What Firmware version is currently loaded?
What is the Mfr and model# of the ISP modem the NG router is connected too?
Is the Orbi system operating in Router or AP mode?
Directly connect the Orbi base to the ISP modem to test with out the switch in the middle to see if anything changes. Possible bad switch, however I doubt it.
CAT is recomended LAN cable type between the modem orbi RBR and all other wired devices.

Current router firmware version is 2.3.5.30. I'm not sure if this automatically updates, but I can check for updates if that is advised?
The modern is a Cisco DPC3941T (Xfinity XB3)
Orbe system is operating in Router mode
I have previously tested the setup without the switch and it seems to work fine. Again though, the problem only occurs intermittently and sometimes infrequently.

Well your ISP modem is a modem and router.
Is the modem bridged or in router mode? Bridge is recommended...
This would be a double NAT 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- finnabbieJul 01, 2020Aspirant
Thanks.
The Xfinity router is currently in Router mode. When I first set the system up, I tried it in Bridge mode and my setup didn't work at all. I forget what the specific issues were but I can test it again. I will also try some of the other approaches and report back on how it goes.
