Sorry guys but i just wasn't getting any change. I reverted back to the default settings and was gettin the same connection speed without the tweaks. So I am going to start over. I have installed the SG Tweak and Web Tweak.
AMD 1.01GHZ
WIN XP Prof
256 MB RAM
Rogers@home
Capped speed 3 Mbps Up
400 Kbps upstream
I haven't entered any RWIN values yet just the sgTweaks and my speed test rates me at 39 times faster than 56K.
Is it really just trial an error with the RWIN values? What should I start at and how far should I go?
Browser/OS = Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; MSOCD; AtHome021SI)
TCP options string = 020405b40103030201010402
MTU = 1500
MTU is fully optimized for broadband.
MSS = 1460
Maximum useful data in each packet = 1460, which is equal to MSS.
Default Receive Window (RWIN) = 256960
RWIN Scaling (RFC1323) = 2 bits
Unscaled Receive Window = 64240
RWIN is a multiple of MSS
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

Crispy, please tell me what this is and what you are doing, 513920 is way to small for a 1 GiG puter and none of the other numbers are fast or multiples, please check analyzer here at Speedguide before you give out these numbers.
DEVX2K, like he said above, need to know if Cablenut adjuster is installed

Bring up Cablenuts adjuster inside Cablenut on desktop the numbers below go in 3 places in W2k and XP, they are: DefaultReceiveWindow, TcpWindowSize, GlobalMaxTcpWindowSize, take out number that is in there and put in one of these, 1 at a time, try: 51100, 522680, 531440 or 554800
You do not have to show me but check analyzer here at SG to make sure RWIN is in, you will see number right after (RWIN) on analyzer
At bottom click save to registry, and REBOOT each time you change value in adjuster or it will not work. Click on tools at top of IE, internet options, delete files and offline files (This is safe, temp files) and click on clear history after EVERY test . Quick speed test here
Speedtest may open another browser, so check taskbar and close other, no other programs should be running, No AIM, ICQ, Virus scanner, Firewall, nothing
Once you find fast number for you, you want to save it, on file at top of adjuster click on that, save custom settings, put RWIN size in as name and click on save, now if you ever want these settins back, click on file, open custom settings file, and click on RWIN number, then click on save to registry at bottom, and REBOOT, your done. How to do real dowwnload test on help thread below in signature. This is all I recommend, if anyone else jumps in with something else, good luck, but it did not come from me
Also add NIC Buffer setting's in adjuster: These setting's are for people with Speedguide's speed patch installed.

Tweaks for Windows XP
1.) Turn off System restore and auto updates. If you keep registry backed up you do not need System Restore.
2.) Use SG's System ini tweak set at 7168, type sysedit in run box, Close out of all boxes except System Ini, put it in 386th Enh, thats where it goes , see if it helps you are not, if you don't have alot of RAM it might not.
3.) Go to control panel, system, advanced tab at top,performance, settings, click on best performance,then advanced tab at top, background services, then programs
4.) Disable IDE Port Scanning on empty ports and save bootup time.
Go to System Properties by right-clicking on My Computer or via the Control Panel.
Select the Hardware tab.
Look at the Device Manager section and click on the Device Manager button.
This brings up the Device Manager screen.
Open up the IDE ATA/ATAPI controllers device branch. Then you will see a list of all the IDE controllers
and channels in your system.
Now, select any one of the IDE channels, right click and choose Properties. Or just double click on the
IDE channel.
Now, select the Advanced Settings tab to get the screen below. As you can see below,
the second port (Device 1) on the Primary IDE Channel does not any IDE device attached to it.
Thus, the Device Type is labeled as Auto Detection. In contrast, the first port has a device attached. That's why the Device Type is grayed out.
To disable IDE device scanning for the second port, click on Auto Detection and you will see
two choices on the list. Select None.
Click OK and reboot. Windows 2000 will now refrain from scanning that IDE port at start up and
should load a little faster
5.) Use Win 2000- patches for XP
6.) Yes Cablenuts adjuster works with XP
7.) This is the neatest, do it and come back to forum,
Click Start, click Control Panel, and then click Appearance and Themes.
Click the Display icon, click the Appearance tab, and then click Effects.
Click the Use the following method to smooth edges of screen fonts check box to select it, and select ClearType from the list.
Click OK, and then click OK again.

