The LAN Setup screen allows configuration of LAN IP services such as Dynamic Host 
Configuration Protocol (DHCP) and Routing Information Protocol (RIP).

The router is shipped preconfigured to use private IP addresses on the LAN side and to act 
as a DHCP server. The router’s default LAN IP configuration is:

LAN IP address. 192.168.1.1

Subnet mask. 255.255.255.0

These addresses are part of the designated private address range for use in private networks 
and are suitable for most applications. If your network requires a different IP addressing 
scheme, you can change these settings in the LAN Setup screen.

If you change the LAN IP address of the router while connected 
through the browser, you are disconnected. You will have to open a 
new connection to the new IP address and log in again.
