Hi eaglehdr,
This system is not tested with Windows 7 Operating system; hence the drivers are not available. However you may try installing the Vista 32 bit wireless driver in the compatibility mode. This may or may not work.
Download the file and extract it on the desktop in a folder. Look for setup file in the extracted folder. Right click ‘.exe’ file and click ‘Properties’. Click “install in compatibility mode’. Click on Application and select ‘Troubleshoot Compatibility’. Next, click on ‘Troubleshoot Program’. Click on Program worked in earlier versions of Windows. Click on ‘Start the Program’. Do not hit ‘Next’ until the installation completes. Once the installation completes, click on ‘Next’.
Please let me know if this helps.
