Have you tried setting a DHCP address reservation [by MAC address]? xr500 has the default pool of addresses the entire class C range. That's silly. Trim that down and set the reservation outside that pool.
default is 192.168.1.2 through 192.168.1.254
you will be changing 254 to 230
reserve an address for hue between 231 and 250.
Explain.
Why would it?
