Orbi Ethernet Backhaul causing broadcast storm

I have just upgraded my Orbi router and satellites to V2.1.1.12 hoping to take advantage of the recent Ethernet backhaul feature.  I use the Orbi router as my main router with a 24 port switch servic...

As theorized, wireless and wired backhaul create a loop and flood the network with broadcast traffic. It's interesting that stp is disabled by default on the orbi router when this is the exact scenario where stp is needed. packetwerks is right when they say that this is something Netgear needs to fix. Any adjustments made on a switch (managed or not) are simply stop gaps. Hopefully the people who can fix it actually pay attention to the forums.

    Yes I've sent this in for review and tagged some mod's on this. 

     

    Ya so for now, try the work around on your managed switch or put a non managed switch in place. Hopefully NG will figure this one out. Been a bug for a while now.

      I can confirm the latest firmware, 2.1.4.16, enables spanning-tree (stp) on the Orbi router. This prevents loops, and therefore broadcast storms, from occuring. Wired backhaul is now stable for me, managed switch and all, even through multiple reboots.

       

      Now if only Netgear could make it so the magenta LED doesn't glow in AP mode (since you're using the LAN port)...

       

      Perhaps I'll keep my RBK23 afterall. Thanks FURRYe38.

        I'm using the WAN port in AP mode and it works great and no magenta LED, but no wired backhaul here.  Why can't you use the WAN port?  Is it because of wired backhaul? Did you try the WAN port with the 2.1.4.16 firmware?
