Not in this case. My sniffs on the network show a working DHCP server (I can watch other stations discover and request successfully); it just doesn't respond to the DHCP Discover packets sent from the N800. That makes me think that the discover packets are malformed since this happens on multiple networks with multiple different DHCP servers. But when I examine the N800 discover packets, they look good to me (at least they decode properly in ethereal).
