Security Options
. The selection of wireless security options can significantly affect your
network performance. The time it takes to establish a wireless connection can vary depending
on both your security settings and router placement.
WEP connections can take slightly longer to establish. Also, WEP, WPA-PSK, and WPA2-
PSK encryption can consume more battery power on a notebook computer, and can cause
significant performance degradation with a slow computer. Instructions for configuring the
security options can be found in
“Choosing Appropriate Wireless Security” on page 2-1
. A
full explanation of wireless security standards is available in the online document that you can
access from
“Wireless Networking Basics” in Appendix B
.

Configuring WEP Wireless Security
WEP Shared Key authentication and WEP data encryption can be defeated by a determined
eavesdropper using publicly available tools.
WEP offers the following options:
•
Automatic
. With the Automatic option, the router will try both Open System and Shared Key
authentication. Normally this setting is suitable. If it fails, select
Shared Key
. You can also
refer to your wireless adapter’s documentation to see what method to use.
•
Shared Key
. With Shared Key authentication, a wireless device must know the WEP key to
join the network. Select the encryption strength (64 or 128 bit data encryption). Manually
enter the key values, or enter a word or group of printable characters in the
Passphrase
field.
Manually entered keys
are not
case-sensitive, but passphrase characters
are
case-sensitive.
To configure WEP data encryption:
1.
Select
Wireless Settings
under Setup in the main menu.
2.
In the Security Options section, select
WEP
. The WEP options display.
Note:
If you use a wireless computer to configure WEP settings, you will be disconnected
when you click
Apply
. You must then either configure your wireless adapter to
match the wireless router WEP settings or access the wireless router from a wired
computer to make any further changes. Not all wireless adapter configuration
utilities support passphrase key generation.
