    Dsl Connection tweak, Help Please.

    Hey guys, I reinstalled my windows recently and the download speeds haven't been the same. I was really hoping if you guys could help me tweak my connection to what it was before i reinstalled my windows. My connection is a dsl broadband 3Mbs from Belll Sympatico. The website is http://www.bell.ca/shopping/internet...sShpInt_Access.

    I did the TCP/IP Analyzer test and here are the results, Any help would be greatly appreciated.

    TCP options string = 020405a00103030201010402

    MTU = 1480
    MTU is optimized for Windows XP PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

    MSS = 1440
    MSS is optimized for Windows XP PPPoE DSL broadband. If not, consider raising your MTU value.

    Default TCP Receive Window (RWIN) = 257760
    RWIN Scaling (RFC1323) = 2 bits (scale factor of 4)
    Unscaled TCP Receive Window = 64440

    RWIN is a multiple of MSS
    Other RWIN values that might work well with your current MTU/MSS:
    506880 (MSS x 44 * scale factor of 8)
    253440 (MSS x 44 * scale factor of 4)
    126720 (MSS x 44 * scale factor of 2)
    63360 (MSS x 44)

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

    Your TCP Window limits you to: 10310.4 kbps (1288.8 KBytes/s) @ 200ms
    Your TCP Window limits you to: 4124.16 kbps (515.52 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON

    Time to live left = 58 hops
    TTL value is ok.

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

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




    Btw I'm using TCP Optimizer program to tweak it. Any help would be greatly appreciated.

    -Thanks-

    Try increasing your MTU first with these TCP Optimizer custom settings:

    General Settings tab:
    Custom settings - check
    Modify All Network Adapters - check
    network adapter selection - your NIC
    MTU - 1500
    TTL - 64
    TCP Receive Window - blank
    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 - 80
    MaxNegativeCacheTtl - 0
    NetFailureCacheTime - 0
    NegativeSOACache Time - 0
    LAN Request Buffer Size - 32768
    Then select "Apply Changes" and reboot to take effect

    Your MTU is fine, you have PPPoE DSL and it sould be 1480, so try the following:

    General Settings tab:

    Custom settings - check
    Modify All Network Adapters - check
    network adapter selection - your NIC
    MTU - 1480
    TTL - 64
    TCP Receive Window - 63360
    MTU Discovery - Yes
    Black Hole Detect - No
    Selective Acks - Yes
    Max Duplicate ACKs - 3
    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 - 92
    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, Ad-Aware SE 1.06, ewido anti-spyware 4.0 & SUPERAntiSpyware to remove any spyware then install and update SpywareBlaster 3.5.1 to stay spyware FREE.

    7. If you aren't currently using a firewall or anti-virus profram then I suggest you install Comodo Firewall and Active Virus Shield - (setup instructions HERE), both are FREE and offer excellent protection.

    8. Do a FREE online virus scan from BitDefender Online Scan and remove all that it finds.

    9. Make sure you have ALL of the latest Windows Updates.

    10. Just an FYI, if you are using Zone Alarm for a firewall it can noticeably drop your speeds.

    Hey Monsteele52, thanks for your tips they have helped the download speed increase somewhat but the problem i'm having now is that my connection keeps timing out. Whenever I download something, it just freezes out or times out for some reason. Is their a way to fix this?

    -Thanks-.
