    Analyzer results

    Why is the Rwin completey off? it says:

    MTU = 1500
    MTU is fully optimized for broadband.

    MSS = 1460
    Maximum useful data in each packet = 1460, which equals MSS.

    Default Receive Window (RWIN) = 65535
    RWIN Scaling (RFC1323) = 0 bits
    Unscaled Receive Window = 65535
    Note: Under Windows 9x, if you have RWIN set to any other value, and the Analyzer reports 65535 you might need to install the MS Vtcp386 fix.
    For optimum performance, consider changing RWIN to a multiple of MSS.
    Other values for RWIN that might work well with your current MTU/MSS:
    513920 (MSS x 44 * scale factor of 8)
    256960 (MSS x 44 * scale factor of 4)
    128480 (MSS x 44 * scale factor of 2)
    64240 (MSS x 44)

    bandwidth * delay product:
    Your RcvWindow limits you to: 2621.4 kbps (327.675 KBytes/s) @ 200ms
    Your RcvWindow limits you to: 1048.56 kbps (131.07 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON

    Time to live left = 48 hops
    TTL value is ok.

    Timestamps (RFC1323) = OFF

    Selective Acknowledgements (RFC2018) = ON

    IP type of service field (RFC1349)= 01011100
    Precedence (priority) = 010 (immediate)
    Delay = 1 (low delay)
    Throughput = 1 (high throughput)
    Reliability = 1 (high reliability)
    Cost = 0 (normal cost)

    And I have set it to 373760...by the way I'm on XP

    Sackopts must be set to 1 in Cablenut if RWIN is 65535 or higher.

    OOPS I meant TCP1323Opts needs to be 1.
