Hi

 

Thanks for your advice. I will check today. I finished yesterday again in a situation where the router is non-accessible with the app or with the computer/browser and requires a factory reset. It is ON but here is no access to it.

Press the reset button in back for 15 seconds then release. Walk thru the setup wizard with a wired PC and web browser. 

 

I will reset it and check the firmware version. It refuses to find or install any newer firmware version, have tried several times. So that is not an easy cure.

The most recent code is not available thru the RBRs web page. You have manually download it and apply it:

https://community.netgear.com/t5/Orbi-AX/New-RBR750-RBS750-Series-Firmware-Version-v3-2-17-12-Released/m-p/2043556/highlight/true#M11417

Apply to the RBS first, then RBR lastly.

 

The modem is BGW320 from AT&T, I think it is Nokia but not 100 % sure. It works perfectly, no issues other than that its software is not the easiest to use, just disabling the wifi (it has wifi6) took a while...

Your ISP Modem already has a build 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

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

 

 

The distance to one satellite is 20+ feet and maybe 30 feet to the other one. There are ~ 2  light wooden walls in between. The two satellites are maybe 25 feet away from each other with almost visual sight between them. The old Orbi worked perfect in these same locations. I understand that the distance could be the problem, but should the router then collapse totally, and cannot be recovered without factory reset? Bringing the satellites back close to the router makes no difference after the collapse. Finding other locations for the satellites is not simple as we do have some equiment (surveillance etc) in those locations that have no wifi and require LAN connection to the satellites.

One way to test this out would be to turn OFF the RBS and run the RBR alone. However lets elliminate the modem causing problems. You may need more distance in between the RBR and RBS as well. 

 

When I bring the satellites to the right locations (from close to the router), they naturally find more wifi devices to connect, and at the same time get further away from the router. This is when the system stops working and does not recover. I will try today what happens if I do not do that, just keep them close to the router - we will see if the router stays functional a longer time.

 

I wll do those modifications you suggested and we will see, I hope they help. I will report later today.

Ok

 

I had a lot of problems with the old Orbis in the beginning as they stopped working quite often, and I almost threw them out, but software updates cured them all and I have been very happy with them since, they just work month after month. I hope to find a way to make these new devices work the same way, but I wonder if it should be this difficult, hi...

 

Thanks for you help, I appreciate it!
