These will work well if you dont use a cable box with your TV. It will boost the signal and clear up your pic a little. 95% of the time, this wont magically make your internet faster or improve your digital picture.

i ordered one.

There's no way to "boost" the speed of your internet. Those parameters are set with your internet provider. There are more factors that are out of the customer's control that affect speed.
