My apologies, I for some reason thinking it had on board wireless...let me get home from work and look at it again.
No problem. That's the fun with tech support: the details matter. While you are at it, please verify if it really is Broadcom or if it is Realtek as the MB specifications list. Motherboards do sometimes have multiple generations and change components. Again, your Windows device manager software should be able to tell you without opening up the box.
