Thank you for choosing the Linksys by Cisco Wireless-N
PCI Adapter with Dual-Band. Using the latest wireless
networking technology, the Adapter adds or upgrades
wireless connectivity on your notebook computer.
To help protect your data and privacy, you can use
industrial-strength WPA2 encryption to protect your
wireless connection. The included Setup Wizard will walk
you through configuring the Adapter to your network’s
settings, step by step.
Bracket Features
The Adapter is a PCI board attached to a standard-sized
bracket. An optional, low-profile bracket is also included.
There are two screws that attach the PCI board to its 1.
standard-sized bracket. Remove both screws.
Use the two screws to attach the PCI board to the 2.
low-profile bracket.
ANT The antenna connector is a connection
point for one of the Adapter’s antennas.
LINK/ACT (Green) The LED lights up when
the Adapter is connected to a wireless
network. The LED flashes when the Adapter
is sending or receiving data over the wireless
connection.
ANT The antenna connector is a connection
point for one of the Adapter’s antennas.
Use of the Low-Profile Bracket (Optional)
If your computer is low-profile, then attach the PCI board
to the low-profile bracket before you install the Adapter in
your computer.
To install the Adapter, run the Setup Wizard on the 3.
Setup CD. For more information, refer to the Quick
Installation.

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.
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.
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.
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.

The Linksys Wireless Manager is used to configure the
Adapter. The Wireless Manager lets you search for available
wireless networks, establish or terminate a connection
with a wireless network, and save a wireless network’s
settings.
How to Access the Wireless Manager
After you have installed the Adapter, the Linksys Wireless
Manager icon appears in the system tray of your computer.
If the Adapter is connected to a wireless network, the icon
will have green bars (the exact number of green bars
varies depending on the network’s signal strength). If the
Adapter is not connected to a wireless network, the icon
will have gray bars with a red X.
