    Hi,
    I have received your site address from Mr Atilla Baysal who praised your site very much. I am living in Turkey and using XP SP3, 1024 Kbps/256 Kbps ADSL wireless. I expect your help on tweaking my connection.

    MTU = 1492
    MTU is optimized for PPoE DSL broadband. If not, consider raising MTU to 1500 for optimal throughput.

    MSS = 1452
    MSS is optimized for PPPoE DSL broadband. If not, consider raising your MTU value.

    Default TCP Receive Window (RWIN) = 65340
    RWIN Scaling (RFC1323) = 0 bits
    Unscaled TCP Receive Window = 65340

    RWIN is a multiple of MSS
    Other RWIN values that might work well with your current MTU/MSS:
    511104 (MSS x 44 * scale factor of
    255552 (MSS x 44 * scale factor of 4)
    127776 (MSS x 44 * scale factor of 2)
    63888 (MSS x 44)

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

    Your TCP Window limits you to: 2614 kbps (327 KBytes/s) @ 200ms
    Your TCP Window limits you to: 1045 kbps (131 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON

    Time to live left = 40 hops
    TTL value is ok.

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

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

    sincerly yours

    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 - 1
    Host Priority - 1

    NegativeSOACache Time - 0
    LAN Request Buffer Size - 32768
    Then select "Apply Changes" and reboot to take effect
