Thanks a lot for your answer. Let me answer your questions. Hope this helps.

 

Was this purchased new or used? If new, you could always contact Netgear and get a replacement.
It was purchased brand new from Amazon on July 31st. Maybe I'll contact Amazon or Netgear.

 

A few questions?
Of course.

 

Who is your ISP and what equipment did they provide?
It's SFR (France). They provide the Sagemcom f@st 3686 v1b cable modem. I put it in bridge mode to let the Orbi do the routing and DHCP part.

 

What is the current firmware on your Orbi device?
V2.5.2.20. Apparently, it's the last available firmware version.

 

What device is your Orbi router connected to?
It's connected to the cable modem on the WAN port and to a patch panel distributing the entire house (RJ45)

 

Is your Orbi router in router mode or AP mode?
It's in router mode (the AP mode is not available (greyed)).

 

Do you have any protection features enabled on the LBR20?
Not as far as I know. But I'll give it a check out this evening.
I refused Circle, disabled Armor, IPv6 is greyed. Concerning the other advices you give (Disabling Daisy Chaining, Fast Roaming, etc.), I'll check this evening. Those settings don't ring a bell right now ;)


Did you reboot your ISP modem/router, before starting the Orbi router install?
I'm not sure, I did a lot of reboots then :)

 

Have you changed the network cable connected from the ISP device to your Orbi router?
Yes, I changed the cable just to eliminate it as a responsible of the dysfunction.

 

Are your satellites wired or wireless?
I've one satellite, it's wired through the patch panel.

 

Thanks a lot for your help. I'll try to follow your advice and restart the configuration from scratch.

What patch panel are you referring to, what brand, and is the patch panel before or after the LBR20, or in between the LBR20 and satellite.

Which brings up another question, is your LBR20 directly connected to your ISP modem/router or is it connected to a switch or patch panel?

    What I called the patch panel is a kind of "switch" for home dispatching of TV (DVB-T or DVB-S), TEL or Internet through RJ45 outlets. I far as I remember (I'm not at home), there are 3 IN ports (TV, TEL and NET) and 8 OUT ports; for each out port, you choose what type of signal the outlet behind the port is expected to receive (TV, TEL or NEt). I suspect that those litlle selectors are only for visual purpose, it doesn't really filter the signal or wathever. Anyway, I only use that patch panel to connect the plugged devices to the LAN (no TV or TEL signals injected)
    Here is the model of that patch panel :

    Here is the chain of connection :

     

    • Cable Modem > LBR20 Router WAN Port (LAN 1) (Directly)
    • LBR20 (LAN 2) > Small netgear Switch (Netgear) (Port 1: NAS, Port 2: Hue Bridge, Port 3: Patch Panel) > Satellite and other wired devices (Macs, TV, STB, AppleTV, etc).

      Hi clemtys

       

      The expected failure switch time is 2.5 mins. 

       

      To verify, is this how you setup Failover: 

       

      1. Please make sure that you have the latest firmware v2.5.2.20. 
      2. Enable WAN/LAN port as WAN port only 
      Go to Advanced TAB > LAN Setup > uncheck "Enable WAN/LAN1 port as LAN port" > click APPLY to save the changes. 
      3. Enable failover mode
      Go to Advanced TAB > Setup > Internet Setup > Mobile Broadband Settings > Select "Use WAN Ethernet with mobile as back up in case of failure" 
      You will see the warning message "you have enable WAN/LAN1 PORT as LAN function when mobile mode, please disable it first". Click OK to continue. 
      4. Setup WAN 
      Go to Advanced TAB > Setup > Internet Setup > Internet Setup Page. Please input the WAN type and click Apply for setup 

       

      Regards,

        Hello Blanca_O ,

         

        Thank you for your detailed answer and sorry for my late feedback. I finally managed to find the time to check the settings as you suggested and everything seemed properly configured.

         

        You say that the expected switch time is 2.5 mins, which is good to know. Do you know if we can change this value and if not, do you know if it's planned to make it possible for a next firmware release?

         

        And, my last question is : do you know how the router detects a connection failure? Does it ping a specific IP (if so, which one?) for example ?
