    PLEASE HELP! VISTA and 10meg service

    Currently I am only getting about 8.5 megabit on the dl. Can you guys give me a hint as to what I should do to get my dl closer to 10meg? I am a long time user of this forum. Do you guys still use cablenut to edit settings? Here are mine:

    TCP options string = 020405b40303080101010402

    MTU = 1500
    MTU is fully optimized for broadband.

    MSS = 1460
    Maximum useful data in each packet = 1460, which equals MSS.

    Default TCP Receive Window (RWIN) = 65536
    RWIN Scaling (RFC1323) = 8 bits (scale factor of 16)
    Unscaled TCP Receive Window = 256

    RWIN is not fully optimized (even though it is a comparatively large number). The unscaled RWIN value is lower than it should be. Also, RWIN being close to and above 65535 does not justify the header overhead of enabling TCP 1323 Options. You might want to use one of the recommended RWIN values below.

    For optimum performance, consider changing RWIN to a multiple of MSS.
    Other RWIN values 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)

    bandwidth * delay product (Note this is not a speed test):

    Your TCP Window limits you to: 2621.44 kbps (327.68 KBytes/s) @ 200ms
    Your TCP Window limits you to: 1048.576 kbps (131.072 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON

    Time to live left = 118 hops
    TTL value is ok.

    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON

    IP type of service field (RFC1349) = 00000000 (0)

    My pc is Vista Beta2 and I am using 1.5 gigs of ram with a Dual Core X2 4800 Amd cpu. thanks!

    No, Philip wrote his own teaking program..the Speedguide TCP Optimizer. His tweaking utilities is what brought this site up a long time ago. Cablenut is someone elses program...available at their website.

    I'm not sure if current version will affect Vista or not...as it's still in Beta..and over a year away from being finalized..at least a year away.

    For that speed I'd try 513920 or 256960 for your RWIN...try each. MTU set at 1500. Speedguide TCP Optimizer.

    Ok so I am back on XP home sp2. I have the tcp optimizer loaded. Now how to I edit this stuff? Here are my current settings:

    TCP options string = 020405b401010402

    MTU = 1500
    MTU is fully optimized for broadband.

    MSS = 1460
    Maximum useful data in each packet = 1460, which equals MSS.

    Default TCP Receive Window (RWIN) = 65535
    RWIN Scaling (RFC1323) = 0 bits
    Unscaled TCP Receive Window = 65535

    Note: TCP 1323 Options need to be enabled for RWIN over 2^16 (65535). Windows 9x might also need the MS Vtcp386 fix.
    For optimum performance, consider changing RWIN to a multiple of MSS.
    Other RWIN values 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)

    bandwidth * delay product (Note this is not a speed test):

    Your TCP Window limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
    Your TCP Window limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON

    Time to live left = 118 hops
    TTL value is ok.

    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON

    IP type of service field (RFC1349) = 00000000 (0)




    What should I do for my 10/1 plan? Thanks.

    Try thease in the sg optmizer below me to download and install

    General Settings tab:
    Custom settings - check
    Modify All Network Adapters - check
    network adapter selection - your NIC
    MTU 1500
    TTL - 64
    TCP Receive Window -256690
    MTU Discovery - Yes
    Black Hole Detect - No
    Selective Acks - Yes
    Max Duplicate ACKs - 2
    TCP 1323 Options:
    Windows Scaling - checked
    Timestamps - uncheck
    Advanced Settings tab:
    Max Connections per Server - 10
    Max Connections per 1.0 Server - 20
    LocalPriority - 5
    Host Priority - 6
    DNSPriority - 7
    NetbtPriority - 8
    Lan Browsing speedup - optimized
    QoS: NonBestEffortLimit - 0
    ToS: DisableUserTOSSetting - 0
    ToS: DefaultTOSValue - 240
    MaxNegativeCacheTtl - 0
    NetFailureCacheTime - 0
    NegativeSOACache Time - 0
    LAN Request Buffer Size - 32768
    Then select "Apply Changes" and reboot to take effect
    VERY IMPORTANT TO DO THE FOLLOWING:
    1. Under your LAN connection - properties - general tab, uninstall all the protocols there that you do not need. For a stand alone pc all you need is Internet Protocol TCP/IP.
    2. Open IE and select tools - internet options - connections - LAN settings, make sure NOTHING there is checked.
    3. ALWAYS connect your modem via ethernet (NIC) and make sure you have the latest drivers for your NIC from the manufacturer and set your duplex mode to "auto". If you are using a router make sure you have the latest firmware.
    4. Clean out your temporary internet files with CrapCleaner.
    5. Power cycle your modem i.e. unplug it for at least 15 seconds.
    6. Download, update and scan with SpyBot S&D 1.4 EXACTLY as mnosteele has explained HERE & Ad-Aware SE 1.06 EXACTLY as mnosteele has explained HERE to remove any spyware then install and update SpywareBlaster 3.4 to stay spyware FREE. YOU MUST USE BOTH AD AWARE & SPYBOT TO ENSURE YOU ARE SPYWARE FREE SINCE ONE FINDS WHAT THE OTHER MISSES. If these 2 programs find a lot of things then please post a HijackThis 1.99.1 log for us to look at.
    7. Make sure you do the faster web page tweak in our Help & Tips page.
    8. If you have Zone Alarm as a firewall uninstall it and search your pc for the left over files.
    9. Install Kerio Personal Firewall 2.1.5, it's FREE and uses next to no resources.
    10. Do a FREE online virus scan from Kaspersky Webscan, make sure to check the option to use the EXTENDED DATABASE.
    11. Make sure you have ALL of the latest Windows Updates.
