DunSpeed - Version 1.0 DunSpeed will speed up your internet connection by adjusting the TCP/IP settings and adding extra settings to the Windows Dial-Up Adapter Properties window to 'Fine Tune' the settings, the first of it's kind to do so. Automatic Configuration window lets you choose one of the three most common settings and makes the necessary changes for you. Custom Configuration lets you try an almost unlimited combination. Dun Settings adds a Stay Alive function, Black Hole Detect, Auto Discovery and more. Also has a back up registry function and a link to take a speed test before and after each change. Even if you've tuned your systen before, DunSpeed can improve on it.
