Setup is performed through the Wireless tab.
Router Address
This presents both the Router’s IP Address, Subnet Mask,
and URL Address as seen by your network. The default
Router IP address is 192.168.1.1, and the default URL
address is http://wrt400n.com.
Router IP Address
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, make sure there is no other
DHCP server on your network.
Network Address Server Settings (DHCP)
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 select Disabled (no other DHCP
features will be available).
Starting IP Address Enter a value for the DHCP server
to start with when is suing 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 computers 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.
Static DNS (1-3) 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. If you wish to use another,
enter that IP Address in one of these fields. You can enter up
to three DNS Server IP Addresses here. The Router will use
these for quicker access to functioning DNS servers .
WINS The Windows Internet Naming Service (WINS)
manages each computer’s interaction with the Internet. If
you use a WINS server, enter that server’s IP Address here.
Otherwise, leave this blank.
DHCP Reservation Click DHCP Reservation if you want
to assign a fixed local IP address to a MAC address.
DHCP Reservation
You will see a list of DHCP clients with the following
information: Client Name, Interface, IP Address, and MAC
Address. Click the Select checkbox to reserve a client’s IP
address. Then click Add Clients.
If you want to manually assign an IP address, enter the
client’s name in the Enter Client Name field. Enter the IP
address you want it to have in the Assign IP Address field.
Make sure the IP address is between the starting DHCP
server’s IP address and maximum number of DHCP users
range. Enter its MAC Address in the To This MAC Address
field. Click Add.
A list of DHCP clients and their fixed local IP addresses will
be displayed at the bottom of the screen. If you want to
remove a client from this list, click Remove.
