I am adding some routers to my home network to improve weak signals in some areas. My primary router is WNDR 4000, and that one is connected directly to my cable modem. My first additional router is a WRT54G running dd-wrt. I have the ethernet cable in one of the regular jacks (not the internet jack). I set it up with the same SSID and password with the same encryption as the WNDR4000, disabled DHCP, and put it on a different IP address. Everything is working, or so it seems. I can connect to it using the new IP address, but when I view the router settings, it says the WAN address is 0.0.0.0. I don't think that is right, is it? When I hit the DHCP renew it still comes back with 0.0.0.0. I tried setting the WAN address to a static address once, and that made it so I couldn't connect to the router at all and I had to 30-30-30 reset it again to get it going again.
Is it normal for a router to have a WAN IP address of 0.0.0.0 when configured this way?
