broadband Internet service has been configured with a host and domain name. In most cases, leaving these
fields blank will work.
MTU. MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet
transmission. You should leave this value in the 1200 to 1500 range. To have the Router select the best MTU for
your Internet connection, select Auto. The default setting is Auto.
Network Setup
The Network Setup section changes the settings on the network connected to the Router's Ethernet ports.
Wireless Setup is performed through the Wireless tab.
Router IP
This presents both the Router's IP Address and Subnet Mask as seen by your network.
Network Address Server Settings (DHCP)

Figure 5-10: Router IP

The 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. If you choose to enable the Router's DHCP server option, you must configure all
of your network PCs to connect to a DHCP server (the Router), and make sure there is no other DHCP server on
your network.
DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you
don't want a DHCP server, then click the Disable radio button (no other DHCP features will be available).
Starting IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the
Router's default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller
than 192.168.1.253. The default Starting IP Address is 192.168.1.100.

Maximum Number of DHCP Users. 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.
