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
