I'm trying to extend our Wi-fi by cabling a DIR-655 router to our internet gateway router, a DIR-880L. It will not connect, and the 655's log states: "The addressing of the Internet side learnt through DHCP conflicts with addressing for the LAN side. Internet communications will be disabled until you have changed the LAN side addressing to resolve the conflict." I can get an old Westell router and a newer Netgear router to connect (DHCP) with no difficulties. Any suggestions?
