Chapter 3 Configuration for Windows XP
TP-LINK TL-WN821N can be configured by TL-WN821N Wireless Utility (TWCU) in Windows
XP & 2000. This chapter describes how to configure your Adapter for wireless connectivity on
your Wireless Local Area Network (WLAN) and use the data security encryption features.
The configuration of the adapter in Windows XP is similar with that of Windows 2000. This User
Guide takes Windows XP for example.
For the configuration in Windows Vista, please refer to Chapter 4.
After Installing the Adapter, the Adapter’s tray icon will appear in your system tray. It
appears at the bottom of the screen, and shows the signal strength using color and the received
signal strength indication (RSSI).
If the icon is gray, there is no connection.
If the icon is red, there is poor signal strength and the RSSI is less than 5dB.
If the icon is yellow, there is poor signal strength and the RSSI is between 5dB and 10dB.
If the icon is green, there is good signal strength and the RSSI is between 10dB and 20dB.
If the icon is green, there is excellent signal strength and the RSSI is more than 20dB.
Double-click the icon and the TWCU will run. You can also run the utility by clicking the Start→
Program→ TP-LINK→

TWCU provides some integrated and easy tools to:
