192.168.1.1 (the default) than the Start IP address must be 192.168.1. 2 or higher.
—Specify an End IP address. The End IP Address is the last address the DHCP server can issue. The ending address cannot exceed a subnet limit of 254. The maximum IP address for a router using the default address is 192.168.1.254. If the DHCP server runs out of DHCP addresses, users will not get access to network resources.
—Specify a Lease Time. The Lease Time is the amount of time a network user will be allowed connection to the Router with their current dynamic IP address. The amount of time is in units of seconds; the default value is 3600 seconds (1 hour).
Note: If you change the start or end values, make sure the values are still within the same subnet as the router's IP address. For example, if the router's IP address is 192.168.1.1 (the default), and you change the DHCP Start and End IP addresses to be 192.128.1.2 and 192.128.1.100, you will not be able to communicate with the router if your PC has DHCP enabled.
In addition to the DHCP server feature, the router supports the DHCP relay function. When the router is configured as DHCP server, it assigns the IP addresses to the LAN clients. When the router is configured as DHCP relay, it is responsible for forwarding the requests and responses negotiating between the DHCP clients and the server.
If the DHCP server and relay are turned off, you must configure the IP address, subnet mask and DNS settings of every computer on your network. Do not assign the same IP address to more than one computer. Your router must be on the same subnet as the computers.
The Apply button will temporarily save these settings. To make the change permanent, click on Tools (at the top of the page) and select System Commands. At the System Commands page, click on Save All.
Changing the Router's IP address
Your router's default IP address and subnet mask are 192.168.1.1 and 255.255.255.0, respectively. This subnet mask allows the router to support 254 users. Since the DHCP server issues a maximum of 255 addresses, there is not much advantage to changing the subnet mask to increase the number of addresses. Further, remember that if you change your router’s IP address and you have DHCP enabled, the DHCP configuration must reside within the same subnet.
The default gateway is the routing device used to forward all traffic that is not addressed to a station within the local subnet. Your ISP will provide you with the default gateway address.
The Hostname can be any alphanumeric word beginning with a letter and containing no spaces. The domain name is used to in conjunction with the host name to uniquely identify the router.
