Wireless WLAN Transmitter for Desktop Computer? [closed]

This should work fine. When you insert it into your computer, the device will become your wlan card and connect to your wifi at your house :)

Actually, what you've bought is itself a wireless USB network card, so it will work without much hassle. Depending on the internal electronics of the card, it could work just by plugging into a USB port and waiting a few seconds for the Windows driver autoinstall, but if Windows can't find the drivers yo will need to install them manually, ususally using a CD included in the box of the WiFi card.

Now, if you can avoid WiFi as possible and stick to cable, this will give you a better performance, but if you will use your PC only to surf the WEB or to stream low bitrate video (As the one on Youtube) you will not see any performance penalties, unless your local WiFi medium is very populated from neighbours WiFi, I think you should consider this.
