47% packet loss

I've installed the replacement unit in AP mode as well and there was no package loss. Then I changed it to Router mode & bridged my modem today. Packet loss on 192.168.1.1 is back.

 

Is this normal, anyone else is experiencing the same thing?

Attached is a Ping Plot I just did to Google.com.  Zero packet loss to any node that responds to ICMP (notice that  node 2 does not).

The Orbi has been replaced, but the problem remains and shows up only in router mode.  I wonder:

• The Orbi router will still have an IP address, even when in Access Point mode.
  Can you run Ping Plotter against that IP address by itself?
• It appears to me that the only "constant" in the problem is the Mac that is running Ping Plotter.
  Can you get access to some other computer? (invite someone over with a laptop - and a mask, of course)
  Would be useful to see if other devices report the same results.

If packets are actually being "dropped", I would expect the reports for every node after the Orbi to also report packet loss.  Perhaps my understanding of how "ping plotters" function is incorrect.  PingPlotter provides a really slick description of the product here:

But, they never say how those intermediate "hops" are discovered and measured.

My understanding is that the program does a "Trace Route" to determine how many hops there are and the IP address of each hop.

It then looks up the DNS names of those IP addresses to create a more "user friendly" display.

Then, it sends a series of ICMP requests to every hop in the router.  i.e. to hop 1, to hop 2, to hop 3, etc.and records how long it takes for each response to return.

Something is going wrong with ICMP to hop 1, but not to any other hop.  If the Orbi is "dropping packets", then it should drop packets that are going everywhere, not just drop packets intended for the Orbi router.

Sorry to go on (and on). I have a feeling the problem may be with the measuring process, not with the network.
