    TCP Optimization Help

    Hello everyone. This is my first post here, and I was looking for some help with my internet problems. I just got my computer back from repair, with a fresh install of Vista on it...and I must say, my download and surfing speeds are INCREDIBLY slow. Here are my analyzer results: TCP Analyzer Results
    Tested on: 08.28.2009 13:38
    IP address:
    Client OS: Windows Vista

    TCP options string: 020405b401010402
    MSS: 1460
    MTU: 1500
    TCP Window: 17520 (multiple of MSS)
    RWIN Scaling: 0 bits
    Unscaled RWIN : 17520
    Recommended RWINs: 64240, 128480, 256960, 513920, 1027840
    BDP limit (200ms): 701kbps (88KBytes/s)
    BDP limit (500ms): 280kbps (35KBytes/s)
    MTU Discovery: ON
    TTL: 50
    Timestamps: OFF
    SACKs: ON
    IP ToS: 00000000 (0)

    I'm running Vista (as stated) and my service provider is RoadRunner (Cable internet). I'm not sure on the exact advertised speeds, but I know it's much faster than what I'm currently running at. Also, I'm on a wireless connection as I have no way of directly hooking up to the router. Thanks in advance!

    Tracing route to []
    over a maximum of 30 hops:

    1 8 ms 7 ms 9 ms
    2 * * * Request timed out.
    3 * * * Request timed out.
    4 * * * Request timed out.
    5 * * * Request timed out.
    6 * * * Request timed out.
    7 * * * Request timed out.
    8 * * * Request timed out.

    From what I can see...something HAS to be wrong with my connection. This happens when I run a tracert to anywhere. What can be done?!
