RBK850 - refused to connect

Hi All,

 

My previously fully functioning RBK850 with the latest firmware does not allow me to connect on his IP address, neither the app can connect. It is simply telling to me "Refused to connect". I tried to power cycle the device with not much luck. I really want to avoid any factory reset - is there any other option? (I have 1 satellite connected)

    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? 

     

    If you can not get to the web page of the RBR850 at all or orbi app fails to connect, you'll need to factory reset the RBR and setup from scratch. Press the reset button in back for 15 seconds then release. Give about 2 minutes and walk thru the setup wizard with a wired PC and web browser:

      I'm really unhappy restore a working device, but anyway... Questions:

      • Is there any risk, that I cannot reach the web page after reset, too, making the device unusable?
      • I have 1 main device and 1 satellite - in which order should I reset them?
      • After factory reset, is it OK to restore the last known working backup, or better to setup everything manually?

        Perhaps it would be useful to review some assumptions:

         

        The default behavior of Orbi routers is to create a LAN subnet of 192.168.1.x, with 192.168.1.1 being assigned to the router itself and other devices getting IP addresses from 192.168.1.2 through 192.168.1.254 (or whatever DHCP range the router has been configured for).

         

        Q: is 192.168.1.1 the IP address that the web page is attempting to open?  Have you tried using a URL rather than an IP address, such as http://orbilogin.net?

         

        There are a number of situations which cause the Orbi router to change the LAN subnet, often to 10.0.0.x, with 10.0.0.1 being taken by the router itself.
        The way to determine if this has happened is to look in the network setting to find the IP address of the gateway.

         

        p.s. Yes, Netgear product numbers can be confusing.  For several years, Netgear followed a pattern with Orbi systems.

        RBK850 indicates a "Kit" consisting of one RBR850 (R for 'Router') and one RBS850 (S for 'Satellite')

        RBK852 indicates a Kit with one router and two satellites.

    Thanks for clarifying the IP address.  Can you "clear the cache" on the web browser and perhaps try another browser?

    Yes, and "watch out".  If a Factory Reset is done while the router is connected to the modem, it will almost certainly detect the IP conflict and switch to 10.0.0.1.

    (This would not happen if the router is not connected to the modem when reset.)

    Loading the saved configuration should return everything to the way it was (192.168.0.x, etc.)

     

    So, I would unplug the modem, do the reset, load the saved configuration, then reconnect the modem.
