LAN
You can configure the LAN IP address to suit your preference. Many users will find it convenient to use the default settings together with DHCP
service to manage the IP settings for their private network. The IP address of the Router is the base address used for DHCP. In order to use the
Router for DHCP on your LAN, the IP address pool used for DHCP must be compatible with the IP address of the Router. The IP addresses
available in the DHCP IP address pool will change automatically if you change the IP address of the Router.
To access the
Local Area Network (LAN) Setup
