We just got an Netgear WNCE2001 - and the need to support it.
Basically, its an Wireless -> Ethernet Converter which does bridge an WIFI Network to an LAN / Ethernet Connector.
You need to install it via WDS System or - plug it into an PC / Laptop, DHCP Client on and configure it via Webbrowser before using it on an "dump" ethernet-only device. Problem: The device itself asks for an IP Adress (to be configured after inital stage) and the connected Ethernet Client does ask itself again - some DHCP Servers don't like that behavior, as far as it seems. So, our workaround was following: Giving the WNCE2001 an static assigned IP by the DHCP Server and "blocking" another IP for the Client. The Client has been configured statically and does now work as it was intended to be.

Notes:
"First" Client Adress internal DHCP Server of the WNCE2001 does offer before inital Configuration: 192.168.1.100
IP of the WNCE2001: 192.168.1.251
