Massive packet loss over Ethernet backhaul
I believe I have read all the threads on this topic and tried the suggested solutions that are relevant to my particular network. My apologies if I have missed something!
My Orbi RBK50 (one rou...
Mooose Good troubleshooting and interesting observations. It's clear that the packet loss is directly related to the wired backhaul.
I'm now running the ongoing beta software (2.3.0.23) and I can see that NG has done quite good improvements on wired device handling. Would you want to test this SW and see if you will see improvements? If yes, please PM to ChristineT and ask to get the SW download links.
This is probably a silly question. There are four ethernet ports on both the RBR50 and RBS50. Did you plug the CAT6 ethernet cable into the same ports that were previously used for ethernet backhaul? Do you get the same packet drop when using other combinations of ports?
There is no packet loss for the laptop (10.0.0.33) wired directly to the router when the using 5G backhaul or no satellite, but with the Ethernet backhaul even this laptop loses packets. See ping results below for details.
Of course, FW V2.2.1.210, copy/paste error, sorry!
For the test below, the satellite was connected to Ethernet after the 5G test, i.e. it was up and running perfectly prior to connecting the cable.
All wired devices, including the satellite, have IP address reservations.
The firmware has been updated by clicking the update button in the web interface.
I have factory-reset both units previously in an attempt to solve a different problem, although I have not downloaded the firmware file from the support page and loaded it, nor have I tried factory-resetting this time around. Is this voodoo, or is there some technical explanation why this may work? I am reluctant to do this as I have IP address reservations and port-forwarding set up the way I need it, so I would really like to avoid this route if there is anything less time-consuming I could try first.
Not a silly question at all, switching ports has solved many issues for me in the past. Regrettably not this time though, and yes, I have tried.
So, here's the test I tried this evening. I started with 5G backhaul:
From the laptop (10.0.0.19) connected to the router through wifi with 5G backhaul:

From the laptop (10.0.0.36) Ethernet-wired to the satellite through a switch with 5G backhaul:
Ping statistics for 10.0.0.1:
Packets: Sent = 10000, Received = 10000, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 282ms, Average = 0ms
Ping statistics for 10.0.0.2:
Packets: Sent = 10000, Received = 10000, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 1ms, Average = 0ms

I then connected the Ethernet backhaul cable:

What happens if you disconnect the Orbi router from the ISP modem? Similar PL?
Can you try a different laptop or PC to compare results?
"From the laptop (10.0.0.19) connected to the router through wifi with Ethernet backhaul:"
When you mention this, is the laptop connnected to the Orbi router via wifi with it's ehthernet cable connected as well or disconnected? Or is this just the ethernet backhaul enabled and connected with the satellilte?
What is the mfr and model if this ISP modem. I believe it already has a built in router. Just curious is all.
Seen bad behavior after doing the auto update. Loads of users having problems using auto update. So reason for trying a file FW load and reset and setup from scratch. Helped resolve users issues in regards to auto update.
I would take a backup snapshot of the current routers configuration and save it to file. Then if you do the FW manual re-load and setup from scratch, run some tests first. Then apply the saved configuration to file.
I do not have a modem, the WAN port is connected directly to the fiber-optic to Ethernet media converter installed with the fiber-optic connection. My ISP supplies the external IP address on this interface through DHCP. There is nothing printed on the outside of the media converter enclosure except the MAC address, and I'd rather not break it open to find the model identification. I'm sure there is some way to poll it, but I do not know how. In any case, there is no router of any kind between the Orbi router and the fiber-optic connection.
I have not tried disconnecting the WAN. I will try this tomorrow, when others are not relying on the connection.
The wifi laptop (10.0.0.19) does not have an Ethernet cable connected to it, its only connection is the wifi connection to the Orbi router.
I have tried several other devices, including other computers, an Apple TV, a Nintendo Switch and the Raspberry Pi that runs Home Assistant. I haven't done any rigorous testing, but as far as I can tell the results are pretty much the same, i.e. packet loss with the Ethernet backhaul cable connected.
Thanks for the voodoo information. It may take a while to find time to try a manual update, factory-reset and retest, but I will do it when I get a chance.
