Encryption/Security
Securing your Wi-Fi Network
Here are a few different ways you can maximize the security of your wireless
network and protect your data from prying eyes and ears. This section is
intended for the home, home office, and small office user. At the time of this
User Manual’s publication, there are three encryption methods available.

WEP (Wired Equivalent Privacy)
WEP is a common protocol that adds security to all Wi-Fi-compliant
wireless products. WEP was designed to give wireless networks the
equivalent level of privacy protection as a comparable wired network.
64-Bit WEP
64-bit WEP was first introduced with 64-bit encryption, which includes
a key length of 40 bits plus 24 additional bits of system-generated
data (64 bits total). Some hardware manufacturers refer to 64-bit
as 40-bit encryption. Shortly after the technology was introduced,
researchers found that 64-bit encryption was too easy to decode.

128-Bit WEP
As a result of 64-bit WEP’s potential security weaknesses, a more secure
method of 128-bit encryption was developed. 128-bit encryption includes a key
length of 104 bits plus 24 additional bits of system-generated data (128 bits
total). Some hardware manufacturers refer to 128-bit as 104-bit encryption.
Most of the new wireless equipment in the market today supports
both 64-bit and 128-bit WEP encryption, but you might have
older equipment that only supports 64-bit WEP. All Belkin wireless
products will support both 64-bit and 128-bit WEP
Encryption Keys
After selecting either the “64-bit” or “128-bit WEP” encryption mode, it is
critical that you generate an encryption key. If the encryption key is not
consistent throughout the entire wireless network, your wireless networking
devices will be unable to communicate with one another on your network
and you will not be able to successfully communicate within your network.
You can enter your key by typing in the hex key manually, or you can
type in a passphrase in the “Passphrase” field and click “Generate”
to create a key. A hex (hexadecimal) key is a mixture of numbers
and letters from A–F and 0–9. For 64-bit WEP, you need to enter
10 hex keys. For 128-bit WEP, you need to enter 26 hex keys.
For instance:
AF 0F 4B C3 D4
= 64-bit WEP key
C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7
= 128-bit WEP key
The WEP passphrase is NOT the same as a WEP key. Your wireless card
uses this passphrase to generate your WEP keys, but different hardware
manufacturers might have different methods for generating the keys. If
you have equipment from multiple vendors in your network, you can use
the hex WEP key from your Router or access point and enter it manually
into the hex WEP key table in your wireless card’s configuration screen.
WPA (Wi-Fi Protected Access)
WPA (Wi-Fi Protected Access) is a new Wi-Fi standard that was designed to
improve upon the security features of WEP. To use WPA security, the drivers and
software of your wireless equipment must be upgraded to support WPA. These
updates will be found on the wireless vendors’ websites. There are two types
of WPA security: WPA-PSK (no server) and WPA (with 802.1x radius server).

WPA-PSK (no server)
This method uses what is known as a Pre-Shared key as the Network
key. A Network key is basically a password that is between eight and
63 characters long. It can be a combination of letters, numbers, or
characters. Each client uses the same Network key to access the network.
Typically, this is the mode that will be used in a home environment.
WPA (with 802.1x radius server)
With this system, a radius server distributes the Network key to the
clients automatically. This is typically found in a business environment.
WPA2
The Router features WPA2, which is the second generation of WPA based
802.11i standard. It offers higher level of wireless security by combining
advanced network authentication and stronger AES encryption method.
WPA2 Requirements
IMPORTANT: In order to use WPA2 security, all your computers and
wireless client adapters must be upgraded with patches, driver, and client
utility software that supported WPA2. At the time of this User Manual’s
publication, a couple security patches are available, for free download,
from Microsoft. These patches work only with the Windows XP operating
system. Other operating systems are not supported at this time.
For Windows XP computer that does not have Service Pack 2 (SP2), a file
from Microsoft called “Windows XP Support Patch for Wireless Protected
Access (KB 826942)” is available for free download at http://support.
microsoft.com/?kbid=826942
For Windows XP with Service Pack 2, Microsoft has released a free
download to update the wireless client components to support WPA2
(KB893357). The update can be download from:
com/default.aspx?scid=kb;en-us;893357
IMPORTANT:
You also need to ensure that all your wireless client cards /
adapters support WPA2, and that you have downloaded and installed the
latest driver. Most of the Belkin Wireless cards have update driver available
for download from the Belkin support site: www.belkin.com/networking.

Sharing the Same Network Keys
Most Wi-Fi products ship with security turned off. So once you have
your network working, you need to activate WEP or WPA and make sure
your wireless networking devices are sharing the same Network key.

Using a Hexadecimal Key
A hexadecimal key is a mixture of numbers and letters from A–F and 0–9. 64-bit
keys are five two-digit numbers. 128-bit keys are 13 two-digit numbers.
For instance:
AF 0F 4B C3 D4
= 64-bit key
C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7
= 128-bit key
In the boxes below, make up your key by writing in two characters
between A–F and 0–9 in each box. You will use this key to program the
encryption settings on your Router and your wireless computers.
The Wireless G
Desktop Network
Card cannot access
the network because
it is using a different Network key than the Network key
that is configured on the Wireless G Router.

Note to Mac users:
Original Apple AirPort® products support 64-bit
encryption only. Apple AirPort 2 products can support 64-bit or 128-bit
encryption. Please check your product to see which version you are using.
If you cannot configure your network with 128-bit encryption, try 64-bit
encryption.
WEP Setup
1.
Select “WEP” from the drop-down menu.
2.
Select “WEP Mode” of 64-bit or 128-bit
3.
After selecting your “WEP mode”, you can enter your key by typing in
the hex key manually.
A hex (hexadecimal) key is a mixture of numbers and letters from A–F and
0–9. For 64-bit WEP, you need to enter 10 hex keys. For 128-bit WEP, you
need to enter 26 hex keys.
For instance:
AF 0F 4B C3 D4
= 64-bit key
C3 03 0F AF 0F 4B B2 C3 D4 4B C3 D4 E7
= 128-bit key
