I installed this "booster" antenna on my wireless Access Point to see if it would help the connection speed with my laptop, which is about 150' away from the AP. Before installing the new antenna on the AP, I had 2 bars with the factory installed 2dbi antenna. After I installed the new antenna, I now have 2 to 3 bars on my laptop, but there isn't any noticeable connection speed difference...it still connects at 5 mbps to 11 mbps. As a result, I still cannot stream any videos. It was wasting of money for me. Based on the reviews by others, it may be a better investment to buy a high power USB wireless adapter, like GSKY High Power 500mW 27dBm 802.11b/g USB Wireless WiFi LAN Adapter With High Gain 7dBi Panel Antenna. That will be my next purchase.
