Changing the MaxMTU for faster Downloads

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

1.Open RegEdit
2.Go to
HKEY_LOCAL_MACHINESystemCurrentControlset Services Class net 000x
(where x is your particular network adapter binding.)
3.Right click on the right panel
4.Select NewString Value and create the value name IPMTU
5.Double click on it and enter then the number you want. The usual change is to 576
6.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.
