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
