I wanted to get a couple of pictures, one of the A Point after its crashed with the A Point Ethernet connected in AP mode.
And what I see on the network when the B point is connected to Ethernet when it first turns ON and syncs with the A Point.

And what I see on the network when the B point is connected to Ethernet when it first turns ON and syncs with the A Point. ARP storm?

I just put the A point online as main host router and then turned ON the B point connected Ethernet behind 4 Daisy Chained switches.
I see this ARP storm happened 3 times then has gone away:

I presume this maybe by design...
A Point>DGS-1100>DGS-108>DGS-105>DGS-105 in basement that the B point connects too.
I noticed that I could not get the iphone or pad to connect to Airport Extreme. I changed the SSID name to Airport then they connected. I changed back to Airport Extreme and they would not connect and found the A point at RED. I powered OFF the A point, Then I went down and removed the B Point from Ethernet and restarted the A point.
A point is WHITE again and devices are reconnected. Something with B point Ethernet connected maybe causing the A Point to not work right in router mode.
I had to run into town for a bit. I returned and system is still online. B Point is wireless connected though with a weak connection. Why I'm hoping to Ethernet connect the B point in the basement...I'll try again to connect the B Point via Ethernet. I'll try and capture logs if the A point remains connectable.
Update 10/6/2020:I found that it was not the A point that was crashing or stopping. It was the upstream non D-Link gateway modem I had the 2202 system connected too. I tried a different non D-Link MESH system and it also causes problems at the gateway modem. I how have the 2202 system configured in AP Mode behind a different non D-Link router and the entire system is working fine with the B point ethernet connected behind 3 daisy chained DGS 1 series switches. I've contacted the Mfr of the non D-Link gateway modem about the problem seen on there modem.
