    Question newbie need help for settings

    help please....


    i'm using CDMA/GPRS cell phone as a modem, the signal bar is almost full (minus 1 or 2 off full bar), connected via USB port.
    my ISP's advertised speed is 153 Kbps.
    my OS is WinXP Pro SP2 + update up to Feb2007, Comodo Firewall & Free AntiVir.
    i can download at very good speed but very slow for browsing.

    i've tried TCPOptimizer, but in General Settings - Network Adapter selection there's nothing i can choose, it's completely blank. and everytime i change MTU it get blank again after reboot.

    here's my TCP/IP Analyzer Test result:

    =========================================

    Do this test. When test is completed, click the 'Statistics' button and post the pop-up report. We need to check your round trip time:

    Your round trip time is very high at 1143ms and your MTU is 1024 (984+40).

    Where are you located?

    Do this test again and post the pop-up report under the 'More Details...' button to check your RWIN values.

    Try the following with TCP Optimizer:

    General Settings tab:
    Custom settings - check
    Modify All Network Adapters - check
    network adapter selection - your NIC
    MTU 1024
    TTL - 64
    TCP Receive Window - 23616
    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 - 4
    Max Connections per 1.0 Server - 4
    LocalPriority - 1
    Host Priority - 1
    DNSPriority - 1
    NetbtPriority - 1
    Lan Browsing speedup - optimized
    QoS: NonBestEffortLimit - 0
    ToS: DisableUserTOSSetting - 0
    ToS: DefaultTOSValue - 96
    MaxNegativeCacheTtl - 0
    NetFailureCacheTime - 0
    NegativeSOACache Time - 0
    LAN Request Buffer Size - 16384
    Then select "Apply Changes" and reboot to take effect

    After reboot, test your speed at this link using the test server in Indonesia:
