MEDIALINK Wireless Adapter MWN-CB54G can be configured by MEDIALINK Wireless Client
Utility (MWCU). This chapter describes how to configure your MEDIALINK Wireless Adapter for
wireless connectivity on your Wireless Local Area Network (WLAN) and use the data security
encryption features.
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 MWCU will run. You can also run the utility by clicking the
