Transmit Rate
The 802.11g Wireless LAN PCI 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 802.11g Wireless LAN PCI 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 802.11g Wireless LAN PCI 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:
$ Pull down the Encryption (WEP) menu and select either 64bit or 128bit encryption
method.
$ 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.
