    10 mbps can't get a good speed test

    I just upgraded from charter to 10mbps from 3mbps, seems when i do a speed test, I have been to a bunch of them, none ever register faster then 7mbps I have giganews and i tried to download from my normal newsgroups wich i get great sppeds from, and they don't seem to be much differnt, I tried the optimiser from this site and it didnt seem to do anything, they gave me a new modem since the one i had was old and it wouldnt support the 10 connection, I think the modem is ok, but I am not sure what is wrong.

    here is some test I have did. for help, any help is appeciated!

    Trace complete.

    C:\>



    TCP options string = 020405b40103030401010402

    MTU = 1500
    MTU is fully optimized for broadband.

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

    Default TCP Receive Window (RWIN) = 1027840
    RWIN Scaling (RFC1323) = 4 bits (scale factor of 8)
    Unscaled TCP Receive Window = 64240

    RWIN is a multiple of MSS
    Other RWIN values 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 (Note this is not a speed test):

    Your TCP Window limits you to: 41113.6 kbps (5139.2 KBytes/s) @ 200ms
    Your TCP Window limits you to: 16445.44 kbps (2055.68 KBytes/s) @ 500ms

    MTU Discovery (RFC1191) = ON

    Time to live left = 54 hops
    TTL value is ok.

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

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

    No router just norton internet security wich i have turned off to test also, and i come up with the same results.

    I have tried downloading windows vista from microsofts site thinking it should have a good connection, but it usallt starts at 7 and dropps to 3-5

    BTW I live in MO, incase you didnt see the starting trace route

    Thanks in advance for any help.

    The 24ms at your modem indicates possible electromagnetic interference on your modem from some other electrical device. Try isolating your modem a few feet away from other devices.

    Your TCP Receive Window (RWIN) at 1027840 is too high. Set it to 256960. This will give you a max latency of 205ms for 10 mbps bandwidth.

    I went to one site for the one above, a Chicago server! and the bottom one from Atlanta Ga. All of these was from speakeasy.net

    and I went to speedtest.net for these

    Now this is what I want!

    Thank you so much!!!! that must have been it.

    thanks again, if you see anything else that i should change let me know

    my stats now

    Once again thank you so much.
