XR500 DHCP issues
I have an xr500 which I bought about a year ago. When I got gigabit fiber internet. I've added a lot of 2.4ghz only smart switches, Echo devices, TVs, and cameras. At this point I'm at around 49 devices total.
I was having a lot of issues with power outages or router restarts where afterward I could only get about 6-10 devices connected without going to the breaker box and powering up a section of the house at a time.
Looking at the router logs during a restart I see a bunch of DOS attack warnings, which seem to be the router assuming a DOS attack due to so many DHCP requests.
In order to try to alleviate the issue and add some security for my network, I bought an r6700 and cascaded it over an av1200 powerline adapter on 192.168.2.x as its own DHCP server with 39 of the devices, while the xr500 is at 192.168.1.x.
My r6700 now runs one 2.4ghz SSID for all my IOT devices, with up reservations set for everything to try to reduce the load from DHCP on reconnect. The XR500 is running smart connect on a separate SSID for everything bandwidth hungry like TVs computers and smart phones.
Coverage isn't too bad, though the outdoor cameras and garage opener sometimes drop.
My questions are:
1. Does ip reservation actually help
2. Would I be better served using a dedicated mesh setup for iot in place of the single r6700? I'm not sure how DHCP is managed with mesh. Is it distributed load, or managed by a single node?
3. Is there a better configuration using the existing hardware?

- To answer your questions:
1. It can help in some cases yes but not for everyone. I do still suggest it. Moreover what would help if possible is to give the XR a static IP upstream if at all possible.
2. It's really up to you, either setup should be fine, mesh would be better for coverage if that is a concern. I believe that the router would assign an IP to the master node and any additional nodes would receive an IP from the master node.
3. If you want the R6700 to handle DHCP then I can't think of a better configuration with that currently. I assume you use the XR for its features for gaming etc and for QoS across the network so that needs to be upstream of the R6.
