    TCP options string = 020405b40103030201010402
    MTU = 1500
    MTU is fully optimized for broadband.
    MSS = 1460
    Maximum useful data in each packet = 1460, which equals MSS.

    Default Receive Window (RWIN) = 202940
    RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
    Unscaled Receive Window = 50735

    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)
    128480 (MSS x 44 * scale factor of 2)
    64240 (MSS x 44)
    bandwidth * delay product (Note this is not a speed test):

    Your RcvWindow limits you to: 8117.6 kbps (1014.7 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 3247.04 kbps (405.88 KBytes/s) @ 500ms
    MTU Discovery (RFC1191) = ON
    Time to live left = 116 hops

    TTL value is ok.
    Timestamps (RFC1323) = OFF
    Selective Acknowledgements (RFC2018) = ON
    IP type of service field (RFC1349) = 00000000 (0)

    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 - 64240
    MTU Discovery - Yes
    Black Hole Detect - No
    Selective Acks - Yes
    Max Duplicate ACKs - 2
    TCP 1323 Options:
    Windows Scaling - uncheck
    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.

    I did use all the setting mentioned but the speed seemed slow and it was after testing it. I changed the RWIN value to 414640 and checked windows scaling. Here is the TCPAnylizer dump.

    I used an RWin calculater to calculate the RWIN value.

    i gave you an rwin value what's the point of asking my help when you are not going to even follow what i suggested what speed test do you test at what was the resault???

    I did test your settings. I used this speed test.

    http://rochester.speedtest.frontiernet.net/

    I tested alot of settings and the RWIN calculater came up with 414640.

    Basically I am receiving the same results.

    5500
    350


    Where do these settings go? They aren't under advanced settings.

    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
