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).

section

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:

http://support.microsoft.

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

Select “WEP” from the drop-down menu.

Select “WEP Mode” of 64-bit or 128-bit

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
