I have the same setup and it works. Make sure your base station and DHCP router/modem are connected to a hub via standard cable to the standard ports and not the uplink (or crossover) port. My graphite base station is a dumb bridge and IP's are assigned by the router/modem.

P.S. As an extra measure I also added the DNS servers of my ISP to the base stations Internet setting. DHCP should take care of that but I read somewhere it may be more reliable to manually enter it also.
