Hey.
I searched around on my PC and I found this tool.
I use it everytime when I format my harddrive or when Tuneup changes something in my Internet settings.
Sometimes it seems like I got a DSL 1000 instead of 16k and then, I start this program and can see:
WOW, Something is different here o_O
So I want to post it here..
The program is called TCPOptimizer and made by speedguide.inc

First of all you download the program and safe it for example on the desktop.
Then doubleclick the .exe.
Now you should see this screen:
You see the numbers ? I will explain the most important functions.
1) Here you can see which settings for Internet you got. [ When you click on the bottom on Custom settings you can change whatevery you want!
2) Here you should choose your Ethernet controller -> This one will be changed
3) " Advanced Settings "
Here you can go for advanced things like maximum connections.
NOTICE: You have to choose " Custom Settings " on the bottom to change something !
4) " Largest MTU "
Here you can make something like a " Speedtest ".
5) " BDP "
[quote] The SG RWIN/BDP Calculator is a tool provided for quick calculation of approximate RWIN (TCP Window) values using the BDP (Bandwidth*Delay Product).

I think this says everything so I can go on..
6) " Latency "
You can choose between some pages to test your Ping / Latency.
There are 5 Pages to choose but you can change them if you want.
7) " Registry "
In this section you see your registry and now you can easily change the settings to whatevery you want without looking up!
TAKE CARE OF WHAT YOU CHANGE!!!!
8) " File "
You changed something in your registry and now your Internet is fucked up ? - I was known what you'll make something wrong.. But what a luck that this tool is able to make backups!
So make a backup before you change something!
You have to click on "file" ->"Restore backed up Settings " to reload the "old" settings..
If you got any questions feel free to post them in this Thread or to PM me.
I hope you enjoy this tool.
