I cannot connect to the WG102 to configure it.

Check these items:

•

The WG102 is properly installed, LAN connections are OK, and it is powered on. Check that

the LAN port LED is on (amber indicating a 10 Mbps Ethernet connection or green indicating

a 100 Mbps Ethernet connection) to verify that the Ethernet connection is OK.

•

The default configuration of the WG102 is for a static IP address of 192.168.0.229 and a Mask

of 255.255.255.0 with DHCP disabled. Make sure your network configuration settings are

correct.

•

If you are using the NetBIOS name of the WG102 to connect, ensure that your computer and

the WG102 are on the same network segment or that there is a WINS server on your network.

•

If your computer is set to “Obtain an IP Address automatically” (DHCP client), restart it.

•

If your computer uses a Fixed (Static) IP address, ensure that it is using an IP Address in the

range of the WG102. The WG102 default IP Address is 192.168.0.229 and the default Subnet

Mask is 255.255.255.0.

When I enter a URL or IP address I get a timeout error.

A number of things could be causing this. Try the following troubleshooting steps.

•

Check whether other PCs work. If they do, ensure that your PCs TCP/IP settings are correct. If

using a Fixed (Static) IP Address, check the Subnet Mask, Default Gateway, DNS, and IP

Addresses.

•

If the PCs are configured correctly, but still not working, ensure that the WG102 is connected

and turned on. Connect to it and check its settings. If you cannot connect to it, check the LAN

and power connections.

•

If the WG102 is configured correctly, check your Internet connection (DSL/Cable modem

etc.) to make sure that it is working correctly.

•

Try again.

Using the Reset Button to Restore Factory Default Settings

The Reset button (see

“WG102 rear panel” on page 2-7

) has two functions:

•

Reboot.

When pressed and released quickly, the WG102 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 WG102 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 WG102 is ready for use.

Wireless Networking Basics

This chapter provides an overview of Wireless networking.

Wireless Networking Overview

The WG102 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

), 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.
