Netgear WN111v2 Mac Installation Software???

I have a Netgear WN111v2 USB Wireless adapter that I want to use to connect to a Netgear Router.

I thought since I was replacing my old Netgear Wireless adapter (it got broke) that I wouldn't need the installation software (it only comes with Windows installation software).

My System Pref->Network doesn't recognize the adapter when plugged in.

So, is there a Mac version for this adapter or am I going to have to return it to the store?
