RBKE963 - DHCP/Connectivity Failure
I have the RBKE963B kit here in the house, one device on each floor at opposite ends of the property, the top floor is connected wired, the middle floor is wifi backhaul. The connectivity in between various parts of the house are XS508M switches.
Usually everything works fine, but every few weeks all devices connected via wired connections just stop working, if they have a DHCP lease they maintain their assigned IP until the lease expires, but if you release the lease or disconnect the device it will no longer get an IP address assigned.
A full reboot of the router and satellites and all devices is required to get things up and running again.
Has anyone else experienced anything similar?

What FW are you using?
CAT# LAN cable are you using? CAT6A STP is recommended if your using the 2.5Gb ports to connect the RBS with that switch.
V6.0.3.85_3.1.15 is the firmware in use. Cables are all CAT6A.
Take the router out of the equation and stick some manual IPs on my NAS and a laptop and connect it around the house at various points in the network and you get full 2.5Gbps throughput, between my desktops I get full 10Gbps, the runs are relatively short.
I'm tempted to remove DHCP from the Orbi and run it in a container on my NAS and see if thats any better. This only started happening when I got the new Orbi's in, previous mesh system has been fine for multiple years.
Something to try on your Orbi system that I do on mine. Set the DHCP IP address pool to 192.168.1.100 to .200.
For my NAS I set a static IP address ON the NAS to something outside of this pool size I use. I have two NAS. Both on statics and have zero DHCP issues. There always there and online at designated IPs
I'm waiting for my XS505M to arrive so I can play around on 10Gb.

I haven't seen this type of DHCP failure with my RBKE963 and its uptime has exceeded 2 or 3 weeks. What is the size of your DHCP range compared to the number of connected devices? Do you have lots of iOS or other devices that randomize their MAC address, possibly consuming more of your DHCP slots?

Range is about 200 addresses, they aren't being used up. That's not how the iOS feature works, it just generates a new MAC address for each WiFi network you join, it doesn't randomise it on the same network.
