1_1.4.14. I noticed that the logs were consitently filling up with DHCP assignments seconds apart and that the logs fill up daily. I have tried a few things like ensuring I have the latest firmware, ensuring my LAN settings are correct. and finally factory resetting and setting the whole thing back up again from scratch. Still I get assignemnts to the same device seconds apart and this happens across devices enough to fill up my logs daily. I have DHCP set up 192.168.1.10-254 and 1 static IP set outside that at 192.168.1.2. I have some port forwarding set up to that server but other than that the settings are pretty vanilla. I have attached a excerpt from today's logs with MAC addesses replaced with device names.

    It does not appear that anyone is assigned the task of keeping up the list of Netgear products. 

     

    Not only that, but someone decided it makes more sense to separate the community forum by product so that, for example, there is a sepatate forum for the "AX" product line, a separate forum for the Orbi "app" (which has almost no posts), a separate forum for the "Pro" line, for the "voice", for Orbi's with cable modems built-in, but not a separate forum for the outdoor satellite (RBS50Y).

     

    It seems that most people find the community forum by doing an internet search (I searched for "netgear orbi forum") and wind up here.

     

    Sometimes, a question clearly is more likely to get a response if posted in one of those other forums, so the response they get here is along the lines of, "nobody on this forum has one of those. Maybe somebody who does have one will have an answer." with a link to the forum:

    https://community.netgear.com/t5/Orbi-AX/bd-p/en-home-orbi-ax 

     

    Other times, the question seems to be generic and someone tries to respond.

     

    In regard to this DHCP question, does this happen to:

    • Only WiFi devices, or both wired and WiFi devices?
    • All devices, or only the ones specifically mentioned?

    I have only one Nest, and it renews the IP every 12 hours.

      I am seeing both wired and wirelss. The most common look to be the GalaxyNote8 (wireless) and the SonyTV (wired).

      I havent been checking the MAC addresses long enough to tell if all devices are being reassigned more often than 12 hours but I will keep an eye on it.

    These look quite similar:

    No answers there either.

     

    Along with the repeated DHCP lines my emailed logs also show an increasing number of entries like those shown in the links above.

    i.e.:

     Thursday, Jan 01,491926 -5:00:00
 Thursday, Jan 01,491926 -5:00:00
 Thursday, Jan 01,491926 -5:00:00

 Thursday, Jan 01,491926 -5:00:00

 Thursday, Jan 01,491926 -5:00:00

      Not a particularly helpful log message.  If the issue is worth devoting time and effort to, my approach would be to capture LAN packets and examing them with Wireshark. Routers do not spontaneously assign IP addresses.  Devices broadcast DHCP requests and routers respond to them.  The DHCP response contains the lease time.  If Orbi is assigning a very short lease, the device will ask to renew very soon.
