    The Draytek Vigor2765ac looks like a DSL modem router.

     

    Not sure what you mean by "fiber glass connection". DSL usually gets to customers over a copper cable. (Every Internet services has optical links somewhere on the network.) If you really do have an optical fibre for your Internet, then you should be able so use that with the Orbi router without a modem.

    For the RBR850, there is no "bridge mode". That is something that you should do with the Draytek device. Maybe that what you mean.

    I'm not sure what that means. What is the KPN site?

     

    There are sites that explain how to put the Draytek into bridge mode. Start with the Draytek manual.

     

    Vigor2765 Series | DrayTek

     

    If that is not possible, then put the Orbi router into access point (AP) mode.

     

     

    Just another user with time on their hands.

      Hi Michael,

      Thanks. for your comments.

       

      Kpn in in the Netherlands is the provider and all providers supply there own modem.

      That is how it is arrange in The Netherlands no other option on that.

      on this Draytek the have a special socket for glassfiber entery .

       

      So in The Netherlands i can't use the Orbi as a modem / without the draytek.

        Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT
        https://kb.netgear.com/30187/How-to-fix-issues-with-Double-NAT
        Couple of options,
        1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
        2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
        3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router.
