No modifications to your hardware are made and all adjustments and settings are done in an easy to use interface that a child could use. Most 'other' modem enhancers promise that they work while you notice no difference at all in internet speed.
NetScream on the other hand has been tried and tested and proven to work. Whether you use a 14.4/28.8/33.6/56k modem, cable modem, or DSL modem, NetScream will boost your internet connection speed. NetScream modifies your modem settings so those annoying disconnections and hang-up's will happen less often.
