Using the Reset Button to Restore Factory Default Settings

The Reset button (see

“WG302 rear panel” on page 2-7

) has two functions:

•

Reboot.

When pressed and released quickly, the WG302 will reboot (restart).

•

Reset to Factory Defaults.

This button can also be used to clear ALL data and restore ALL

settings to the factory default values.

To clear all data and restore the factory default values:

1.

Power off the WG302 and power it back on.

2.

Use something with a small point, such as a pen, to press the Reset button in and hold it in for

at least 5 seconds.

3.

Release the Reset button.

The factory default configuration has now been restored, and the WG302 is ready for use.

Wireless Networking Basics

This chapter provides an overview of Wireless networking.

Wireless Networking Overview

The WG302 Access Point conforms to the Institute of Electrical and Electronics Engineers (IEEE)

802.11b and 802.11g standards for wireless LANs (WLANs). On an 802.11b or g wireless link,

data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in

the unlicensed radio spectrum at 2.5GHz. The maximum data rate for the 802.11b wireless link is

11 Mbps, but it will automatically back down from 11 Mbps to 5.5, 2, and 1 Mbps when the radio

signal is weak or when interference is detected. The 802.11g auto rate sensing rates are 1, 2, 5.5, 6,

9, 12, 18, 24, 36, 48, and 54 Mbps.

The 802.11 standard is also called Wireless Ethernet or Wi-Fi by the Wireless Ethernet

Compatibility Alliance (WECA, see

http://www.wi-fi.net

), an industry standard group promoting

interoperability among 802.11 devices. The 802.11 standard offers two methods for configuring a

wireless network - ad hoc and infrastructure.

Infrastructure Mode

With a wireless Access Point, you can operate the wireless LAN in the infrastructure mode. This

mode provides wireless connectivity to multiple wireless network devices within a fixed range or

area of coverage, interacting with wireless nodes via an antenna.

In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet

data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple Access

Points via a wired Ethernet backbone can further extend the wireless network coverage. As a

mobile computing device moves out of the range of one access point, it moves into the range of

another. As a result, wireless clients can freely roam from one Access Point domain to another and

still maintain seamless network connection.

Ad Hoc Mode (Peer-to-Peer Workgroup)

In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed

points to the network - each node can generally communicate with any other node. There is no

Access Point involved in this configuration. This mode enables you to quickly set up a small

wireless workgroup and allows workgroup members to exchange data or share printers as

supported by Microsoft networking in the various Windows operating systems. Some vendors also

refer to ad hoc networking as peer-to-peer group networking.

In this configuration, network packets are directly sent and received by the intended transmitting

and receiving stations. As long as the stations are within range of one another, this is the easiest

and least expensive way to set up a wireless network.

Network Name: Extended Service Set Identification (ESSID)

The Extended Service Set Identification (ESSID) is one of two types of Service Set Identification

(SSID). In an ad hoc wireless network with no access points, the Basic Service Set Identification

(BSSID) is used. In an infrastructure wireless network that includes an access point, the ESSID is

used, but may still be referred to as SSID.

An SSID is a thirty-two character (maximum) alphanumeric key identifying the name of the

wireless local area network. Some vendors refer to the SSID as network name. For the wireless

devices in a network to communicate with each other, all devices must be configured with the

same SSID.

The ESSID is usually broadcast in the air from an access point. The wireless station sometimes can

be configured with the ESSID

ANY.

This means the wireless station will try to associate with

whichever access point has the stronger radio frequency (RF) signal, providing that both the access

point and wireless station use Open System authentication.

Authentication and WEP Data Encryption

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

eavesdropping and information theft. To provide a certain level of security, the IEEE 802.11

standard has defined these two types of authentication methods:

•

Open System

. With Open System authentication, a wireless computer can join any network

and receive any messages that are not encrypted.
