Using the Web-Based Advanced User Interface

Using the Broadcast SSID Feature

Note: This advanced feature should be employed by advanced users only.

For security, you can choose not to broadcast your network’s SSID. Doing so

will keep your network name hidden from computers that are scanning for the

presence of wireless networks. To turn off the broadcast of the SSID, remove

the check mark from the box next to “Broadcast SSID”, and then click “Apply

Changes”. The change is immediate. Each computer now needs to be set to

connect to your specific SSID; an SSID of “ANY” will no longer be accepted.

Refer to the documentation of your wireless network adapter for information

on making this change.

Protected Mode Switch

As part of the 802.11g specification, Protected mode ensures proper operation

of 802.11g clients and access points when there is heavy 802.11b traffic in

the operating environment. When Protected mode is ON, 802.11g scans for

other wireless network traffic before it transmits data. Therefore, using this

mode in environments with HEAVY 802.11b traffic or interference achieves

best performance results. If you are in an environment with very little—or

no—other wireless network traffic, your best performance will be achieved

with Protected mode OFF.

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 (Wired Equivalent Privacy) 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 Ativa 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 combination of numbers and letters from A–F and

0–9. For 64-bit WEP, you must enter 10 hex keys. For 128-bit WEP, you must

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 Router uses this

passphrase to generate your WEP keys, but different hardware manufacturers

might have different methods on generating the keys. If you have multiple

vendors’ equipment in your network, the easiest thing to do is to use the hex

WEP key from your Router or access point and enter it manually into the hex

WEP key table in your Router’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 vendor’s website. There are two

types of WPA security, WPA-PSK (no server) and WPA (with radius server).

WPA-PSK (no server)

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.

Sharing the Same Network Keys

Most Wi-Fi products ship with security turned off. So once you have your

network working, you must activate WEP or WPA and make sure your

wireless networking devices are sharing the same network key.
