    -Genuine Windows Vista Home Premium (32-bit)
    - Intel Core 2 Duo processor E4500 (2.2GHz)
    - 2GB DDR2-667MHz dual channel SDRAM (2x1024)
    - 256MB NVIDIA GeForce 8400GS, DVI-I, HDMI
    - 400GB 7200 rpm SATA 3Gb/s hard drive
    - 16X DVD+/-R/RW SuperMulti drive
    - 15-in-1 memory card reader, USB, headphone port
    - Integrated 7.1 channel sound w/front audio ports
    - HP wireless keyboard and HP wireless optical mouse

    Cox HSI Premier Service 12down/1up
    Direct-No Router
    Modem to Computer connection: Ethernet Cable
    AMBIT U10C018
    Cable RF MAC Addy: 00197E3C4E18

    When I first start up MS Vista I get speeds of about 15/1 with Ping times in the 20-30ms range.

    After a few mins I notice things starting to slow down and taking longer to load.

    I run another speed test from Speedtest.net and find that I have dropped to about 10/.5 and my Ping times have gone up o over 300ms!!

    I can then shut down Vista and when I start it back up...I am back down to what I should have in the 15/1 25ms range?

    I had two techs out from Cox yesterday and they basicially said "This is a hardware/software problem...all of your readings on our test equipment are just fine...your signal strength is excellent"

    The suggested that I contact Customer Support at HP...I did so and explained the problem only to have the Tech Support person tell me that "You have a Cable problem, not a hardware problem...call your ISP"!!!

    I havn't tried to contact MS Vista Support, which would have been my last resort until I found this excellent Forum.

    Can anyone help me....it is SO frustrating to have an Expensive ($56.95/mo) superfast connection capable of such high speeds (I saw over 25kb/s Download speed once!) dragged down like this and not be able to determine why or what to do to correct the problem!

    Here are two representative tests, done at two different times, on Speedtest.net: The first right after I started up Vista and the second after it had been running for 10mins (Note the tremendous drop in especially the Upload speed and the verey sharp increase inPing time in ms)



    Please help me figure out what is going on here and how to correct it!
