The DHCP service is being provided by your ISP router, all the Orbi is doing is forwarding those requests to that router.
Are the two Orbi units in the same place as they were before?
Is the ISP router wifi turned off?
Any evidence of poor speeds on the connections that are made?
One possibility is that the ISP router can't handle that many connections.

Um no. I switched the Orbi 850 from AP mode to Router mode and connected it directly to the ISP, no other router in between. I made it the DHCP, as is the norm for you ISP router. It is this functionality that is flaky as hell, failing within a few hours. Couldn't connect any new devices. Cannot configure any timers.
