Cell phone calls disconnect when on Wi-fi

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, IPv6 and Set 20/40Mhz Coexistence to 40Mhz only. Set Short preamble instead of Long preamble modes. Save settings and reboot the router and satellite(s).

Be sure that CTS and RTS values are changed to 2347 under Advanced Tab/Advanced Settings/Wireless Settings

Any progress on this?

I have noticed that if I have my WiFi on my iPhone XS and someone calls , the call gets immediately disconnected. If I try to make a call & the WiFi is on, as soon as someone picks up, the call is disconnected.

Not a problem when the WiFi is turned off. Not a problem when I’m on someone else’s WiFi.

Thoughts? Some kind of restriction from the Orbi router? (I’ve had this iPhone for almost 2 years and this is a new problem.)
