yep it makes not difference if its wired or wireles. a DHCP server doesn't really know or care about wired or none wired it just cares in which (v)lan it destributes ip's to.

whether you expose that (v)lan to wired or wireless sidd's is indendant of the dhcp doing its thing.

next day edit: I didn't captured the fact of of trying to use the OC200 as DHCP service , the controller can't do this

  @mehmeh Oddly enough though, when the DHCP service is enabled on the wired network, wireless clients don't receive IP addresses. Is there some trick to this?

Topology here is a Netgear Nighthawk cellular hotspot (from AT&T) connected to a dumb switch, along with the OC200, and one EAP. A second EAP is remote (about 200') and meshed with the first. All is well when the Netgear's DHCP service is enabled, but disable it and enable the OC200's DHCP and clients don't receive addresses.

  @wrathskellar Are you sure the OC200 has a dhcp server in it?  Generally the controller configures the other components.  Those dhcp settings may only work if you are using an Omada gateway.

Nope, that's why I'm here. If it does, it doesn't work. If it doesn't, well, that section of the manual (section 4.3.2) and associated config pages could be made a whole lot clearer.

I must apologise,  I misread or didn't absorb the fact you wanted to use the OC200 as DHCP service, as other indicated the OC200 doesn't have that capability.
