RBS850 ethernet backhaul connected to switch results in loop warning light on switch

Question

I've been having internet connection issues for some time now. I've done a lot of troubleshooting for various things over the last couple months or so after updating firmware. I have now discovered that the loop warning light on one of my switches is on. I thought maybe it might have been elsewhere but I'm the only one that configures the network. Sure enough it goes out as soon as I disconnect the ethernet cable to the satellite.

I'm thinking at minimum powering the satellite on and off to see if that fixes it. Maybe a reset? I see that there has since been another firmware update so I'll save that for last.

Any ideas why this would happen? I know there used to be a "wired backhaul" check box for my 700 series Orbi. I assume it's gone now because it switches automatically with the 800 series. Does it reset itself with a power cycle?

What Firmware version is currently loaded?What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.&nbsp;

What is the Mfr and model# of the ethernet switch in the configuration?
&nbsp;
How was the RBS connected to the RBR? Wireless sync first then after that, they should connect ok one at a time via ethernet.
What CAT# cable is being used in between the RBR, switch and RBS?&nbsp;

You really didn't give us much info other than you have an 8 series orbi and a switch.&nbsp;
What switch is it?&nbsp;
How do you have everything wired?&nbsp;
It should go modem/gateway into the RBR850's wan port. Then from the RBR850's lan port to switch/satellites.&nbsp;

So you're going S33----&gt;rbr850 wan port-----&gt;switch------&gt;satellites?&nbsp;
&nbsp;
One thing to try is power off the satellites for a short period of time after the router/switch boots and then boot them up.&nbsp;
I've seen it with mine where it'll establish a wireless backhaul first and then the wired. Maybe if they boot up after the router/switch, the wired backhaul will default to that.&nbsp;

Yes. I only started having connection issues after the V4.6.9.11 update. I assumed it was understood that everything was connected properly, I apologize if that wasn't clear.&nbsp;I have powered down everything countless times since updating. But I'm not sure at what point this loop light was on.&nbsp;&nbsp;I'm guessing this issue is what's causing my log in credentials at work to be locked after using the VPN for work.&nbsp;&nbsp;I will try to power down again, waiting a few moments before powering up the satellites.&nbsp;Another interesting thing is that the particular satellite that is having the issue is stuck in "please wait a moment" when looking at firmware update page. Which doesn't allow me to update the other satellite or router. I'll eventually try the manual route I guess.&nbsp;
