Having problems with an existing DD-WRT (192.168.1.1 wired to an Asus RT-N66U router on 192.168.0.2. They are connected via a
CAT5e cable from the DD-WRT's LAN port to the Asus WAN port.

Asus: IP: 192.168.0.2 / Subnet 255.255.255.0 / Gateway 192.168.1.1 / DNS are the same as programmed on the DD-WRT. The Asus is configured in the Wireless router mode.

DD-WRT: IP 192.168.1.1 / Subnet 255.255.255.0 / Gateway is the proper IP as assigned by ISP.

I can connect via wireless to the Asus, however, cannot connect to Internet. Also, unable to ping to 192.168.1.1 from the Asus.

When I change the Asus routers mode to AP and let the router configure itself I can connect to the Internet, however, the router changes to 192.168.1.2 rather than 192.168.0.2. I want to separate the two subnets because I have an IP system on .1.

Dont know what I'm missing. Any help would be greatly appreciated. Thanks

Interfaces have to be on the same network in order to talk to each other, e.g., 192.168.1.0/24. The WAN port on the Asus should be set to 192.168.1.2 and connected to a port on the DD-WRT. Then you can use network 1921.168.0.0/24 and configure IP address 192.168.1.1 as the default Gateway. You'll also have to add a route on the DD-WRT to 192.168.0.0/24 via 192.168.1.2; that way the routers will know how to route traffic properly.
