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 four

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, 128Bit

WEP was developed as a more secure method of encryption. 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

characters. For 128-bit WEP, you need to enter 26 hex characters.

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 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 radius server)

With this system, a radius server distributes the Network key to

the clients automatically. This is typically found in a business

environment. For a list of Belkin wireless products that support WPA,

please visit our website at

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.

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.

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 Characters.

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.

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.
