RBR20 Connection Issues

I have had an ORBI RBR20 and two sattelites for about a year and a half. At first, it was connected to a DSL wifi router / modem, but in the spring we upgraded to cable. Since that time, it has been ...

IF your modem has a built in router, 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. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&app=desktop

Thanks! I thought of that and purchased a non-router modem, but the ISP won't let me use it. Apparently I have to use their modem. 

 

Couple of options,

Are these three options muturally exclusive? Should I start with one, if it doesnt work undo it and move to the next one? 


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.

It is my understanding that the modem is currently bridged and that the WIFI radios are turned off. Is "transparent bridge" different than "bridged mode"? 


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.

I am a bit confused by this suggestion... but am willing to give it a go. With the changes made above, I will wait to see what happens in a day or two. Is there a link for how to configure this way?


3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router.

I will research AP mode.

    Yes.

    It is my understanding that the modem is currently bridged and that the WIFI radios are turned off. Is "transparent bridge" different than "bridged mode"? Same.


    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.

    I am a bit confused by this suggestion... but am willing to give it a go. With the changes made above, I will wait to see what happens in a day or two. Is there a link for how to configure this way? This is only needed if your ISP Modem can't be bridged. 


    3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router.

    I will research AP mode. This is only if option 1 and 2 can't be configured on the ISP Modem.

    I can confirm that my orbi does not have AP mode turned on. 

     

    Side question: Can more than two sallelites be added to this system? I read on a retailer site "2 max." If I can add another one, any suggestions for a compatible unit? They dont seem to make the ones I already have.

      Some have reported 4 or more. I think the official is 4...

       

      However I would review placement and distance first before adding any additional RBS. 30 feet or more is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://https://https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

      Best deal going for new is the RBS40V for $99.00 US. Other than that, pretty much any AC satellite will work. There's always the used market as well.
