We've tried it out at several of our customers and our own connection and NAS and it is AB-SO-LU-TE-LY useless ...
Sometimes you get a connection, sometimes not.
Speedwise, your faster off jumping in your car and driving an hour to get 100MB across ...
I don't understand why NetGear even wants to put this out there ... it's simply said crapware on a Mac.
So I just wanted to share this with you to stop you from wasting days trying to get this to work at a reasonable speed.
