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 Routers 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 Routers 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.
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 servers 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

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 Wi-
Fi 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.
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 servers 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. Figure 6-17: Wireless Tab - Wireless Security
(WPA Pre-Shared Key)
Figure 6-18: Wireless Tab - Wireless Security
