Hi FURRYe38 ,
I've just posted a reply, but can't see it now...
I proceeded with a network restart, als did a network reset on the phone and disabled randomized mac. ~24 hours later, the problem occurred once again...
For your information, I am using CAT6a network cables; the modem is a SagemcomFast5359; and no factory reset since latest FW upgrade.

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-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
Try option #2 first...

Hi FURRYe38 ,
Understood, but my Orbi is already in AP mode and the WIFI of the ISP modem is off.

Try changing DNS on the ISP modem router to something else. Try Google or Cloudfare.
Orbi would not be blocking any apps while in AP mode. It's just passing thru data.

Hello FURRYe38 ,
1) Could you please advise whether the advanced wireless settings copied below are optimal? Note that AX is enabled as well.
2) What does the CTS / Threshold mean and what is the optimal value?
3) I recall having set the 2.4 GHz power to 50% to avoid mixing router (on 1st floor) and satellite (on 2nd floor) signals, but now I see the phone switching to mobile data few meters from the satellite (incl. walls).Thank you
