Product Overview
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
Power (Green) The Power LED lights up
and will stay on while the Router is powered
on. When the Router goes through its selfdiagnostic 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
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.
Internet (Green) The Internet LED lights up
when there is a connection made through the
Internet port.
Secure Easy Setup (Orange/White) The Cisco
logo is the Router’s 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 Router’s
Setup Wizard CD-ROM and follow the onscreen instructions to use SecureEasySetup.
Back Panel
Reset There are two ways to reset the Router’s
factory defaults. Either press and hold the
Reset Button, for approximately five seconds,
or restore the defaults from Administration
> Factory Defaults in the Router’s web-based
utility.
Internet The Internet port is where you will
connect your cable or DSL Internet connection.
1, 2, 3, 4 These Ethernet ports (1, 2, 3, 4) connect
the Router to PCs on your wired network and
other Ethernet network devices.
Power The Power port is where you will
connect the power adapter.

Wireless Security Checklist
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.
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.
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.
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.

Chapter 3: Advanced Configuration
After setting up the Router with EasyLink Advisor or the
Setup Wizard (located on the CD-ROM), the Router will be
ready for use. However, if you’d like to change its advanced
settings, use the Router’s web-based utility. This chapter
describes each web page of the utility and each page’s key
functions. You can access the utility via a web browser on
a computer connected to the Router.
The web-based utility has these main tabs: Setup,
Wireless, Security, Access Restrictions, Applications &
Gaming, Administration, and Status. Additional tabs will
be available after you click one of the main tabs.
NOTE: When first installing the Router, you
should use the Setup Wizard on the Setup
CD-ROM. If you want to configure advanced
settings, use this chapter to learn about the
web-based utility.
Advanced Configuration
How to Access the Web-Based Utility
To access the web-based utility, launch the web browser on
your computer, and enter the Router’s default IP address,
192.168.1.1, in the Address field. Then, press Enter.
A password request screen will appear. (Non-Windows XP
users will see a similar screen.) Leave the User name field
blank. The first time you open the Web-based utility, use
the default password admin. (You can set a new password
from the Administration tab’s Management screen.) Click
the OK button to continue.

•
Automatic Configuration - DHCP
By default, the Router’s Internet Connection Type is set
to Automatic Configuration - DHCP, which should be
kept only if your ISP supports DHCP or you are connecting
through a dynamic IP address. (This option usually applies
to cable connections.)
