Wireless-N Gigabit Router with Storage Link
Chapter 1: Introduction
Welcome
The Wireless-N Gigabit Router with Storage Link is really four devices in one box. First, there's the Wireless
Access Point, which lets you connect to the network without wires. There's also a built-in 4-port full-duplex
10/100 Switch to connect your wired-Ethernet devices together. The Router function ties it all together and lets
your whole network share a high-speed cable or DSL Internet connection.
We've also included a Storage Link that lets you easily add gigabytes of storage space onto your network using
readily available USB 2.0 hard drives -- or plug in a USB flash disk for a convenient way to access your portable
data files. The built-in Media Server streams music, video, and photos from the attached storage device to any
UPnP compatible media adapter. And you can get to your files from anywhere in the world through the Internet.
The Access Point built into the Router uses the very latest wireless networking technology, Wireless-N (draft
802.11n). By overlaying the signals of multiple radios, Wireless-N's "Multiple In, Multiple Out" (MIMO) technology
multiplies the effective data rate. Unlike ordinary wireless networking technologies that are confused by signal
reflections, MIMO actually uses these reflections to increase the range and reduce "dead spots" in the wireless
coverage area. The robust signal travels farther, maintaining wireless connections up to 4 times farther than
standard Wireless-G.
With Wireless-N, the farther away you are, the more speed advantage you get. It works great with standard
Wireless-G and -B equipment, but when both ends of the wireless link are Wireless-N, the router can increase the
throughput even more by using twice as much radio band, yielding speeds up to 12 times as fast as standard
Wireless-G. But unlike other speed-enhanced technologies, Wireless-N can dynamically enable this
double-speed mode for Wireless-N devices, while still connecting to other wireless devices at their respective
fastest speeds. In congested areas, the "good neighbor" mode ensures that the Router checks for other wireless
devices in the area before gobbling up the radio band.
To help protect your data and privacy, the Router can encode all wireless transmissions with industrial-strength
256-bit encryption. It can serve as your network's DHCP Server, has a powerful SPI firewall to protect your PCs
against intruders and most known Internet attacks, and supports VPN pass-through. Configuration is a snap with
the web browser-based configuration utility.
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
different IP address for the Internet.
lan (local area network): The computers and
networking products that make up the network in
your home or office.
The incredible speed of Wireless-N makes it ideal for media-centric applications like streaming video, gaming,
and Voice over IP telephony, and gives you plenty of headroom to run multiple media-intense data streams
through the network at the same time, with no degradation in performance. With the Linksys Wireless-N Gigabit
Router with Storage Link at the center of your home or office network, you can easily add storage, share a highspeed Internet connection, files, printers and multi-player games, and run media-intensive applications at faster
than 10/100 wired network speeds, without the hassle of stringing wires!

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.
ssid (service set identifier): your wireless network’s name.
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 Gigabit Router with Storage Link, 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.
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.
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.

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

boosts the Router’s ability to catch all Wireless-N and Wireless-G transmissions but will severely decrease
performance.
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.

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.
