    1st post "HI ALL"

    Hi all,

    My name is Steve, have been reading and using tools on forum and decided to join.

    Present TCP analize

    TCP options string = 020405800103030001010402
    MTU = 1448
    MTU is not fully optimized for broadband. Consider increasing your MTU to 1500 for better throughput.

    MSS = 1408
    MSS is not fully optimized for broadband (although it might work well for slower connections). Consider increasing your MTU value.

    Default Receive Window (RWIN) = 32768
    RWIN Scaling (RFC1323) = 0 bits
    Unscaled Receive Window = 32768

    For optimum performance, consider changing RWIN to a multiple of MSS.
    Other values for RWIN that might work well with your current MTU/MSS:
    518144 (MSS x 46 * scale factor of 8)
    259072 (MSS x 46 * scale factor of 4)
    129536 (MSS x 46 * scale factor of 2)
    64768 (MSS x 46)
    bandwidth * delay product (Note this is not a speed test):

    Your RcvWindow limits you to: 1310.72 kbps (163.84 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 524.288 kbps (65.536 KBytes/s) @ 500ms
    MTU Discovery (RFC1191) = ON
    Time to live left = 52 hops

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

    Questions:

    1. Why does MTU State 1448 when all reg & router is set to 1492
    2. How does this look for performance

    TIA,

    Who is your proivder and advertised speed.

    Assuming you are on dsl what modem do you own the mtu could be set wrong there as well.. What windows version you are running??

    Try thease and take another analyzer if still no go ty this.
    if mtu is not 1492 or 1480 try 1500 forr mtu and take another anlayzer afte reboot afte saving changes

    General Settings tab:

    Custom settings - check
    Modify All Network Adapters - check
    network adapter selection - your NIC
    MTU - 1492
    TTL - 64
    TCP Receive Window - 63888
    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.

    mccoffe or any help

    Ok did all as advised previously here are results:

    DslReports TweakTest

    1. Your Tweakable Settings:
    Receive Window (RWIN): 63888
    Window Scaling: off
    Path MTU Discovery: ON
    RFC1323 Window Scaling: OFF
    RFC1323 Time Stamping: OFF
    Selective Acks: ON
    MSS requested: 1408
    TTL: unknown
    TTL remaining: 53
    TOS/TOS subfield: 0
    TOS/Flags:

    2. Test 1024001 byte download
    Actual data bytes sent: 1024001
    Actual data packets: 729
    Max packet sent (MTU): 1448
    Max packet recd (MTU): 1448
    Retransmitted data packets: 0
    sacks you sent: 0
    pushed data pkts: 34
    data transmit time: 3.159 secs
    our max idletime: 371.7 ms
    transfer rate: 284300 bytes/sec
    transfer rate: 2274 kbits/sec
    This is not a speed test!
    transfer efficiency: 100%

    Notes and recommendations:
    RWIN is in range
    Looking good

    Notes and recommendations:
    Good data stream (no/few rexmits)

    SpeedTest:
    Your Throughput

    Download = 2.563 Mbps
    Upload = 437.58 kbps

    Any thoughts or help as to why speedguides mtu wont change??
    Thx
