Try disabling Port Forwarding on the cameras. Any see if anything differs.

Daisy Chain is used for piggy backing satellites and should be disabled if you use wire connected satellites. There has been a known issue on recent FW for Orbi that Daisy Chain check box seems to be working in reverse and that putting a check mark in Daisy Chain in the GUI, acutally disables the feature rather than enabling it.

UPnP port forwardimg is already disabled on all of the cameras. Something else I've noticed that seems unusual is that all of the cameras are connecting to my 2.4GHz band. I have 5 DCS-2630L's that are dual band capable, but they are not connecting on the 5GHz band. That would seem to make more sense to me, they would get better throughput that way.

I have seen up to 4 cameras connect at once on the DNV-312L UI, and it does seem that my two DCS-2330L cameras are staying connected more of the time but they still drop out now and then.

Note that using the MyDlink Lite app, I can get to most of my cameras, but there is a significant delay before the video comes up. This happens regardless of whether I am remote or on my home WiFi.

Here's all the firmware / agent versions and so on - everything is at the latest to my knowledge:

CH01 Camera: DCS 2630L
Firmware Version 1.05.02
Hardware Version A
Agent Version 2.2.0-b52

CH02 Camera: DCS 2630L
Firmware Version 1.05.02
Hardware Version A
Agent Version 2.2.0-b52

CH03 Camera: DCS 2630L
Firmware Version 1.05.02
Hardware Version A
Agent Version 2.2.0-b52

CH04 Camera: DCS 2630L
Firmware Version 1.05.02
Hardware Version A
Agent Version 2.2.0-b52

CH05 Camera: DCS 2630L
Firmware Version 1.05.02
Hardware Version A
Agent Version 2.2.0-b52

CH06 / CH07: No Cameras on these channels

CH08 Camera: DCS 2330L
Firmware Version   1.14.03
Hardware Version   A
Agent Version   2.1.0-b02

CH09 Camera: DCS 2330L
Firmware Version   1.14.03
Hardware Version   A
Agent Version   2.1.0-b02

I have now enabled UPnP Port Forwarding on all cameras, and used unique external ports for each camera. The goal here is to prevent the build up of UPnP port forwarding rules being created for various random external port numbers.

I have also lowered the video profiles on all DCS-2630L cameras as follows:

Profile 1: 1920x1080, 10 FPS, 256Kbps
Profile 2: 1280x720, 5 FPS, Low quality
Profile 3: 640X352, 10 FPS, 128Kbps

The DCS-2330L cameras have their video profiles configured as follows:

Profile 1: Mode H.264, 1280x720 Frame Size, 1280x720 View Area, maximum frame rate 4, Fixed quality at Standard
Profile 2: Mode H.264, 640x360 Frame Size, 640x360 View Area, maximum frame rate 4, Fixed quality at Standard
Profile 3 is not configurable.

The goal was to try to dramatically reduce the amount of traffic on my WiFi from the cameras.

I have also taken the camera on channel 8, a DCS-2330L, and temporarily used a hard-wired ethernet connection. Connectivity in the DNR-312L UI has been completely fixed by this - that camera stays connected, and updates fairly quickly. This suggests to me that this is a WiFi connectivity problem, as using a hard-wired connection eliminates the connectivity dropping and reconnecting.

I also tried changing a router setting to set the 2.4GHz transmit power control to 75%, in hopes of getting some of the DCS-2630L cameras to connect on the 5GHz band. That did not work - they are all still connecting to 2.4GHz. I am more than willing to put another Orbi Satellite in to get better 5GHz coverage, but one of the cameras is less than 6 feet from the current satellite, and it is connecting to the 2.4GHz band. Is there some sort of built-in preference for 2.4GHz? If so, it would be nice if that were configurable, so the camera could be told to prefer 5GHz over 2.4GHz.

I just realized I left out the most important version information - the DNR-312L's info!

Agent Version 2.2.0-b39n
Firmware Version v1.07.10
Firmware Date Jul 26 2018
Current NVR Device Pack v1.12.05
Device Pack Date Jul 26 2018

Huge breakthrough tonight - I came across information on how to get the Netgear Orbi to use different SSID's for the 2.4GHz and 5GHz bands, and after applying those changes, and reconfiguring the cameras to connect to the 5GHz band, they have stopped dropping their connections sporadically. So it would appear that the problem was related to both bands using the same SSID - the cameras were getting confused somehow, and were perhaps cycling between the two bands. Not real sure. But by getting the bands on separate SSID's, things are working now. I have one camera that isn't connected right now, but I think that's a fluke. I need to do a reset on it and configure it again. Can't find a paperclip to do that (I know, ridiculous). Will work on that tomorrow.

For those interested, and who feel comfortable leveraging semi-documented functionality of the Netgear Orbi router, and are technically savvy, here's the link for how to get the bands on different SSID's:
