Description of Settings

The following are explanations of each adapter setting in the Configuration menu.
Mode: The Mode setting determines the architecture of your wireless LAN. Choose Ad­Hoc or Infrastructure Mode, depending on your network type. A brief explanation of each
mode follows.

• Ad-Hoc: This mode is used for a simple peer-to-peer network. This type of network

only allows the sharing of local resources between wireless clients without a wireless
Access Point.

• Infrastructure: This mode allows a wireless LAN to be integrated into an existing

wired network through an Access Point. Infrastructure type networks also permit
roaming between Access Points while maintaining the connection to all network
resources. Infrastructure mode provides additional features, such as W EP security,

power saving, and extended range.
SSID (Service Set Identifier): SSID is the unique name that is shared among all clients
and Access Points in a wireless network. The SSID must be identical for all clients or
Access Points participating in the same network. T he SSID is case sensitive and must
not exceed 30 characters.
Tx Rate (transmit rate): Tx Rate selects the allowabl e transfer rates of the w ireless cli ent.
To optimize performance and range, the Tx Rate should be set to Fully Automatic. This
will automatically adjust the transfer speed for the best perf ormance and longest range.

WEP (Wired Equivalent Privacy): WEP is an encryption scheme that is used to protect
your wireless data communications. WEP uses a combination of 64-bit keys or 128-bit
keys to provide access control to your network and encryption security for every data
transmission. To decode a data transmission, each wireless client on the network must
use an identical 64-bit or 128-bit key.

The 64-bit or 128-bit WEP keys can be generated from a user-defined pass-phrase. The
pass-phrase is any text string with a maximum of 32 characters. To generate encryption
keys for each client that is communicating in the wireless network, perform the following
steps:

1. Enter the same case-sensitive text in the Pa ssphrase entry field for each client.

2. Click Generate to create the encryption keys. The passphrase generates four unique
keys.

3. Select the same default key in the drop-down box for each client. This is the key the
clients will use to encrypt data.

4. Click Write to store the information in the registry.

5. Select the Configuration tab and choose Mandatory in the WEP option.

6. Click Apply Changes and then click OK.

Appendix A Troubleshooting

My computer does not recognize the Wireless USB adapter

Possible Solution:
The USB Wireless LAN adapter not fully inserted into the USB port.

The Wireless LAN USB adapter does not work properly.

Possible Solution:
Check the USB adapter services and be certain the Wireless LAN USB adapter is not in

use before removing it. The laptop will lock up if the USB W ireless LAN adapter is in
use and is removed. Reinstall the Wireless LAN USB adapter. You will hear a beep if the
card is properly inserted into the USB port.
The power LED indicator will be solidly lighted or flashing if the cable is properly
connected. For Windows 2000, NT, and ME, ensure that a USB adapter service driver is
installed in your computer. Perform the following steps to check for the service driver:

Click Control Panel and then Wireless LAN USB adapter Check to see if it has the
Wireless LAN USB adapter in one of the USB port. If you see a yellow question mark,
there are conflicting resources or the driver is not correctly installed

.

My computer does not recognize the USB wireless LAN adapter after I changed the
settings.

Possible Solution:
Ensure that the LAN Configuration utility is installed . Ensure that you are contacting the

correct USB wireless LAN adapter and using the correct MAC address. Ensure that the
correct pass-phrase and e ncryption option are being used. If you changed the settings in
the configuration of the USB wireless LAN adapter, you must also change the settings of
USB wireless LAN adapter attached to this network. The settings of the LAN
configuration must match the new settings of the USB wireless LAN adapter

My computer is not acknowledging my USB wireless LAN adapter.

Possible Solution:
Make sure that the USB wireless LAN adapter is plugged into USB port and is properly
installed. It may be necessary to remove the associated programs, uninstall the Access
Point, and repeat the installation procedure. Unplug the USB wireless LAN adapter to
clear the information and then plug the Access Point back in.
