here is a trick to increase the internet speed and downloading speed over dial-up modem...

In the registry editor (Start -> Run -> type > regedit.exe > press Enter), navigate to


HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\tcpip


In the Tcpip folder you should find another folder named "parameters" in which there will be a folder named "interfaces".

Scroll down that folder and u will find the adapter id {3899B179-7BA7-4CEF-A165-9A4C092BE67B} for modem. Select the adapter ID and in the left hand Pane make a new DWORD value and name it as MTU and set the size of the MTU to 3000 in decimal and restart ur computer.

Remember to keep playing with the MaxMTU value until you feel that your internet connection has greatly speed up. It reports huge speed gains using this tricks, while others hardly notice a difference. In any case, it's definetly worth a try.
