First bring up REGEDIT, type REGEDIT in your run box and hit OK.
Under Registry at the top of the box, click on that, now click on Export Registry File, a box will come up asking where you want to export it to, just put it in your C drive, then name it at the bottem of box, Registry. Click on ALL at the bottom so it copies all of your registry.
Click on save.
Now if you ever get in trouble or want the old regestry back, bring REGEDIT back up and click on Registry and click on import registry file, go to your C drive and click on registry and click open, reboot and your good to go.
Anytime you add a new program, backup again, any program, back it up to the same place as the last one, it will overwrite it. If you do not backup after each new program is instaled you will not have those setting's in regestry if you have to backup for some reason.
Do nothing else in this box as it is the heart of your computer, just what it says above and no more!!!!!!!!!!!!!
Please go to this http://www.dslreports.com/front/drtcp.htmlRL
Download DR. TCP to your desktop
Where it saids adapter settings, select your adapter
Where it says Windows sclaing- yes
Where it says Selective Acks-yes
Path MTU Discovery - yes
Black Hole Detection - No
TTL-64 or 32 (up to you)
Where it says Time Stamping, select No or yes, up to you
The choices I give above will not affect speed
Reboot for changes to take affect
Do not change any numbers in this box unless you know what you are doing.
A blank box only means that the default setting is being used
Set MTU with Dr. TCP, reboot after any changes and click on apply on Dr. TCP

That is EnterNet.
Unlike most other arrangements, with NTS EnterNet you can not use Dr.TCP to tweak the MTU. NTS has decided to limit the MTU (or as they erroneously call it, the 'MaxFrameSize') to a maximum of 1454. Here's what you should do to give you the broadest range for your "possible" MTU.
1. First you have to tweak the registry. Remember NTS has limited the MTU to 1454 while the PPPoE Maximum is 1492. Although this small increase will do you no good if you don't actually have an MTU greater or equal to 1454, it still widens your MTU's upper bound.
Open regedit and drill down to here:
HKEY_LOCAL_MACHINE/System/CurrentControlSet/Services/Class/Net
Find the specific 000n folder (where "n" is a number) that contains the Network Telesystems PPPoE Adapter (NTSP3) adapter. Then drill down further to:
.../000n/Ndi/params/MaxFrameSize
Find this entry: max = "1454".
Double click on max and change this value to 1492. Now reboot
2. Ok, now that you have increased the upper limit for your MTU, it's time to actually increase your MTU. Go to:
Start
Settings
Control Panel
Network
Network Telesystems Enternet PPPoE Adapter (NTSP3)
Click on the Advanced tab
Find "MaxFrameSize" and change it to 1492.
Now reboot.
To be sure that you put the settings in the correct places, go here and down-load some pictures of the registry:
