wow no one knows? well i dont have a laptop, but my friend does and he encountered the same problem. first, you have to make sure that you are not far away from your connection. second, you have to make sure that noting can interfere with the connection. if the problem still persists, try to re-install the wifi connector, because there is a possibility of a bug in the system. also, you can go to the store that sold you the wireless connector and ask if this connector works with your laptop. if this doesnt work, call a repair shop, or someone skilled.
