Thank you for choosing the Linksys by Cisco Wireless-N
Home Router. The Router lets you access the Internet via
a wireless connection or through one of its four switched
ports. You can also use the Router to share resources
such as computers, printers and files. A variety of security
features help to protect your data and your privacy
while you are online. Security features include WPA2
security, a Stateful Packet Inspection (SPI) firewall, and
NAT technology. Configuring the Router is easy using the
provided browser–based utility.
Front Panel
1, 2, 3, 4 (Blue) These numbered LEDs,
corresponding with the numbered ports on the
Router’s back panel, serve two purposes. If the
LED is continuously lit, the Router is successfully
connected to a device through that port. A
flashing LED indicates network activity over
that port.
Wi-Fi Protected Setup Button If you have
client devices, such as wireless adapters, that
support Wi-Fi Protected Setup, then you can
use Wi-Fi Protected Setup to automatically
configure wireless security for your wireless
network.

Chapter 2 Wireless Security Checklist

Wireless-N Home Router
Chapter 2:
Wireless Security Checklist
Wireless networks are convenient and easy to install, so
homes with high-speed Internet access are adopting them
at a rapid pace. Because wireless networking operates by
sending information over radio waves, it can be more
vulnerable to intruders than a traditional wired network.
Like signals from your cellular or cordless phones, signals
from your wireless network can also be intercepted. Since
you cannot physically prevent someone from connecting
to your wireless network, you need to take some additional
steps to keep your network secure.
1. Change the default wireless
network name or SSID
Wireless devices have a default wireless network name
or Service Set Identifier (SSID) set by the factory. This
is the name of your wireless network, and can be up
to 32 characters in length. Linksys wireless products
use linksys as the default wireless network name. You
should change the wireless network name to something
unique to distinguish your wireless network from other
wireless networks that may exist around you, but do not
use personal information (such as your Social Security
number) because this information may be available for
anyone to see when browsing for wireless networks.
2. Change the default password
For wireless products such as access points and routers,
you will be asked for a password when you want to change
their settings. These devices have a default password set
by the factory. The Linksys default password is admin.
Hackers know these defaults and may try to use them
to access your wireless device and change your network
settings. To thwart any unauthorized changes, customize
the device’s password so it will be hard to guess.
3. Enable MAC address filtering
Linksys routers give you the ability to enable Media Access
Control (MAC) address filtering. The MAC address is a
unique series of numbers and letters assigned to every
networking device. With MAC address filtering enabled,
wireless network access is provided solely for wireless
devices with specific MAC addresses. For example, you can
specify the MAC address of each computer in your home
so that only those computers can access your wireless
network.
4. Enable encryption
Encryption protects data transmitted over a wireless
network. Wi-Fi Protected Access (WPA/WPA2) and Wired
Equivalent Privacy (WEP) offer different levels of security
for wireless communication.
A network encrypted with WPA/WPA2 is more secure
than a network encrypted with WEP, because WPA/WPA2
uses dynamic key encryption. To protect the information
as it passes over the airwaves, you should enable the
highest level of encryption supported by your network
equipment.
WEP is an older encryption standard and may be the
only option available on some older devices that do not
support WPA.
General Network Security Guidelines
Wireless network security is useless if the underlying
network is not secure.
•Password protect all computers on the network and
individually password protect sensitive files.
•Change passwords on a regular basis.
•Install anti-virus software and personal firewall
software.
•Disable file sharing (peer-to-peer). Some applications
may open file sharing without your consent and/or
knowledge.
Additional Security Tips
•Keep wireless routers, access points, or gateways away
from exterior walls and windows.
•Turn wireless routers, access points, or gateways
off when they are not being used (at night, during
vacations).
•Use strong passphrases that are at least eight characters
in length. Combine letters and numbers to avoid using
standard words that can be found in the dictionary.

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 Basic Rate is not the actual rate of
data transmission. If you want to specify the Router’s rate
of data transmission, configure the Transmission Rate
setting.) 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 Auto, when the Router can transmit at
all standard wireless rates (1-2 Mbps, 5.5 Mbps, 11 Mbps,
18 Mbps, and 24Mbps). Select 1-2Mbps for use with older
wireless technology. Select All, when the Router can

Beacon Interval Enter a value between 1 and 65,535
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 is 100 milliseconds.
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, 2347, 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. The RTS
Threshold value should remain at its default value of
2347.

Forwarding
The Port Range Forwarding screen allows you to set up
public services on your network, such as web servers,
ftp servers, e-mail servers, or other specialized Internet
applications. (Specialized Internet applications are any
applications that use Internet access to perform functions
such as videoconferencing or online gaming. Some Internet
applications may not require any forwarding.)
When users send these types of requests to your network via
the Internet, the Router will forward those requests to the
appropriate servers (computers). Before using forwarding,
you should assign static IP addresses to the designated
servers (use the DHCP Reservation feature on the Basic Setup
screen; refer to DHCP Reservation, page 7).
If you need to forward all ports to one computer, click the
DMZ tab.

The DMZ feature allows one network computer to be
exposed to the Internet for use of a special-purpose
service such as Internet gaming or videoconferencing.
DMZ hosting forwards all the ports at the same time to
one computer. The Port Range Forwarding feature 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.
Applications and Gaming > DMZ

Wireless-N Home Router
Appendix A:
Troubleshooting
Your computer cannot connect to the Internet.
Follow these instructions until your computer can connect
to the Internet:
•Make sure that the Router is powered on. The Power
LED should be lit and not flashing.
•If the Power LED is flashing, then power off all of
your network devices, including the modem, Router,
and computers. Then power on each device in the
following order:
1. Cable or DSL modem
2. Router
3. Computer
•Check the cable connections. The computer should
be connected to one of the ports numbered 1-4 on
the Router, and the modem must be connected to the
Internet port on the Router.
The modem does not have an Ethernet port.
The modem is a dial-up modem for traditional dial-up
service. To use the Router, you need a cable/DSL modem
and high-speed Internet connection.
You cannot use the DSL service to connect manually to
the Internet.
After you have installed the Router, it will automatically
connect to your Internet Service Provider (ISP), so you no
longer need to connect manually.
The DSL telephone line does not fit into the Router’s
Internet port.
The Router does not replace your modem. You still need
your DSL modem in order to use the Router. Connect the
telephone line to the DSL modem, and then insert the
setup CD into your computer. Click Setup and follow the
on-screen instructions.
When you double-click the web browser, you are
prompted for a username and password. If you want to
get rid of the prompt, follow these instructions.
Launch the web browser and perform the following steps
(these steps are specific to Internet Explorer but are similar
for other browsers):
1. Select Tools > Internet Options.
2. Click the Connections tab.
3. Select Never dial a connection.
4. Click OK.
The Router does not have a coaxial port for the cable
connection.
The Router does not replace your modem. You still need
your cable modem in order to use the Router. Connect
your cable connection to the cable modem, and then
insert the setup CD into your computer. Click Setup and
follow the on-screen instructions.
The computer cannot connect wirelessly to the network.
Make sure the wireless network name or SSID is the same
on both the computer and the Router. If you have enabled
wireless security, then make sure the same security
method and key are used by both the computer and the
Router.
You need to modify the settings on the Router.
Open the web browser (for example, Internet Explorer or
Firefox), and enter the Router’s IP address in the address
field (the default IP address is 192.168.1.1). When
prompted, enter the password to the Router (the default is
admin). Click the appropriate tab to change the settings.
