Hello. I have a 200MB fiber in my home. I have a 200 square meters apartment. Few wifi access points near by and I have already checked which channel they are using.I have purcheased an Orbi Mesh WiFi 6 RBK753 with 1 access point and 2 extenders. Sadly for unknown reasons now the extender connected via wifi to my MacBook Pro 16 inches running Catalina keep getting disconnected every 5-10 minutes. I am truly angry! I cannot work like that!I have tried several workaround like assign a static IP address to the extender. No luck. I have downgraded the firmware of Orbi to previous version. No changes (than I have reverted to latest firmware again). I have enable and disable AX (according to Netgear technical support tip), again no changes.I am totally lost.

What Firmware version is currently loaded?What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too? Are you referring to the RBR as the 1 AP and the RBS as the extenders? 200 sq meters maybe too small to have the RBR and 1 RBS all running at the same time. What is the distance between the router and 📡 satellite(s)? 30 feet or more is recommended in between RBR and RBS📡 to begin with depending upon building materials when wirelessly connected. https://kb.netgear.com/31029/Where-should-I-place-my-Orbi-satellite 📡 What happens if you turn OFF both RBS and just run the RBR alone? Any Wifi Neighbors near by? If so, how many?

The internet provider is Telecom Italy (TIM). The hub producer is ZTE model X388. I have the latest firmware for the hub.The router is connected via ethernet with the Orbi access point (only 1/4 feet away). Than the extenders are connected to the Orbi. They are about 40 feet away. Please note: signal is very good (!). Also according to Orbi, the coverage of my apartment is perfect since in terms of square meters this solution is optimized to 325 square meters (mine is 200!).The firmware for my Orbi is V4.6.5.14_2.0.54.Again I have not more than 6 visibile networks in my area and my own is the strongest and the others are quite far away and they also use a different channel.

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-NAThttps://kb.netgear.com/30187/How-to-fix-issues-with-Double-NATCouple 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 https://kb.netgear.com/000061277/Which-features-are-disabled-on-my-Orbi-router-when-it-is-set-to-AP-Modehttps://kb.netgear.com/19863/Ping-Test-to-determine-Optimal-MTU-Size-on-Router Also the distance between the modem and RBR should be 3 to 6 feet from each other.

Thanks for your help but there is a BUT: I have a security alarm system in the house with video cams and sensors and everything has been connected to the TIM hub via wifi. So if I disable the wifi the house is not protected any more. Which is something I want to avoid.Question: previously the TIM hub had both the Band Steering and the Easy Mesh enabled since the hub is also a certified 6+ device. Now I have disabled the Band Steering on the TIM hub. Maybe this will help? Shall I keep active the Easy Mesh on the TIM hub?Also, to narrow down the problem of being disconnected all the time, I have assigned through the orbi web browser interface a reserved static IP address to my 2 extenders (thanks to Orbi technical support).

You may have too much wifi singnals going on that is causing Noise and Interferences with the Orbi RBS. This is not recommended. What channels is the TIM modem using on 2.4 and 5Ghz?

    Also the distance between the modem and RBR should be 3 to 6 feet from each other.
