Welcome
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.
lan (local area network): The computers and
networking products that make up the network in
your home or office.
nat (network address translation): NAT technology
translates IP addresses of a local area network to a
different IP address for the Internet.
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.

Network Topology
Wireless-N Broadband Router
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
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 wireless-
equipped 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.
ssid (service set identifier): your wireless network’s name.
ad-hoc: a group of wireless devices
communicating directly to each other (peer-to-
peer) without the use of an access point.

Router IP
The Router’s Local IP Address and Subnet Mask are shown here. In most cases, you should keep the defaults.
Local IP Address. The default value is 192.168.1.1.
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.

devices will be able to communicate with the Router but not with each other. To use this function, click Enabled.
AP Isolation is disabled by default.
Authentication Type. The default is set to Auto, which allows either Open System or Shared Key authentication
to be used. Select Shared Key if you only want to use Shared Key authentication (the sender and recipient use a
WEP key for authentication).
Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the
Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so
they know which rates will be used. The Router will also advertise that it will automatically select the best rate
for transmission. The default setting is Default, when the Router can transmit at all standard wireless rates
(1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless
technology, and All, when the Router can transmit at all wireless rates.
Transmission Rate. The rate of data transmission should be set depending on the speed of your wireless
network. You can select from a range of transmission speeds, or you can select Auto to have the Router
automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between the Router and a wireless client. The default setting is
Auto.
N Transmission Rate. The rate of data transmission should be set depending on the speed of your Wireless-N
networking. You can select from a range of transmission speeds, or you can select Auto to have the Router
automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will
negotiate the best possible connection speed between the Router and a wireless client. The default setting is
Auto.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode’s default setting is Auto. The Router will
automatically use CTS Protection Mode when your Wireless-N and Wireless-G products are experiencing severe
problems and are not able to transmit to the Router in an environment with heavy 802.11b traffic. This function
boosts the Router’s ability to catch all Wireless-N and Wireless-G transmissions but will severely decrease

Beacon Interval. Enter a value between 20-1000 milliseconds. The Beacon Interval value indicates the
frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize the wireless
network. The default value is 100.
DTIM Interval. This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message
(DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and
multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast
and multicast messages. The default value is 1.
Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into
multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor
reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.
RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2346, is
recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS)
frame to acknowledge the right to begin transmission. In most cases, keep its default value of 2346.

Wireless-N Broadband Router
The Applications & Gaming Tab - DMZ
The DMZ screen allows one local user to be exposed to the Internet for use of a special-purpose service such as
Internet gaming and videoconferencing. DMZ hosting forwards all the ports at the same time to one PC. The Port
Range Forwarding is more secure because it only opens the ports you want to have opened, while DMZ hosting
opens all the ports of one computer, exposing the computer to the Internet.
Any PC whose port is being forwarded must have its DHCP client function disabled and should have a new static
IP address assigned to it because its IP address may change when using the DHCP function.
DMZ
To use this feature, select Enabled. To disable DMZ hosting, select Disabled.
Source IP Address. If you want any IP address to be the source, select Any IP Address. If you want to specify an
