Wireless Security Checklist
Chapter 2
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, routers, and
gateways, 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 and gateways 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.
Wireless-G Router for Mobile Broadband
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.
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.

Chapter 3:
Advanced Configuration
After setting up the Router with 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.
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 login screen will appear. (Non-Windows XP users will see
a similar screen.) Enter admin (the default) in both the User
name and Password fields. (You can set a new password on
the Administration tab’s Management screen.) Click OK to
continue.
