My built-in wireless card does not support the N-standard, so I have chosen this. Drivers were just installed Windows, Linux I have not tried it yet. Very good quality (better coverage than Erstausrüsterkarte in Aspire 5520) reception quality is also increased slightly. It is important that the data transmission is faulty, if not both antennas are also connected, but what stands out more or less in all the wireless cards.
