Query: Worst wireless adapter ever

This wireless adapter is a waste of money. It is VERY hard to install it, if not almost impossible if you haven't the driver CD (the drivers from the internet are even worse). But once you have installed it you will soon find out that the connection is very unstable... well, my body is able to establish a better connection than this thing. Don't buy it. It is worthless.
