Limiting the wireless transmit rate - Limiting the wireless transmit rate can help
improve the maximum wireless range, and connection stability. Most wireless cards have the
ability to limit the transmission rate. To change this property, click Start, Control Panel,
Network Connections, then double-click your card's connection. In the Properties dialog,
select the Configure button on the General tab (Windows 98 users will have to select the
Wireless Card in the list box and then click Properties), then choose the Advanced tab and
select the rate property. Wireless client cards are usually set to automatically adjust the
wireless transmit rate for you, but doing so can cause periodic disconnects when the wireless
signal is too weak; as a rule, slower transmission rates are more stable. Experiment with
different connection rates until you find the best one for your environment; note that all
available transmission rates should be acceptable for browsing the Internet. For more
assistance, see your wireless card's literature.
Why are there two wireless utilities in your system tray?
Which one should you use?
There are several features and advantages to using the WNU over the Windows XP Wireless
Zero Configuration utility. We offer a site survey, detailed link information, and adapter
diagnosis.
It’s essential to know which utility is managing your adapter. We recommend using the WNU.
To use the WNU:
1 Right-click on the network status icon in the system tray and select View Available
Wireless Networks.
2 Click the Advanced button in the lower left-hand corner of the Available Wireless
Networks window.
3 From the Advanced tab, uncheck Use Windows to configure my wireless
network. After the box is unchecked, click OK to close the window.
You are now using the WNU to configure the card.
The card does not work or the connection is unstable
when the computer has a second built-in wireless network
card (such as a mini PCI or Intel® Centrino™)
This condition occurs if your computer has a built-in wireless card while your Wireless Card is
also active. This happens because Windows must now handle two active wireless
connections.
You need to disable the built-in wireless card from your computer under Network Adapters
in the Device Manager.
