HI Asus Eee

you may have another wireless connection other than your own set as automatic, or more than one connection in your settings of the same name, so right click on your network icon in your task bar or in network connections in device manager and select view all wireless connections, click on it and when all the connections show, highlght, delete all of them, then close the window.

Your notebook should now indicate that it found new wireless connections, click on the popup and select your connection name and click connect, at this point you will be asked to enter the passkey if you have security enabled.
