    its made a hope of my self to tweaks future more,had tried tcp for beginner firstly ,but its looks nothing different than before,wondering me to tweaks more,Then Olla!...I find the calculations like ever seen,its similar w/cablenut calculations,but more advanced because Rwin and the parameters,

    would you like to giving a hand, tweaks my connection!?...plz

    Im in a telkomsel flash(Indonesia) wirreles broadband conn(HSDPA) 3200/384 (this the advertised my broadbands)

    I got tcp analizer like below:

    MTU - 1500
    TTL - 64
    Checksum Offloading : enabled 0
    Windows Scaling - check
    TCP Receive Window - 128480
    MTU Discovery - Yes
    Black Hole Detect - No
    Selective Acks - Yes
    Max Duplicate ACKs - 2
    TCP 1323 Options:
    Timestamps - uncheck

    Advanced Settings :

    Speed performance of cellphone internet service depends largely on clarity and strength of signals. High Rwin with packet losses cause speed to fall greatly.

    Using Cablenut with XP SP3 means you must leave the field of Default Receive Window a blank. If not, the value entered for this field will override that set for Tcp Window Size and Global Tcp Window Size.

    If bandwidth is 3.2 mbps and latency is 572ms, I do not see how Rwin should be less than 256960.
