    Okay, I'm baffled. Usually I can trouble shoot problems, but not this time.

    I have 8 computers on my network. My main computer (this one) has a very slow upload speed.

    Comcast - 20mb down, 5mb up

    This computer - 25mb down, .17mbps up

    All of the rest will hit 5mbps up consistently.

    Everything I've done here has not worked ...
    • I've plugged the computer straight into the modem
    • Updated built in network adaptor drivers
    • Flushed the DNS: ipconfig /flushdns
    • Put on a new network cable
    • Tried a network cable from a computer that does work fine
    I spent 45 min's on phone with Comcast support.

    I run XP Pro
    All upgrades are current
    i7 4gig ram
    Dual 512k video cards

    Computer worked fine few weeks ago. But now it's not.

    I do not have an additional slot to install a new NIC card.

    What do I try next?
    What else do you need to know to help me trouble shoot this?

    Thanks alot for your help.
