Installation is very simple on my Windows 7, just read the instructions and follow the instructions and choose the drivers ... Sold with a mounting bracket (vacuum or forceps) handy with the pliers by putting it behind the pc desktop screen. Before I used a small key usb wifi and I had a small reception poor due to the thickness of my walls with connection losses was miserable, now with Alfa Network I capture all my wifi available area is still impressive range ... and it provides for network games is not perfect, frankly I recommend this product
