My PC caught lightning while that one was turned off but not disconnected from the phone jack: results of a grilled box and RJ45 socket on the motherboard of my turn ... My PC is not equipped with WiFi more Internet! So to avoid replacing my motherboard I installed the network card on a free PCI slot in my lap, and there internet miracle was back as fast as before. Of course I chose another network port on my box (the other 3 were intact, a stroke of luck). All that to say that this small network card works god of thunder, is recognized immediately in Seven, it comes with a driver CD, but one finds newer online. The price is more than reasonable, delivery is fast, the card comes in a cardboard box with a quick manual and CD.
