Internet connection stops working after a while of use/idling until reboot

  1. I've been googling this problem for a week now with no answers. I've done a lot of things in an attempt to solve this problem.

    OK, so lately I've been getting disconnected from the internet. My cable modem is routed through a network hub, and then to my PC.

    I can ping localhost, but cannot ping anything else, such as google.com or even my ISP's DNS server. In the network panel (Windows XP SP3), it says i am connected, but when I check properties I can see that it is not sending and receiving packets at all.

    I've used commands pertaining to "netsh" to clear WINSOCK (and more I just forgot).

    I have no idea as to what has caused this. The only significant thing that has happened prior to the problem was a storm that caused a power outage.

    I'm thinking this is an Ethernet port issue, but a year ago I received the same problem, and somehow it was magically fixed.

    I performed a scan for viruses, malware, and spyware but saw nothing. I then attempted to clean my registry (barely did much) and checked my Hijack This log and it still shows nothing out of the ordinary.

    In Device Manager, it shows no problem with the actual device so I'm clueless...could it be a registry corruption?

    I really need in-depth help because this seems to be a specific problem...


    To put this all in brief:

    1. Says I'm connected to internet.
    2. Cannot send or receive packets.
    3. Cannot ping anything but localhost.
    4. Disconnection seems to be random.
    5. Happens during any state of computer/network use (e.g. Idling, D/Ling, gaming, watching, etc.)
    6. ipconfig /all gives back all OK. Nothing out of the ordinary (looks the same as it was before the problem)
    7. Device manager gives the ethernet port an OK.
    8. Only time problem is solved temporarily is when a reboot is performed on the computer.

    System Specs:

    Microsoft Windows XP Professional Version 2002 SP3

    Intel(R) Core(TM)2 Quad CPU
    Q6700 @ 2.66Ghz
    2.67 GHz, 2.75 GB of RAM

    Motherboard:
    nVidia nForce 780i SLI

    Please someone respond. I have already reinstalled the NIC drivers through safe mode and the conventional way.


    I used the Network Diagnostic Tool for Windows XP showing two versions (one being before the problem and after)

    It seems to me that I can ping my own address, but when pinging the DNS servers and Gateway it just times out. Maybe this will be useful to someone?
