Router IP
This presents both the Router’s IP Address and Subnet Mask as seen by your network.
Network Address Server Settings (DHCP)
Figure 6-9: 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.
Figure 6-10: Network Address Server Settings
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.
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, type that IP Address in one of these fields. You can type 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 PC’s interaction with the Internet. If you use
a WINS server, enter that server’s IP Address here. Otherwise, leave this blank.
Time Setting
Change the time zone in which your network functions from this pull-down menu. (You can even automatically
adjust for daylight savings time.)

The Setup Tab - Advanced Routing
This tab is used to set up the Router’s advanced functions. Operating Mode allows you to select the type(s) of
advanced functions you use. Dynamic Routing will automatically adjust how packets travel on your network. Static
Routing sets up a fixed route to another network destination.
Operating Mode. Select the mode in which this Router will function. If this Router is hosting your network’s
connection to the Internet, select Gateway. If another Router exists on your network, select Router. When Router is
chosen, Dynamic Routing will be enabled.
Dynamic Routing. This feature enables the Router to automatically adjust to physical changes in the network’s
layout and exchange routing tables with the other router(s). The Router determines the network packets’ route
based on the fewest number of hops between the source and the destination. This feature is Disabled by default.
From the drop-down menu, you can also select LAN & Wireless, which performs dynamic routing over your
Ethernet and wireless networks. You can also select WAN, which performs dynamic routing with data coming from
the Internet. Finally, selecting Both enables dynamic routing for both networks, as well as data from the Internet.
Figure 6-14: Setup Tab - Advanced Routing (Gateway)
Static Routing. To set up a static route between the Router and another network, select a number from the Static
Routing drop-down list. (A static route is a pre-determined pathway that network information must travel to reach a
specific host or network.) Enter the information described below to set up a new static route. (Click the Delete This
Entry button to delete a static route.)
Enter Route Name. Enter a name for the Route here, using a maximum of 25 alphanumeric characters.
Destination LAN IP. The Destination LAN IP is the address of the remote network or host to which you want to
assign a static route.
Subnet Mask. The Subnet Mask determines which portion of a Destination LAN IP address is the network
portion, and which portion is the host portion.
Default Gateway. This is the IP address of the gateway device that allows for contact between the Router and
the remote network or host.
Interface. This interface tells you whether the Destination IP Address is on the LAN & Wireless (Ethernet and
wireless networks), the WAN (Internet), or Loopback (a dummy network in which one PC acts like a network—
necessary for certain software programs).

The Wireless Tab - Wireless Security
The Wireless Security settings configure the security of your wireless network. There are four wireless security
mode options supported by the Router: WPA Pre-Shared Key, WPA RADIUS, RADIUS, and WEP. (WPA stands for WiFi Protected Access, which is a security standard stronger than WEP encryption. WEP stands for Wired Equivalent
Privacy, while RADIUS stands for Remote Authentication Dial-In User Service.) These four are briefly discussed
here. For detailed instructions on configuring wireless security for the Router, turn to “Appendix B: Wireless
Security.”
IMPORTANT: If you are using WPA, always
remember that each device in your wireless
network MUST use the same WPA method
and shared key, or else the network will not
function properly.
WPA Pre-Shared Key. WPA gives you two encryption methods, TKIP and AES, with dynamic encryption keys.
Select the type of algorithm, TKIP or AES. Enter a WPA Shared Key of 8-63 characters. Then enter a Group Key
Renewal period, which instructs the Router how often it should change the encryption keys.
WPA RADIUS. This option features WPA used in coordination with a RADIUS server. (This should only be used
when a RADIUS server is connected to the Router.) First, select the type of WPA algorithm you want to use, TKIP
or AES. Enter the RADIUS server’s IP Address and port number, along with a key shared between the Router and
the server. Last, enter a Key Renewal Timeout, which instructs the Router how often it should change the
encryption keys.

RADIUS. This option features WEP used in coordination with a RADIUS server. (This should only be used when a
RADIUS server is connected to the Router.) First, enter the RADIUS server’s IP Address and port number, along
with a key shared between the Router and the server. Then, select a Default Transmit Key (choose which Key to
use), and a level of WEP encryption, 64 bits 10 hex digits or 128 bits 26 hex digits. Last, either generate a
WEP key using the Passphrase or enter the WEP key manually.
IMPORTANT: If you are using WEP
encryption, always remember that each
device in your wireless network MUST use
the same WEP encryption method and
encryption key, or else your wireless network
will not function properly.
WEP. WEP is a basic encryption method, which is not as secure as WPA. To use WEP, select a Default Transmit Key
(choose which Key to use), and a level of WEP encryption, 64 bits 10 hex digits or 128 bits 26 hex digits. Then
either generate a WEP key using the Passphrase or enter the WEP key manually.
