RBR850 won't talk to modem

Brand new ORBI 6 router creates a great network with two satellites. Multiple devices connected to router and satellites. Alas - no internet. The RBR850 router will not communicate with my Genexis Hybrid modem, connected via the same Cat 5e cable through the same physical ports as my old RBR50 which still works fine when I plug it back in. 

 

Is there any reason why WiFi 6 should require different settings on my Genexis (which I believe to be non-user-configurable)?

 

Or is the solution in the ORBI settings somewhere - I haven't fiddled with them yet.

    No reason.

     

    Ensure your CAT5E cable between the modem and the router is a fully fledged one with eight strands/four pairs so the GbE negotiation can work. Temporary workaround to overcome the very rare GbE auto negotiation issues is to loop in a simple non-managed Gigabit Ethernet switch.

      Thanks I have changed the cable to one I know to be of high quality. No difference. I have now put the ORBI network into AP mode and it has accessed the internet and is communicating with satellites. I also seem to have a guest n/w which I had thought was not possible in AP mode. So for the moment I'm happy with it...

  • What Firmware version is currently loaded?
    What is the model# of the Internet Service Providers modem/ONT the NG router is connected too?

     

    Has a power OFF of the ISP Modem or ONT and RBR for 1 miniute then back on resulted in anything?

      new firmware loaded - v.25 I think - once I'd configured the router in AP mode and could get online. The ISP modem/router doesn't have a model no... it's just a Genexis Titanium built on their Hybrid platform. And no, multiple restarts and reboots - with everything in the house turned off or disconnected - have had no effect.

        Does the ISP modem.ONT have a built in router or just a modem/ONT only? 

         

        You night have the ISP check the configuration of there modem/ONT and see if there is anything they can help with. AP mode should work. 

        Is the RBRs web page reporting Internet status on the home base page?

         

        Did you configure the RBR for Dynamic or Static IP addressing for AP mode? 

         

        You are connected to the ISP modem/ONT using the WAN port on the back of the RBR? 

        v6 is the lastest version:
