You really just playing with MTU settings and so....I know I can get you a program that will "assist" you in chaging a WHOLE lot for ANY win32 OS. But....if used wrong you can kill things....this can even tweak external programs and hardware settings too.....Also has settings for internet stuff.
Yea, that things not reliable. I just did a speed test and it says I go at about 4545.5 K bytes/sec. I just aplied the regestry patches for my cable modem, but I don't belive for a second they made my connection THAT fast.
