    This started a few days ago when i turned my computer on, had worked just fine the night before. My computer is assigning its own IP address according to my ISP. They told me that any IP beginning with 164 is self-assigned. I have checked my ipv4 and ip6 and they are both auto configuring IP/DNS.

    I'm on another computer at the moment on the same modem. I'm running Windows Vista 64 Home.

    WELCOME TO TSG:
    Any hardware/software changes ?
    May we see:
    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)



    In the command prompt window that opens, type the following command:

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter to copy the contents to the clipboard.
    Paste the results in a message here.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    And just to eliminate the possibility of stack corruption :
    Stack repair for XP and Vista.
    Courtesy of Johnwill of the Networking forum.


    TCP/IP stack repair options for use with Vista or Windows 7

    Start, All Programs\Accessories and right click on Command Prompt, select "Run as Administrator" to open a command prompt.

    In the command prompt window that opens, type the following commands, each followed by the Enter key:

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset IPv4 TCP/IP stack to installation defaults: netsh int ipv4 reset reset.log

    Reset IPv6 TCP/IP stack to installation defaults: netsh int ipv6 reset reset.log

    Reboot the machine.

    Ok;Let's make sure all is set correctly:
    Configure DHCP for Windows Vista.
    1. Click on the Start menu, and select Control Panel.
    2. Click on Network and Internet. (Skip this step if you do not see this Control Panel item.)
    3. Click on Network and Sharing Center.
    4. Click on Manage network connections.
    5. Right click on Local Area Connection and choose Properties. If Windows say it needs your permission to continue, click Continue.
    6. Select Internet Protocol Version 4(TCP/IPv4) and click Properties.
    7. Select Obtain an IP address automatically.
    8. Select Obtain DNS server address automatically.
    9. Click OK to close the TCP/IP Properties window.
    10. Click OK to close the Local Area Connection Properties window.
    11. Click Close to close the Network Connections window.
    12. Click Close to close the Control Panel window.
    13. Restart your computer.

    I do not have Vista,but see if you can disable the ipv6 function
    See if you can do an ipconfig /release and ipconfig /renew
    Last two things to try.
    I device manager uninstall the ethernet adapter and re-boot.
    Results of stack repair ?
    Try a system restore,to before the problem..

    seems to be no change after the stack repair, and i have no restore points for some reason( was going to do this to begin with). I know the ip/dns settings are set to automatically obtain as this was one of the steps my ISP sent me through. I can/will disable the Ipv6 now.

    Edit: Disabled ipv6, released then tried to renew and it says: an error occured while renewing interface local area connection : unable to contact your DHCP server. request has timed out.
