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 modem routers
away from exterior walls and windows.
• Turn wireless routers, access points, or modem routers
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 and access points 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.

Advanced Configuration
After setting up the Access Point with the Setup Wizard
(located on the CD-ROM), the Access Point will be ready
for use. However, if you want to change its advanced
settings, use the Access Point’s browser-based utility. This
chapter describes each page of the utility and each page’s
key functions. You can access the utility via a web browser
on a computer networked with the Access Point.
The browser-based utility has these main tabs: Setup,
Wireless, Administration, and Status. Additional tabs will
be available after you click one of the main tabs.
How to Access the Browser-based Utility
In order to access the browser-based utility, you need a
web browser and the IP address of the Access Point.
If the Access Point is connected to a network with a DHCP
server (usually the network router), then the Access Point will
obtain its IP address from the DHCP server.
To determine
your router’s DHCP client table. (Refer to your router’s
documentation for instructions on accessing the DHCP
client table.)
the Access Point’s IP address, look for it in
NOTE: If the password request screen does not
appear, wait two minutes and try again.
Setup > Basic Setup
The first screen that appears is the Basic Setup screen.
Use this screen to change the browser-based utility’s
language, or to change the Access Point’s wired, Ethernet
network settings.
If you cannot find the Access Point’s IP address, then reset
the Access Point. Press the Reset button on the Access
Point for approximately five seconds, using a straightened
paper clip. This will restore the Access Point’s factory
default settings. The Access Point will then request an
IP address from the DHCP server (usually the network
router).
After you have determined the Access Point’s IP address,
launch your web browser, and enter the Access Point’s IP
address in the Address field. Press Enter.
A password request screen appears. (Non-Windows XP
users will see a similar screen.) Leave the User name field
blank. Enter the password you created during the Setup
Wizard. If you did not create a new password, use the
default password admin. (You can set a new password
from the Administration >Management screen.) Click OK
to continue.

Wireless-N and Wireless-A devices in your network, keep
the default setting, Mixed.
Network Mode (2.4 GHz) From this drop-down menu,
you can select the wireless standards running on your

Network Name (SSID)
shared among all points in a wireless network. The SSID
must be identical for all devices in the wireless network. It
is case-sensitive and must not exceed 32 characters (use
any characters on the keyboard). Make sure this setting is
the same for all points in your wireless network. For added
security, you should change the default SSID (linksys) to a
unique name.
Channel Width For best performance in a Wireless-N
network, select 40MHz only. For Wireless-A, Wireless-G,
and Wireless-B networking only, or if you are not sure
which option to use, keep the default, 20MHz only.
