Satellite disconnecting

For starters I would do a search here on V2.5.0.38 

Lots of complaints  

How did you get the firmware version?

Modem Combo Units:
This would be a double NAT 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

What is the size of your home? Sq Ft?
What is the distance between the router and satellite(s)? 30 feet is recommended in between RBR and RBS to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/000036466/How-far-should-I-place-my-Orbi-satellite-from-my-Orbi-router

What channels are you using? Auto? Try setting manual channel 1, 6 or 11 on 2.4Ghz and any unused channel on 5Ghz.
Any Wifi Neighbors near by? If so, how many?

Try enabling Beamforming and MIMO(MIMO may or maynot be needed) and WMM. Under Advanced Tab/Advanced Settings/Wireless Settings

Try disabling the following and see:
Armor, Circle, Daisy Chain, Fast Roaming, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Save settings and reboot the router and satellite(s).

Has a factory reset and setup from scratch been performed since last FW update? I and others are having good operation on v38:https://community.netgear.com/t5/Orbi/ORBI-RBK50-RBS50-Tips-Tricks-Hidden-Secrets-etc/m-p/1818889/highlight/true#M74523

Solid operation...

Only one known confirmed issue with device naming which NG is aware of.

Hello Orbi experts

I have an almost new Orbi RBR50 and satellite set up at home.

 

Problem: My Orbi satellite drops connection to the Orbi router intermittently. This has only recently started (there hasn't been any new wifi connected items since installing Orbi).

 

Observations: Without apparent cause, the satellite leds start to flash white quite fast, then flash white slower, then solid purple and then off as the satellite reconnects back to the router. This causes my iOS devices to lose internet connection until the satellite has reconnected, which can take around 5 mins. This occurs at random times of the day and night with little or no external influence on the satellite (i.e. multiple movie streaming etc).

Something that might be an associated isssue is that, for example, if I attempt to stream a movie on my iPad Pro, (which is located approx. 8m from the router and 8m from the satellite), the iPad tells me that I have a wifi signal, (mostly with two wifi bars but somethimes with three), but the Orbi app tells me that there is no internet and ends up either crashing or spinning until I close the app). The wifi signal strength evident on the iPad varies significantly and is often thr cause for the internet connection to be droped entirely, the connection is then lost. Even if the iPad Pro is positioned next to the satellite, it rarely shows more than two bars of wifi strength.

It might be coincidental but I have noticed that if I switch off the satellite, I get a more stable connection, even though the wifi signal strength is diminished further.

 

Solutions tried: I have tried moving the satellite closer to the router. When it was working and stable, it was located about 10m (direct distance) from the router. I have tried moving it to a location 8m direct distance from the router, but this has not helped. Last night at around 2:30am with the satelite located near to my iPad, the satellite disconnected and then reconnected - no one was using the internet at that time.

I have also tried rebooting the router and after reading a few threads switched 'Daisy-Chain Topology' off. This hasn't made any difference.

I have tried setting the 2.4GHz chanel to 1 (aas per other threads) but this has made no difference.

 

Set up and other things: The router is connected to my TP-Link ADSL modem/ router (TD-8980) via ethernet. The ADSL modem is connected to the main incoming telephone mastersocket and has wifi mode switched off. The Orbi router has the most current firmware V2.5.0.38 installed. I think the router is set up in Router mode. The ORBI portal is showing the Internet as Good and the satellite 'backhaul status' as good (at the moment). The router maintains connection to the internet and has not yet started to randomly disconnect. I do not have more than two other neighbourhood wifi networks in my vicinity (I notice a BT Hub and TalkTalk network mostly, but these have never caused any issues before Orbi arrived). I have a total of 10 devices connected, three are ethernet wired into the router, the others are via wifi. These seem to be working ok.

I have the 2.4GHz chanel set to 'Auto', and the 5Ghz is set to 'Ch36'. I am using WPA2-PSK [AES] security settings. IPv6 is disabled.

I live in a fairly modern, medium sized four bed house that has internal walls made of drylining and timber stud.

 

Help and solutions?: What can I do to get a more stable wifi mesh network as at the moment, as I don't think the Orbi system has improved wifi across the house.

Many thanks

Chris

This new firmware v2.5.0.38 is atrocious,

I was having the same issues and worse. Anyway after a factory reset and no improvement in connection I downgraded directly to the last firmware v2.3.5.30 (first the satellite then the router.) 

Anyway here's a direct link to the last good Firmware from July, you can downgrade to it directly https://kb.netgear.com/000061080/RBR50-RBS50-Firmware-Version-2-3-5-30 

I found it by just going to the Orbi Download page and clicking view previous verions. I was able to downgrade directly to v2.3.5.30without doing some two step downgrade like it says to do to go from v2.2.1.212 to v2.3.0.32
