The WGT624v3 is not a network adapter. It's a 4-port combo wireless router and it does not require a driver. Please read the instructions on how to use it. If you don't have the instructions, please visit the Netgear website and download one.

Or state what your problem is and perhaps we can solve it for you. BTW. it has nothing related to SCSI.
