If you have a recent Mac.....
Open up Macintosh HD > Applications > Utilities > AirPort Utility
Click on the AirPort icon, then click Edit in the smaller window that appears
Click the Base Station menu up at the top of the screen
There is a setting for Add WPS Printer there, but it should work for vitually any WPS device
Choose the First Attempt option as a substiture for a button, which the AirPort does not have
If all else fails, then you will need to use the manual connection method suggeted by Netgear, not the WPS method.
