When my N12D uses "Automatic Configuration-DHCP" to connect to Wan. My Device can use Wi-Fi connect to the router, but no internet. I need to connect a PC to the Lan port of the router, so that my device can successfully connect to the Internet.

What settings do I need to change to successfully use "Automatic Configuration-DHCP" to access the Internet?

(N12D DD-WRT Version：v42681)
(Wan IP obtained using DHCP：192.168.1.106)

Change router lan IP on basic settings page under network to 192.168.2.1. The default IP is 192.168.1.1, which conflicts with the WAN IP address.

My router lan IP is set to 192.168.3.1.
But the Gateway of my router is set to 192.168.1.1. Do I need to change？

You normally do not need to set the gateway IP address, unless your router is in switch or wired AP mode (router, not gateway).
