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
1.Use a browser to connect to the WG602.
2.Click Security Settings on the Access Point Setup menu and log in.

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 —
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.

3 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. | 18 |
