I've bought the stick because I was on the terrace where I had most seats a weak to medium reception with my instruments. The transfer of images or larger documents always took an eternity - these are on a Buffalo NAS on your home network (100 Mbit connection to the access point). Compared to the internal wireless card (Sparks after N standard) in the notebook achieved the TP-Link is almost twice as high speed (6.5 to 7.5 MB / sec - megabytes, not megabits!) To Huawei HG556a Vodafone router / access point. That's a very decent value considering the distance and the maximum bandwidth that is available to me!
What can be complicated to install the drivers personally I do not understand! The stick could be no problems with the supplied driver CD under Windows XP, Windows Vista (32 and 64 bit) and install Windows 7 (including 32 and 64 bit).
