    Help with Tweaking Values

    After finally fixing my wireless problem, I am going to give tweaking another try. Here are my stats:

    I am using Windows XP and am connecting to a wireless router that is utilizing Bellsouth FastAccess DSL Lite

    MTU: 1500
    TCP Window: 17520 (multiple of MSS)
    RWIN Scaling: 0
    Unscaled RWIN : 17520
    Reccomended RWINs: 64240, 128480, 256960, 513920
    BDP limit (200ms): 701kbps (88KBytes/s)
    BDP limit (500ms): 280kbps (35KBytes/s)
    MTU Discovery: ON
    TTL: 112
    Timestamps: OFF
    SACKs: ON
    IP ToS: 00100000 (32)
    Precedence: 001 (priority)
    Delay: 0 (normal delay)
    Throughput: 0 (normal throughput)
    Reliability: 0 (normal reliability)
    Cost: 0 (normal cost)
    Check bit: 0 (correct)
    DiffServ: CS1 001000 (8) - class 1 (RFC 2474). Similar forwarding behavior to the ToS Precedence field.

    Just need a little help with what to put into the fields in TCPOptimizer. Thanks!
