Dup ip addrs can also occur if you've a DHCP range of ip addrs to auto-assign and another device has been manually assigned an ip addr from that DHCP range. If you're able to get in the OpenWRT mgmt. gui, there's an arp table in their somewhere that will list all the mac addrs and ip addrs pairs that the Buffalo sees on the network. You can also run the "arp -a" command on the windows device and see what mac & ip addrs pairs it sees on the network.
