•

If the WPN802 is configured correctly, check your Internet connection (DSL/Cable modem,

etc.) to make sure that it is working.

•

Try again.

•

When entering configuration settings, be sure to click the

Apply

button before moving to

another menu or tab, or your changes are lost.

•

Click the Refresh or Reload button in the Web browser. The changes may have occurred, but

the Web browser may be caching the old configuration.

Using the Reset Button to Restore Factory Default Settings

The reset button on the rear panel of the WPN802 has two functions:

•

Reboot:

When pressed and released quickly, the WPN802 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. These settings are shown in

“Default Factory Settings”

on page 3-1

.

To clear all data and restore the factory default values:

1.

Power off the WPN802 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 five seconds.

3.

Release the reset button.

The factory default configuration has now been restored, and the WPN802 is ready for use.

This chapter provides an overview of Wireless networking.

Wireless Networking Overview

The WPN802 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, 54, and 108 Mbps.

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

Compatibility Alliance (WECA, see

), 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.
