DHCP Settings
By default, the router functions as a Dynamic Host Configuration Protocol (DHCP) server, allowing it to assign IP, DNS server, and default gateway addresses to all computers connected to the router’s LAN. The assigned default gateway address is the LAN address of the router. IP addresses is assigned to the attached PCs from a pool of addresses specified in this screen. Each pool address is tested before it is assigned to avoid duplicate addresses on the LAN.
For most applications, the default DHCP and TCP/IP settings of the router are satisfactory. See the online document listed in "Internet Networking and TCP/IP Addressing:" in Appendix B for an explanation of DHCP and information about how to assign IP addresses for your network.
Use Router as DHCP Server
If another device on your network will be the DHCP server, or if you will manually configure the network settings of all of your computers, clear the Use Router as DHCP Server check box on the LAN IP Setup screen. Otherwise, leave it selected.
Specify the pool of IP addresses to be assigned by filling in the Starting IP Address and Ending IP Address fields. These addresses should be part of the same IP address subnet as the router’s LAN IP address. Using the default addressing scheme, you should define a range between 192.168.0.2 and 192.168.0.254, although you might want to save part of the range for devices with fixed addresses.
