The DHCP and TCP/IP default values work for most users.
LAN TCP/IP Setup
These are advanced settings that you may configure if you are a network administrator and your network contains multiple routers. If you make any changes to these settings you will need to restart your computer(s) for the settings to take effect.
IP Address: Type the IP address of your router in dotted decimal notation (factory default: 192.168.1.1).
IP Subnet Mask: The subnet mask specifies the network number portion of an IP address. Your router will automatically calculate the subnet mask based on the IP address that you assign. Unless you are implementing subnetting, use 255.255.255.0 as the subnet mask (computed by the router).
Use Router As DHCP Server
The Router is set up by default as a DHCP (Dynamic Host Configuration Protocol) server, which provides the TCP/IP configuration for the all the computers that are connected to the router.
Unless told to change these settings by your ISP, leave the Use Router As DHCP Server check box selected.
If your ISP has you clear this check box, you must have another DHCP server within your network or else you must manually configure the computer.
Starting IP Address: This box specifies the first of the contiguous addresses in the IP address pool.
192.168.1.2 is the default start address.
Ending IP Address: This box specifies the last of the contiguous addresses in the IP address pool.
192.168.1.254 is the default ending address.
Address Reservation
When you specify a reserved IP address for a PC on the LAN, that PC will always receive the same IP address each time it accesses the DHCP server. Reserved IP addresses should be assigned to servers that require permanent IP settings.
To Reserve An IP Address:
Click the Add button.
Select the radio button of the Computer you wish to add from the Address Reservation Table.
If the Computer is not on the Address Reservation Table, enter the IP Address, MAC Address, and Device Name of the computer you wish to add.
Click the Add button when finished.
To Edit A Reserved IP Address:
Select the radio button next to the reserved address you want to edit.
Click the Edit button.
Edit the IP Address, MAC Address or Device Name.
Click the Accept button when finished.
To Delete A Reserved IP Address:
Select the radio button next to the reserved address you want to delete.
Click the Delete button.
To Save Or Cancel Changes
Click Apply to save the new settings to the router.