Here's a great tip to speed up your browsing of Windows 2000 machines. Its actually a fix to a bug that by default of a normal Windows 2000 setup that scans shared files for Scheduled Tasks. And its turns out that you can experience a delay as long as 30 seconds when you try to view shared files across a network from as Windows 2000 is using the extra time to search the remote computer. Note that though the fix is originally intended for only those affected, Windows 2000 users will experience that actual browsing speed of both the Internet & Windows Explorers improving significantly after applying it since it doesnt search for the Scheduled Tasks anymore. Here's how :
9.) This make broswing alot faster, but if you use scheduled tasks, don't do this,
Open up the Registry and go to :
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version/Explorer/RemoteComputer/NameSpace
Under that branch, select the key :
{D6277990-4C6A-11CF-8D87-00AA0060F5BF}
and delete it.
10.) Auto Logon XP
real easy and straight forward.
1. click on "Start" - then click on "Run" - type "control userpasswords2"
2. click OK
3. On the Users tab, clear the "Users must enter a user name and password to
use this computer" check box.
4. A dialog will appear that asks you what user name and password should be used to logon automatically.
Your all set.
11.) One of the most full featured Windows XP configuration tools available is hidden right there in your system, but most people don't even know it exists. It's called the Local Group Policy Editor, or gpedit for short. To invoke this editor, select Start and then Run, then type the following:
gpedit.msc
12.) You can easily create a bootable floppy disk by following these steps:
Place a blank disk in the floppy disk drive.
Click Start, and then click My Computer. Or My Computer Icon on desktop
Right–click the floppy disk drive, and then click Format on the shortcut menu.
Click Create an MS–DOS startup disk, and then click Start.
Now you’re on your way to a bootable startup disk.

14.) Click on tools at top of IE, internet options, settings, click on every visit to page, helps on forums alot
15.) Everytime (Not once while testing, EVERYTIME you test) you must clear temp files, offline files and history files, directions on help thread in signature
16.) More comfortable performing a task with the familiar Windows Classic user interface? You can quickly switch the user interface to the familiar Windows Classic appearance on your computer if it helps you remember a task in your operating system or program. You can go back to the original Windows look with a couple clicks.
Right-click on your desktop, and then click Properties.
Click the Appearance tab.
On the Windows and Buttons menu, select Windows Classic. Click OK.

Auto Logon to a Windows NT/2000 Machine (Windows NT/2000) Updated Popular
Category: Enhancements > Windows NT, 2000 & XP
Windows NT/2000 includes a feature that allows you to automatically logon to the machine and network, bypassing the Winlogon dialog box.
To enable this function you need to add several new values to the key below.
Add a new string value named 'DefaultUserName' and set it to the username you wish to automatically logon as.
Add a new string value named 'DefaultPassword' and set this to the password for the user entered above.
Add a new string value named 'DefaultDomainName' and set this to the domain of the user. Ignore this value if the NT box is not participating in NT Domain security.
Add a new string value named 'AutoAdminLogon' and set it to either '1' to enable auto logon or '0' to disable it.
For Windows 2000 the additional ForceAutoLogon setting must be enabled to stop the tweak from resetting on reboot.
Exit and restart, Windows should not ask for a password and automatically show the desktop of the user.

DEVX2K, like he said above, need to know if Cablenut adjuster is installed
551600, 513920(My personal use for my Tbird 1.2), 524140, and 559180 are all Multiple Rwins.. I don't know how you do at math, but according to my calculator, they are all Multiples..

Crispy, if you look real close their are 2 statements their, RWIN recomemdation which has NIC buffer tweaks and XP tweaks which also include NIC Buffer tweaks, did you think he put them in twice? As far as RWIN numbers, you or your calc are on crack, check analyzer!!!!!!!!!!!!!!!!!

Ok, but explain why you put 524140 and the analyser reports 524136 ???? May be i missed something, i dont understand that...Originally posted by Lobo
Crispy, did you go to school, did you take math, I put 524140 in and:
Default Receive Window (RWIN) = 524136
RWIN Scaling (RFC1323) = 3 bits
Unscaled Receive Window = 65517
For optimum performance, consider changing RWIN to a multiple of MSS.
Other values for RWIN that might work well with your current MTU/MSS:
513920 (MSS x 44 * scale factor of 8)
256960 (MSS x 44 * scale factor of 4)
128480 (MSS x 44 * scale factor of 2)
64240 (MSS x 44)

Front page this site FAQ's about analyzer
11. I set my RWIN to N, but the Analyzer shows something slightly different. What gives?
While you can enter any RWIN value in the registry, the TCP stack will only accept some values. The value you see on the page is the best compromise between what you entered and what the stack is willing to accept. TCP headers only contain an unscaled RWIN value lower than 65536 and a scale, or rather shift factor used for larger RWINs. Valid RWIN values must be divisible by 2^shift factor. That can create slight differences however the value that the analyzer reads is what every other server on the net will get as well.
