Ethernet Backhaul
I originally set up the system with wireless backhaul. Just now reconfigured as wired. Router status still shows satellites connected as 5G. Do I need to reset the satellites or perform some other...
Hi,
if you get the chance to login into your router via telnet, you could check the STP parameters of your network, because STP should prevent such events… Also, do you happen to have anothet router in your system?
Hi,
Just a regular telnet session to my router's IP doesn't work. Is there anything special I need to do to telnet into it? Also, how do I check the STP?
I have another router on my network but its DHCP server as well as Wifi is disabled and it is being used as an access point, to connect one room with multiple devices (via its gigabit ports).
I can try taking this off the network but it's not a solution for me, as I need this device for my file server etc to talk to the rest of the network.
You will have to enable telnet for your Orbi on the debug page: http://<your orbi>/debug.htm
If you really do have another router on your network, or a switch for that matter that does support Spanning Tree (STP), then you should make sure, that the "central" one, has the STP bridge with the lowest number/ID, which will make it the root bridge of you rentire network.
However, it might be easier to disconnect the other router for testing. Just for the sake of completeness, this is what my router (in AP mode) tells me about its STP config:

You can see, that each wireless interface has a path cost of 100 assigned to its designated root bridge, which happens to be the one br0. There musn't be any other bridge designated to these interfaces, that would indicate that there's another root bridge on your network somewhere, which would at least be an performance issue, since all traffc would be routed via that remote bridge.
Also note, that eth1, which is my ethernet backhaul only has a path cost of 4 assigned to it, make it the way of choise for all MACs that are "seen" on that interface.
Thank you!
I telnetted into my router and I am going to paste what it says here.
Also, something definitely weird is happening here. I reattached the cable to a different port on the router and it showed the satellite come up as a wired connection. So I quickly tried copying over a file on my network and it copied over around 100 MB/s (or around 800mbps). I usually never get these speeds on the wireless backhaul (usually get around 30MB/s) so I knew the wired one is working.
Then after 30 seconds, the satellite showed as Disconnected on the Attached Devices page. The Wired connection was still working and fast but it stopped providing Wifi (and specifically Internet) to any devices connected to the Satellite. After another 30 seconds, the Satellite displayed as a Wired connection and everything came back to normal (still fast Wired ethernet and Wifi to all devices). Another 30 seconds and it showed as Disconnected and the same thing happened.
This kept happening till it started staying more on the Disconnected side of things than connected. And my wife shouted as she was trying to work so I have stopped testing for a while ;)
Let me paste the telnet data from my router. This is from when it is connected on a 5G backhaul as it is not stable enough for me to reliably connect to when I attach the wire.

Any help or anything you can make out from here would be greatly appreciated!!
Are you running your router in actual router or ap mode? I can't say for sure, if the router is in routing mode, but the path costs are all 0, which cannot be correct - at least the path costs for the wireless interfaces should be way higher than the wired ones.
You maybe want to check the bridge on your satellite as well and reset it to factory defaults, if there are also such weird values.
