UPnP send/receive on RBR850 stops at MAXINT

I have already posted this but on the wrong forum (regular Orbi).

 

I use a software called PeakHour to monitor internet traffic from my Mac. It uses UPnP to obtain this information from the router. There appears to be a bug in the router where it stops reporting once it reaches MAXINT (4294967295 bytes). It appears to be very similar to this post here from 2019.

 

PeakHour provides a FAQ page to detect if the information over uPnP suffers from counter freeze. As can be seen in the attached screenshot, this seems to be a text book case: it reports exactly MAXINT for an unsigned 32 bits integer: 4294967295

 

This seems to be a bug in the router? If so, is this the formal way to log this bug, if not, where do I go?

Information about model/firmware:

Hardware Version RBR850
Firmware Version V4.6.3.16_2.0.51
GUI Language Version V3.0.1.2_2.1.30.3
Operation Mode Router

    I use PeakHour on a Mac to inform me about data traffic. After a while it drops to 0. It very much seems the same issue as has been reported before: https://community.netgear.com/t5/Nighthawk-WiFi-Routers/X6-R8000-UpNp-or-snmp-monitoring/m-p/1816959, but that's a post from 2019.

    P.S.: I could NOT find the model in the model drop down list box; I hope this is the correct forum. Information about model/firmware:

        > Is there a possibility that PeakHour is not actually connected to and monitorint the RBR850 at all?

         

        Thanks for your answer!I wasn't using SNMP but UPnP. If it weren't connected, it would never work, and the thing is it works for a few hours before starting to report zero. Using upnpc we can clearly see that both "Sent" and "Recv" report 4294967295 then, which is *exactly* 2^32 (unsigned maxint). So this does look like simply too small a data type to be able to track the bytes.
