Wireless-G Broadband Router with SpeedBooster
Chapter 1:
Product Overview
Thank you for choosing the Linksys Wireless-G Broadband
Router with SpeedBooster. The Router lets you access
the Internet via a wireless connection, broadcast at up
to 54 Mbps, 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 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
Secure Easy Setup (Orange/White) The Cisco
logo is the Routers SecureEasySetup button. It
lights up and will stay orange when the Router
is powered on. The color orange indicates that
the Router is not using the SecureEasySetup
feature, while the color white indicates that the
Router is using the SecureEasySetup feature.
When the Router enters SecureEasySetup
mode, the Cisco logo will turn white and
start flashing. After the Router has generated
the SSID and WPA Shared Key, the Cisco
logo will stop flashing and stay white.
To clear the SSID and WPA Shared Key, press and
hold down the Cisco logo for five seconds. The
Cisco logo will flash slowly as the Router resets
itself. The Cisco logo will turn orange to indicate
a successful reset.
NOTE: SecureEasySetup is a feature that makes
it easy to set up your wireless network. If you
have SecureEasySetup devices, run the Routers
Setup Wizard CD-ROM and follow the on-
screen instructions to use SecureEasySetup.
Power (Green) The Power LED lights up
and will stay on while the Router is powered
on. When the Router goes through its self-
diagnostic mode during every boot-up, this
LED will flash. When the diagnostic is complete,
the LED will be solidly lit.
DMZ (Green) The DMZ LED indicates when
the DMZ function is being used. This LED will
remain lit as long as DMZ is enabled.
WLAN (Green) The WLAN LED lights up when
the wireless feature is enabled. If the LED is
flashing, the Router is actively sending or
receiving data over the network.
1, 2, 3, 4 (Green) These numbered LEDs,
corresponding with the numbered ports on the
Routers back panel, serve two purposes. If the
LED is continuously lit, the Router is successfully
connected to a device through that port. A

Wireless Security Checklist

Wireless-G Broadband Router with SpeedBooster
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 devices 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
Equivalency Privacy (WEP) offer different levels of security
for wireless communication. Currently, devices that are
Wi-Fi certified are required to support WPA2, but are not
required to support WEP.
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.

Authentication Type The default is set to Auto, which
allows either Open System or Shared Key authentication
to be used. With Open System authentication, the sender
and the recipient do NOT use a WEP key for authentication.
With 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. 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.
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 value is Auto.
CTS Protection Mode CTS (Clear-To-Send) Protection
Mode should remain disabled unless you are having severe
problems with your Wireless-G products not being able
to transmit to the Router in an environment with heavy
802.11b traffic. This function boosts the Routers ability
to catch all Wireless-G transmissions but will severely
decrease performance.
Frame Burst Enabling this option should provide your
network with greater performance, depending on the
manufacturer of your wireless products. To turn off the
Frame Burst option, select Disable. The default is Enable.
Beacon Interval The default value is 100. 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.
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.
AP Isolation This isolates all wireless clients and wireless
devices on your network from each other. Wireless devices
will be able to communicate with the Router but not with
each other. To use this function, select On. AP Isolation is
turned Off by default.
Secure Easy Setup This feature allows you to enable or
disable the SecureEasySetup feature. Select Disable to
disable the feature and turn off the buttons light. The
feature is enabled by default.
