Transmit Rate 

The IEEE802.11g Cardbus Wireless LAN Card provides various data rate options for you to 
select. Data rates options include 

1Mbps

, 

2 Mbps, 5.5 Mbps

,

 11Mbps, 6Mbps, 9Mbps, 12 

Mbps, 18Mbps, 24Mbps, 36Mbps, 48Mbps, 54Mbps 

and, 

Fully Auto

. In most networking 

scenarios, you will see that the factory-set default “

Fully Automatic

” will prove the most 

efficient. This setting will allow your IEEE802.11g Cardbus Wireless LAN Card to operate at 
the maximum data rate. When the communications quality drops below a certain level, the PCI 
Card will automatically switch to a lower data rate. Transmission at lower data speeds are 
usually more reliable. However, when the communications quality improves again, the 
IEEE802.11g Cardbus Wireless LAN Card will gradually increase the data rate again, until it 
has reached the highest available transmit rate. 
 

WEP

To prevent unauthorized wireless stations from accessing data transmitted over the network, the 
WLAN Utility offers highly secure data encryption, known as WEP, making your data 
transmission over air more secure. To activate the WEP Encryption, check the 

WEP Enabled

check box. An Encryption window will then appear. The instructions are as follows: 

¾

Pull down the 

Encryption (WEP)

 menu and select either 

64bit

 or 

128bit 

encryption 

method. 

¾

Specify the encryption keys. There are two methods to set the WEP keys, as described 
below: 

Create Encryption Keys by Using a Passphrase

To create encryption keys by using a passphrase, click the 

Create Key with Passphrase

check box and type a character string in the 

Passphrase

 field. As you type, the utility uses 

an algorithm to generate 4 keys automatically. Select either the 

64bit 

or 

128bit

 encryption 

first, and type a string in the 

Create Key with Passphrase

 field. Select one key from the 4 

WEP keys and click 

OK

. Then click the 

Apply

 button on the 

Configuration

 tab to make the 

setting take effect. 

Warning: 

When 

Create Key with Passphrase

 is enabled, the wireless device’s Key with 

PassPhrase must match the Key with PassPharse used by the access point with which 
wireless device is planning to communicate.
