Here a trick that can help speed up your current modem without shelling out the big bucks.There is a setting located in your windows registry called the Maximum Transfer Unit (MTU). This determines the size of the packets of data sent between your and your server. In Windows 95, this setting is has a value of 1,500 bytes when the actual size of internet packets is 1,000 bytes. This can sometimes slow things down. To remedy the situation, simply follow these steps:
1- In the registry editor (Start > Run > regedit.exe)
2- navigate to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\NetTrans.
3- In the NetTrans folder you should find another folder named "000x" in which x represents a fourth digit.
4- Right-click on the "000x" folder and select New and StringValue. Rename the item that appears in the panel on the right side to MaxMTU, then double-click it to bring up the Edit String box and give it a velue of 1002.
Remember to keep playing with the MaxMTU value until you feel that your internet connection has greatly sped up. Some people report huge speed gains using this tricks, while others hardly notice a difference. In any case, it's definetly worth a try.
