Hi all,I regularly observe ethernet disconnection of the RBE971 (firwmware V9.12.2.1_1.2.10)Setup is set as follow:RBE971 in AP Mode connected throught ethernet to a Linux router, ethernet card is an Intel I-226V (2.5g).I've tried all the ethernet interfaces of the RBE971, and i face the same issue.On the router side, the RBE971 is part of a linux bridge, where spanning tree is disabled.But i observe the same issue when the RBE971 is not part of the linux bridge. Does anyone observe similar issues? Also, from time to time, i can observe random reboot. I've open a case for this one, but did not get much traction, yet.Thanks

As i said previously, the RBE971 is configured in AP mode.IP address is obtain by dhcp from the router.Setting a static IP will do nothing here, since the link is physically down when the problem occur.

(another random thought...) You may have seen the discussion regarding the 971 product overheating and using a fan above the case to pull air through the case rather than rely on convection cooling. Establishing that the temperature is not too high would be another piece of information.

Trying the RBR in router mode would be a good troubleshooting step to see if this issue is still being seen in this mode as a temporary quick test. If it is, maybe some problem with the RBR system. If not, then maybe a problem coming from the upstream host router. Just had my 970 series in AP mode for past 11 plus days of up time, so I know this works: Mine was connected to NG XR series router and it connected to a CM3000 cable modem.

then the upstream router will definitely not be the problem. the number of times of heard "its definitely not my gear" and then it is, isn't a small amount. In AP mode, that upstream router is controlling quite a few things that could cause issues. Which features are disabled on my Orbi router when it is set to AP Mode - NETGEAR Support

are you going: Linux router----->wan port on 971--->lan port out----->971 satellites? What linux router is it? What gateway is the linux connected to?

What linux router is it?

  Hi Plemans,
  
  The linux router is connected with fiber to my ISP, meaning that i maintain my own router here, which have always worked.
  
  ISP ---> Linux Router ----> Wan port on 971 -----> Wifi BlackHaul ----> 970 Satellite
  
  I tried the 10g wan port, the 10g ethernet port, and all 2.5g ethernet port on the 971 with same results.

    have you tried going ISP gateway--->Orbi?
    Pull out the linux gateway to see if its causing an issue.

What is the indication of Ethernet disconnection?

LED on the server Ethernet RJ45 connector indicates loss of connection?
(a bit frustrating that Netgear did not provide LEDs on the router RJ45 ports, but understandable that many customers would not want "blinking lights" if the router is placed where they would be a distraction.)

The Linux server alerts that "connection lost"?

The Orbi router Advanced Tab display "Show Statistics" indicates no connection?

Devices connected to the Orbi router lose internet?

Does anything appear in the Orbi log?

How is the RBR configured or AP mode? Using static or dynamic IP address configuration?

How I have my 970 series configured for AP Mode using wireless BH connections for the RBS:

Does anyone observe similar issues?

    Does the RBR and RBS work if you configure router mode on the RBR and use the host routers DMZ for the RBRs IP address it gets from the host router?
    
    What CAT# LAN cable is being used? CAT6A STP is recommended.
