WTH??

Charging for software to use the machine you bought and paid for

This leaves a bad taste in my mouth

Is this what I need?

Will it even work with a 2006 router?

I saw something about an overpriced converter but I have a real Desktop PC so I assume I can drop a PCI card to do the same thing for a fraction of the price
