3. Choose your authentication method.

To set authentication for WG602 Wireless Access Point, select the

Open System or

Shared Key Authentication Type by selecting the radio button. All other devices using

this band must share this setting. Shared Key operation offers an increase in security over

an Open System operation.

4. Setup 802.11b/g WEP encryption security as needed.

For 802.11b/g, all four keys must have the same encryption level — 64-bit or 128-bit.

All devices in the network must have the same key values in for the selected encryption

key. The encryption key selected as the default determines the encryption level at which

the access point is transmitting.

For 64-bits encryption:

Hexadecimal: 10 hexadecimal digits in the range of "A-F", "a-f" and "0-9" (e.g.

11AA22BB33).

For 128-bits encryption:

Hexadecimal: 26 hexadecimal digits in the range of "A-F", "a-f" and "0-9" (e.g.

00112233445566778899AABBCC).

Passphrase:

You can enter a Passphrase to avoid manually entering WEP keys. It is case-sensitive.

5. When you are done, click the Apply button and then the Reboot button for the changes

to take effect.

Protecting Your Wireless Network

The absence of a physical connection between nodes makes wireless links vulnerable to

information theft. This chapter describes how to use the basic security features of the WG602

Wireless Access Point to protect your network.

Although your network traffic may already be encrypted, the security steps described here are

easy to perform.

Enabling Basic Wireless Access Security Features

There are several steps you can take to secure your wireless network:

• Change the factory default administrator password of the WG602.

• Place the WG602 in a location where it cannot be physically tampered with.

Security Configuration

To prevent unauthorized wireless stations from accessing data transmitted over the network, the

Security Settings screen of the Access Point Setup offers use of an authentication protocol as

well as data encryption, known as WEP (Wired Equivalent Privacy).

For a step-by-step treatment of security setup, see Enabling Basic Wireless Access Security Features

on page 18.

1. Use a browser to connect to the WG602.

2. Click Security Settings on the Access Point Setup menu and log in.

Configuration Description

RTS Threshold

Request to Send Threshold. The packet size that is used to

determine if it should use the CSMA/CD (Carrier Sense

Multiple Access with Collision Detection) mechanism or the

CSMA/CA mechanism for packet transmission. With the

CSMA/CD transmission mechanism, the transmitting station

sends out the actual packet as soon as it has waited for the silence

period. With the CSMA/CA transmission mechanism, the

transmitting station sends out an RTS packet to the receiving

station, and waits for the receiving station to send back a CTS

(Clear to Send) packet before sending the actual packet data.

Default: 2346

Fragmentation Length

This is the maximum packet size used for fragmentation.

Packets larger than the size programmed in this field will be

fragmented. The Fragment Threshold value must be larger

than the RTS Threshold value.

Default: 2346

Preamble Type

A long transmit preamble may provide a more reliable

connection or slightly longer range. A short transmit preamble

gives better performance.

Default: Long

DTIM

The Delivery Traffic Indication Message specifies the data

beacon rate between 1 and 16384.

Default: 1
