Reference Manual for the NETGEAR 54 Mbps Wireless Access Point WG602v3

Shared Key. With Shared Key authentication, only those PCs that possess the correct authentication key can join the network. By default, IEEE 802.11 wireless devices operate in an Open System network.

Wired Equivalent Privacy (WEP) data encryption is used when the wireless devices are configured to operate in Shared Key authentication mode.

802.11 Authentication

The 802.11 standard defines several services that govern how two 802.11 devices communicate. The following events must occur before an 802.11 Station can communicate with an Ethernet network through an access point, such as the one built in to the WG602v3:

1.Turn on the wireless station.

2.The station listens for messages from any access points that are in range.

3.The station finds a message from an access point that has a matching SSID.

4.The station sends an authentication request to the access point.

5.The access point authenticates the station.

6.The station sends an association request to the access point.

7.The access point associates with the station.

8.The station can now communicate with the Ethernet network through the access point.

An access point must authenticate a station before the station can associate with the access point or communicate with the network. The IEEE 802.11 standard defines two types of authentication: Open System and Shared Key.

Open System Authentication allows any device to join the network, assuming that the device SSID matches the access point SSID. Alternatively, the device can use the “ANY” SSID option to associate with any available Access Point within range, regardless of its SSID.

Shared Key Authentication requires that the station and the access point have the same WEP Key to authenticate. These two authentication procedures are described below.

Open System Authentication

The following steps occur when two devices use Open System Authentication:

1.The station sends an authentication request to the access point.

WG602v3 specifications

The NETGEAR WG602v3 is a wireless access point designed primarily for home and small office environments. As part of the NETGEAR family of networking devices, the WG602v3 ensures reliable and secure wireless connectivity, making it an essential component for users who require a seamless internet experience.

One of the main features of the NETGEAR WG602v3 is its support for the IEEE 802.11g wireless standard, which allows for data transfer rates of up to 54 Mbps. This standard ensures compatibility with older 802.11b devices while providing enhanced performance for newer wireless devices. The WG602v3 operates in the 2.4 GHz frequency band, ensuring widespread coverage and the ability to penetrate walls and barriers, making it suitable for diverse environments.

Another significant characteristic of this access point is its user-friendly setup process. The WG602v3 includes an intuitive web-based user interface that allows users to configure settings with ease. This simplifies the installation process and enables users, even those with limited technical knowledge, to quickly establish a robust wireless network.

Security is paramount in today’s interconnected world, and NETGEAR has incorporated several security features into the WG602v3. The device supports Wi-Fi Protected Access (WPA and WPA2) encryption protocols, ensuring that users can secure their data and prevent unauthorized access. Additionally, the WG602v3 includes a MAC address filtering feature that further enhances network security by allowing only designated devices to connect to the network.

The WG602v3 is also equipped with a detachable antenna, allowing users to customize their wireless coverage based on their specific needs. This adaptability makes it easier to optimize the access point’s performance in different physical layouts. Furthermore, it supports Power over Ethernet (PoE), enabling installation in locations without an accessible power outlet, which is particularly useful in unconventional setups.

In summary, the NETGEAR WG602v3 wireless access point combines ease of use, robust security features, and flexibility in installation to provide reliable connectivity. Its compatibility with both 802.11g and b devices, combined with user-friendly configuration options, ensures that it meets the needs of various users, from casual home users to small office setups, making it a versatile solution for enhancing wireless networks.
