Hello, i have This wireless adapter: http://ecx.images-amazon.com/images/I/3108l3ay9SL._SL500_AA280_.jpg and for the past while the Activity light has been blinking non-stop Very fast. And when it is plugged in it seems like it is using too much bandwidth because the other computers in the house start to lag when it is on. When it used to do this a few months ago all i had to do is restart my computer and it worked, but i tried that and it didn't work. Any help?
