Wireless-N Broadband Router
Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Wireless-N Broadband Router. The Wireless-N Broadband Router will allow
you to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely and with a
greater range of up to three times farther than standard Wireless-G.
How does the Wireless-N Broadband Router do all of this? A router is a device that allows access to an Internet
connection over a network. With the Wireless-N Broadband Router, this access can be shared over the four
switched ports or via the wireless broadcast.
Use wireless security to secure your wireless network while the whole network is protected through a Stateful
Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology. The Router also offers VPN
passthrough and other features, which can be configured through the easy-to-use, browser-based utility.
The incredible speed of Wireless-N makes it ideal for media-centric applications like streaming video and Voice
over IP (VoIP) telephony, so your network can handle multiple data streams at the same time, with no degradation
in performance.
But what does all of this mean?
Networks are useful tools for sharing computer resources. You can access one printer from different computers
and access data located on another computer's hard drive. Networks are even used for playing multiplayer video
games. So, networks are not only useful in homes and offices, they can also be fun.
PCs on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called “wired”.
PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called
a WLAN, or Wireless Local Area Network. The Wireless-N Broadband Router bridges wireless and wired networks,
allowing them to communicate with each other.
Linksys recommends using the Setup Wizard on the Setup CD-ROM for first-time installation of the Router. If you
do not wish to run the Setup Wizard, then use the instructions in this Guide to help you connect the Router and
configure it. These instructions should be all you need to get the most out of the Wireless-N Broadband Router.
spi (stateful packet inspection) firewall: a technology
that inspects incoming packets of information before
allowing them to enter the network.
firewall: Security measures that protect the
resources of a local network from intruders.
nat (network address translation): NAT technology
translates IP addresses of a local area network to a

Chapter 2: Planning Your Wireless Network
Network Topology
A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each
computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same
frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the
same wireless network.
Ad-Hoc versus Infrastructure Mode
ssid (service set identifier): your wireless network’s name.
Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure
and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an
access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other.
Choosing between these two modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.
If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral,
such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure
mode. The basis of Infrastructure mode centers around a wireless router or an access point, such as the
Wireless-N Broadband Router, which serves as the main point of communications in a wireless network. The
Router transmits data to PCs equipped with wireless network adapters, which can roam within a certain radial
range of the Router. You can arrange the Router and multiple access points to work in succession to extend the
roaming range, and you can set up your wireless network to communicate with your Ethernet hardware as well.
If the wireless network is relatively small and needs to share resources only with the other computers on the
wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless
transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or
access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to
communicate with computers on a wired network. And, of course, communication between the wirelessequipped computers is limited by the distance and interference directly between them.
Network Layout
The Wireless-N Broadband Router has been specifically designed for use with your Wireless-N, Wireless-G, and
Wireless-B products. It will work with notebook adapters for your laptop computers, PCI adapters for your
infrastructure: a wireless network that is bridged
to a wired network via an access point.
ad-hoc: a group of wireless devices
communicating directly to each other (peer-topeer) without the use of an access point.

Subnet Mask. The default value is 255.255.255.0.
DHCP Server Setting
The Router can be used as a Dynamic Host Configuration Protocol (DHCP) server for your network. A DHCP server
automatically assigns an IP address to each computer on your network. Unless you already have one, it is highly
recommended that you leave the Router enabled as a DHCP server.
DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, set the
Router’s DHCP option to Disabled. If you disable DHCP, remember to assign a static IP address to the Router.
Start IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the default
IP address for the Router is 192.168.1.1, the Start IP Address must be 192.168.1. 2 or greater, but smaller than
192.168.1.254. The default Start IP Address is 192.168.1.100.
Maximum Number of Users (Optional). 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 dynamic IP address has expired, 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. 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) converts NetBIOS names to IP addresses. If you use a WINS
server, enter that server’s IP address here. Otherwise, leave this field blank.

The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain
name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other
server behind the Router.
Before you can use this feature, you need to sign up for DDNS service at one of two DDNS service providers,
DynDNS.org or TZO.com. If you do not want to use this feature, keep the default setting, Disable.
DDNS
DDNS Service
If your DDNS service is provided by DynDNS.org, then select DynDNS.org from the drop-down menu. If your
DDNS service is provided by TZO, then select TZO.com. The features available on the DDNS screen will vary,
depending on which DDNS service provider you use.
DynDNS.org
Username, Password, and Host Name. Enter the settings of the account you set up with DynDNS.org.
System. Select the DynDNS service you use: Dynamic, Static, or Custom.
Mail Exchange (Optional). Enter the address of your mail exchange server, so e-mails to your DynDNS
address go to your mail server.
Backup MX. This feature allows the mail exchange server to be a backup. To enable this feature, keep the
default, Enabled. To disable the feature, select Disabled. If you are not sure which setting to select, keep the
default, Enabled.
WildCard. This setting enables or disables wildcards for your host. For example, if your DDNS address is
myplace.dyndns.org and you enable wildcards, then x.myplace.dyndns.org will work as well (x is the
wildcard). To enable wildcards, keep the default, Enabled. To disable wildcards, select Disabled. If you are
not sure which setting to select, keep the default, Enabled.
Status. The status of the DDNS service connection is displayed here.

The Setup Tab - MAC Address Clone
A MAC address is a 12-digit code assigned to a unique piece of hardware for identification, like a social security
number. Some ISPs will require you to register a MAC address in order to access the Internet. If you do not wish
to re-register the MAC address with your ISP, you may assign the MAC address you have currently registered with
your ISP to the Router with the MAC Address Clone feature.
MAC Address Clone
To use MAC address cloning, select Enabled. Otherwise, keep the default, Disabled.
MAC Address. Enter the MAC Address registered with your ISP.
Clone My PC’s MAC. If you want to clone the MAC address of the PC you are currently using to configure the
Router, then click this button. The Router will automatically detect your PC’s MAC address, so you do NOT have to
call your ISP to change the registered MAC address to the Router’s MAC address. It is recommended that the PC
registered with the ISP is used to open the MAC Address Clone screen.
When you have finished making changes to this screen, click the Save Settings button to save the changes, or
