I am extremely satisfied with this card WiFi N. Both antennas are still too small and the possibility of directing does not change much the quality of signal reception. This card sinstalle easily under windows xp and windows 7 is recognized immediately and does not require to install some drivers whatsoever. It is compatible with ultra box, I tried three different brands or ISP. I often advise as to not install the software on the CD because most of the time are noodle jokes and serve mainly to advertise more to serve the user
