How to increase the internet speed

There are four Internet settings that can be configured, you can get greater throughput (faster Internet downloads) by modifying a few settings. They are the MaxMTU, MaxMSS and DefaultRcvWindow, and DefaultTTL 

Open RegEdit

• Go to HKEY_LOCAL_MACHINE\System\CurrentControlset\ Services\ Class\ net\ 000x
  (where x is your particular network adapter binding.)

• Right click on the right panel.

• Select New\String Value and create the value name IPMTU.

• Double click on it and enter then the number you want. The usual
  change is to 576

• Similarly, you can add IPMSS and give it a value of 536
  (Windows 9X)You can set DefaultRcvWindow, and DefaultTTL by adding
  these string values to HKEY_LOCAL_MACHINE\ System\ CurrentControlset\
  Services\ VXD\ MSTCP

• Set the DefaultRcvWindow to"5840"and the DefaultTTL to "128"

Note: These settings will slow down your network access speed slightly, but you will probably not even see the difference if you are using a network card. If you are using Direct Cable you should see a sight difference.
