Step 1: do *NOT* run Windows on your machine.  NDIS (which is what the 
WinPcap driver uses), and the standard 802.11 drivers on Windows, have 
no mechanism to allow a driver or application to request that it see 
802.11 management frames.

Which NetGear card do you have?  Linux and/or one or more of the 
free-software BSDs might support the card and support putting it into 
monitor mode.  (Note that, in monitor mode, most if not all network 
adapters do *not* support being associated with a network, so you can 
only do passive traffic capture.)
