SSID - The SSID is the network name shared among all devices 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 alphanumeric

characters, which may be any keyboard character (do not use any spaces). Make sure this setting is the same

for all devices in your wireless network. For added security, Linksys recommends that you change the default

SSID (linksys) to a name of your choice.

To search for available wireless networks, click the

Site Survey

button.

Site Survey

The

Site Survey

screen, shown in Figure 7-4 shows all the wireless networks detected by the Bridge and their

general information. You can use this screen to connect to one of these networks.

For each wireless network detected, the following information is displayed:

•

SSID - The network name. To join a wireless network, click its SSID.

•

MAC Address - The MAC address of the network’s access point.

•

Channel - The channel setting.

•

Signal Strength (%) - The percentage of wireless signal strength.

•

Mode - The type of wireless standard, network mode, and status of WEP encryption.

•

Click the

Network Type - Choose a wireless operating mode for the Bridge. Keep the default setting,

Infrastructure

, if

you want your wireless-equipped device to communicate with computers and other devices on your wired

network using a wireless access point. Select

Ad-Hoc

button if you want multiple wireless-equipped devices

to communicate directly with each other.

If you chose Ad-Hoc mode, then select the correct operating channel for your network from the

Channel

drop-

down menu. This should match the channel setting of the other devices in your wireless network.

Select the appropriate network mode. Keep the default,

The Security screen, as shown in Figure 7-5, will appear. From the drop-down menu, select one of the four

wireless security modes supported by the Bridge: WEP, RADIUS, WPA RADIUS, and WPA Pre-Shared Key,. (WEP

stands for Wired Equivalent Privacy, RADIUS stands for Remote Authentication Dial-In User Service, and WPA

stands for Wi-Fi Protected Access, which is a security standard stronger than WEP encryption) .The four

security modes are briefly discussed here. For detailed instructions on configuring wireless security for the

Bridge, turn to “Appendix B: Wireless Security.”

WEP

Use the

WEP

screen, shown in Figure 7-5, to configure the WEP encryption for the Bridge. Select a

Default

Transmit Key

(choose which Key to use), and a level of

WEP Encryption

,

64 bits (10 hex digits)

or (

128 bits

26 hex digits)

. Then either generate a

WEP Key

using a

Passphrase

or enter the WEP key manually.

•

Default Transmit Key - Select which WEP key (1-4) will be used when the Bridge sends data. Make sure

the other wireless-equipped devices are using the same key.

•

WEP Encryption - In order to use WEP encryption, select

64-Bit (10 hex digits)

or

128-Bit (26 hex

digits)

from the drop-down menu.

•

Passphrase - Instead of manually entering WEP keys, you can enter a Passphrase. This Passphrase is

used to generate one or more WEP keys. It is case-sensitive and should not be longer than 16

alphanumeric characters. (The Passphrase function is compatible with Linksys wireless products only. If

you want to communicate with non-Linksys wireless products, you will need to enter your WEP key

manually on the non-Linksys wireless products.) After you enter the Passphrase, click the

Generate

button to create WEP key(s).

•

Keys 1-4 - If you are not using a Passphrase, then you can enter one or more WEP keys manually.

In each key field, manually enter a set of values. (Do not leave a key field blank, and do not enter all

zeroes. These are not valid key values.) If you are using 64-bit WEP encryption, then each key must

consist of exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, then

each key must consist of exactly 26 hexadecimal characters in length. Valid hexadecimal characters are

“0”-“9” and “A”-“F”.

NOTE:

Make sure that your security choice

matches the security choice of the wireless

network you want to join. Otherwise, the

connection will fail.

RADIUS

This option features WEP used in coordination with a RADIUS server. (This should only be used when a

RADIUS server is connected to the Router.) It offers three authentication methods: MD5, TLS, and TTLS.

EAP Type

MD5

Select a Default Key (choose which Key to use), and a level of WEP encryption,

64 bits 10 hex digits

or

128

bits 26 hex digits

. Then either generate a WEP key using a Passphrase or enter the WEP key manually. (See

Figure 7-6.)

•

Default Transmit Key

Select which WEP key (1-4) will be used when the Bridge sends data. Make sure

that the receiving device (wireless client) is using the same key.

•

WEP Encryption. An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect

your wireless data communications. WEP uses 64-bit or 128-bit keys to provide access control to your

network and encryption security for every data transmission. To decode data transmissions, all devices in

a network must use an identical WEP key. Higher encryption levels offer higher levels of security, but due

to the complexity of the encryption, they may decrease network performance. Select

64 bits (10 hex

digits)

or

128 bits (26 hex digits)

.

•

Passphrase. Instead of manually entering WEP keys, you can enter a passphrase. This passphrase is used

to generate one or more WEP keys. It is case-sensitive and should not be longer than 32 alphanumeric

characters. (This Passphrase function is compatible with Linksys wireless products only and cannot be

used with Windows XP Zero Configuration. If you want to communicate with non-Linksys wireless

products or Windows XP Zero Configuration, make a note of the WEP key generated in the Key 1 field, and

enter it manually in the wireless client.) After you enter the Passphrase, click the

Generate

button to

create WEP keys.

•

Keys 1-4. WEP keys enable you to create an encryption scheme for wireless network transmissions. If you

are not using a Passphrase, then manually enter a set of values. (Do not leave a key field blank, and do not

enter all zeroes; they are not valid key values.) If you are using 64-bit WEP encryption, the key must be

exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, the key must be

exactly 26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.
