    Do this first:
    1. Go to http://forums.speedguide.net/optd.shtml and click on check connection.
    2. Copy all this by highlighting everything in box with mouse
    (you may have to make box smaller. To copy contents of box, highlight, then hit Ctrl & c, on your keyboard, when you return to Speedguide in reply box, with cursor blinking, hit Ctrl & v, this will copy contents in box so I may look at it. Thank you.

    OK, First this is very important:
    This is a must unless you the future in want to format because you did not do it, please do this. 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 plus date. 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!!!!!!!!!!!!!
    First go to www.cablenut.com , click on software at top of page
    Download 4.0
    His patch will uninstall previous patchs
    Install 4.0

    Then on desktop click on cablenut 4.0
    Click on ccs files
    then click on cable
    Select either fast cable 9x
    this will enter settings
    click on save to registry at bottom, reboot or it will not work.
    (NOTE) If you are running WIN 98 or SE, you need to download and install Vtcp386 for patch for 4.0 to work. If you wish timestamps turned on in adjuster where it says Tcp1323Opts set this to 3.
    If you decide to remove Cablenut's patch, use uninstaller in Cablenut 4.0 folder on desktop. This will take you back to Windows default. YOU need Vtcp 386 patch

    You will not be able to do any speed testing at this hour, but after you install patchs do test above and post it here so I know you have it in right, you might want to print this:
    How do do speed test
    1. The best time is early in the morning (3 AM - 6 AM)
    2. Make sure defrag has been run so no files are fragmented
    3. Delete Temp internet files, not while testing, but after each test. IE browser, click tools, internet options, click on delete files and no this will not harm system, just get rid of temp files
    4. Go to a fast server such as www.happypuppy.com and click on 10 demos, select a LARGE file to download (not all of it of download, just most of it, before you click cancel) this will show you how fast you are downloading, it's not going to be quick except except early in morning when not many people on net. I recommend you go to www.analogX.com and download Net State live, run this while downloading as it will give you avg of your download speed.
    5. Probably the most important, nothing can be running during test, no firewalls, no virus stuff, no ICQ, no AIM (some of you may have to go into BIOS to disable virus scanner, nothing running except Net Stat live
    Scheduled tasks will run disk defrag, 98 & SE in Taskbar, WIN ME in control panel


    Or if you wish you may go to www.testmyspeed.com and do one of the online tests, these vary to much for me but you may like them. Another one is at www.dslreports.com/tools

    SpeedGuide.net TCP/IP Analyzer
    TCP properties for IP =
    Note: Read the FAQ if the above is not your IP address.

    TCP options string = 020405b401010402

    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) = 8760
    RWIN Scaling (RFC1323) = 0 bits

    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)
    256960 (MSS x 44 * scale factor of 4)

    Your RcvWindow limits you to: 140.16 kbps (17.52 KBytes/s) @ 500ms
    Consider increasing your RWIN value to optimize TCP/IP for broadband.

    Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
    For optimum performance, consider changing RWIN to a multiple of MSS.

    did the download but it will only tell me it is not a windows help file when i try to open it.
    does my settings appear they could use some more tuning? i am new to tweaking so any help or recommendations you have are greatly appreciated.

    MTU = 1500
    MTU is fully optimized for broadband.

    MSS = 1460
    Maximum useful data in each packet = 1448, which is less than MSS because of Timestamps, or other TCP/IP options used.

    Default Receive Window (RWIN) = 204400
    RWIN Scaling (RFC1323) = 2 bits
    Unscaled Receive Window = 51100

    TTL value is ok.

    Timestamps (RFC1323) = ON

    lobo,here is what i get after installing the tweaks you suggested.

    lobo im still getting crappy download speeds...maybe I did the vtcp wrong and need to d/l the vtcp.386 from speedguide.net instead. anyway if you got suggestions then send me via email or lets hook up on icq.
