Some of these settings may be required by your ISP. Verify with your ISP before making any changes.
Router Name. In this field, you can type a name of up to 39 characters to represent the Router.
Host Name/Domain Name. These fields allow you to supply a host and domain name for the Router. Some ISPs, usually
cable ISPs, require these names as identification. You may have to check with your ISP to see if your 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. The
default setting, Manual, allows you to enter the largest packet size that will be transmitted. The recommended size, entered
in the Size field, is 1492. You should leave this value in the 1200 to 1500 range. To have the Router select the best MTU for
packet: a unit of data sent over a network
your Internet connection, select Auto.
Network Setup

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)
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.
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 time is up, the user will be automatically assigned a new dynamic IP address. The default is 0 minutes,
which means one day.
