Ignore the software and use the built-in wireless utility that comes with Windows to configure your network. There should be a small icon by the clock that looks like a radio antenna with waves, right-click it and select to 'View Available Wireless Networks'. The rest is self-explanatory.
If the Windows utility states that it is not managing your wireless networks, you'll need to disable the Zonet utility first. If you need help with that, let me know.
Good Luck!
