I have two of these sticks ordered two slightly older XP computers equipped with WiFi. The installation was thinking just with the enclosed CD - but you should install only the Driver and not the associated software (found this a bit too confusing and complicated). The settings for the network or the different wireless networks can be regulated through the Windows custom finish. The connection to an existing network worked immediately and the connection is stable. Used the stick with a 300Mbit router also from TP-Link and although the computer is about 15m away from the router is the reception at 4 by 5 strokes. The supplied bracket is park table and it looks even chic - that little detail with the stick cap holder I also solved very successfully. So you no longer lose the cap at least :)
You get here for little money a really good stick - great welcome, stable connection, easy handling.
