Today, I exchanged the WAG120N for a Netgear DM111P, just a modem, not a router. Same setup configuration: modem connected to dsl line, ethernet cable from modem (NetgearDM111P) to the slot marked "WAN" on the RV110W, another ethernet cable from RV110W to my PC. Same result - type in 192.168.1.1 and get taken to the admin page for "Netgear DM111P"
Clearly, there's a serious PEBKAC situation here, but what exactly is it? Any help resolving this will be very gratefully received.
