Reference Manual for the NETGEAR WG102 ProSafe 802.11g Wireless Access Point

•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 WG102:

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.

WG102 specifications

The NETGEAR WG102 is a robust and versatile wireless access point designed to enhance network connectivity in a variety of environments, from small businesses to larger enterprise settings. This device is well-regarded for its ease of use, reliable performance, and a feature set that caters to both basic and advanced networking needs.

One of the key features of the WG102 is its support for the IEEE 802.11g standard, which provides data rates of up to 54 Mbps. This makes it suitable for high-speed internet access and seamless data transfer for users connected to the network. Additionally, the WG102 is backward compatible with the 802.11b devices, ensuring that existing hardware can be integrated into the network without issues, thereby protecting investment in older technology.

The WG102 also excels in its deployment flexibility. With Power over Ethernet (PoE) support, installation becomes significantly easier, as the access point can receive power through the Ethernet cable, eliminating the need for additional power outlets. This feature is particularly advantageous in locations where power supply access is limited or where aesthetic considerations are key.

Security is a vital aspect of any network, and the WG102 does not disappoint. It supports Wi-Fi Protected Access (WPA and WPA2) for secure wireless communications, ensuring that user data is encrypted and protected from potential threats. The device also features WEP encryption, allowing users to implement various security measures based on their specific needs.

The WG102's management capabilities include a web-based interface, enabling administrators to configure settings easily and monitor network performance.
