desired. It is recommended that you leave this value in the 1200 to 1500 range. For most DSL users, it is
recommended to use the value 1492. By default, MTU is set at 1500 when disabled.
Network Setup
The Network Setup section allows you to change the Router's local network settings.
Router IP
The values for the Router's Local IP Address and Subnet Mask are shown here. In most cases, keeping the default
values will work.
Local IP Address. The default value is 192.168.15.1.
Subnet Mask. The default value is 255.255.255.0.
Network Address Server Settings (DHCP)
These settings allow you to configure the Router's Dynamic Host Configuration Protocol (DHCP) server function.
The Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to
each computer on your network. Unless you already have one, it is highly recommended that you leave the Router
enabled as a DHCP server.
DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, set the
Router's DHCP option to Disable. If you disable DHCP, remember to assign a static IP address to the Router.
Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the
default IP address for the Router is 192.168.15.1, the Start IP Address must be 192.168.15. 2 or greater, but
smaller than 192.168.15.254. The default Start IP Address is 192.168.15.100.
Maximum Number of DHCP Users (Optional). Enter the maximum number of PCs that you want the DHCP server
to assign IP addresses to. This number cannot be greater than 253. The default is 50.
Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the
Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be "leased"
this dynamic IP address. After the dynamic IP address has expired, the user will be automatically assigned a new
dynamic IP address. The default is 0 minutes, which means one day.
Static DNS 1-2. The Domain Name System (DNS) is how the Internet translates domain or website names into
Internet addresses or URLs. Your ISP will provide you with at least one DNS Server IP Address. You can enter up to
two DNS Server IP Addresses here. The Router will use these for quicker access to functioning DNS servers.
