    Router does not have a valid IP configuration


    My computer wouldn't wake from sleep mode a few days ago so I hard rebooted it. When it booted I no longer had internet access.

    My local area connection was listed as an unidentified network with no network access. I used the troubleshoot tool on the connection and it returned "the router does not have a valid IP configuration". I could not change the network from public to home/private.

    I am able to connect to the internet using the same router and cable on this laptop. The wireless is also working fine.

    I have tried:
    disabling and enabling the network adaptor, DHCP and the local connection
    updating the network card drivers
    disabling ipv6 in local connection
    Resetting the router to factory settings
    I disabling bonjour (I do not have and have never installed mcafee)
    clearing the TCP/IP stack with netsh int ip reset
    using ipconfig /release /flushdns /renew
    system restoring to before the issue occurred
    doing a clean install of windows (it saved my old files under windows.old - I assume this is still a clean install)

    I am running windows 7 home premium 64, my network card is an Intel 82567LF-2 Gigabit, the router is a Thomson TG782T and I am using Bigpond ADSL2+.

    It's been a couple of days and I'm well out of my depth. I didn't expect the issue to continue after a clean install. Any help would be really appreciated. Attached is the ipconfig I get. Attachment 288972

    If you could attach your ipconfig please because I can't see it

    This can help us determine possible causes

    Try "system restore" . System Restore
    Go back in time to a date/time when everything was fine.

    Sorry...you already did.

    Please post ipconfig.txt

    Disconnect network cable from desktop and put in laptop. Be sure the laptop is NOT connected wirelessly! Does that work and you can access internet? If so networkcable is fine and connected fine in router.

    Connect it in desktop again as usual.

    BTW ipconfig output showed me tcp/ip is working. LAN adapater is working (driver is most likely fine).

    Only problem so far.... DHCP can't get an ip address from router

    Do you know the ip address of your router? If not do ipconfig on working laptop and look at "default gateway" line. Give me that address please

    The router's IP Address. . . . . . . . . . . . : 10.0.0.3
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 10.0.0.138
    DHCP Server . . . . . . . . . . . : 10.0.0.138
    DNS Servers . . . . . . . . . . . : 10.0.0.138

    I don't think it's a problem with the connection, cable or the router because I've been posting using the ethernet on this laptop. I wasn't using ipconfig /all. I've attached the results.

    Have you checked for recent drivers on the ethernet NIC or a firmware update for your router? If you did a clean install these should be the culprits in my opinion.

    Just as a precaution, disable any firewall applications that may be installed as they can block DHCP offers

    looks all fine to me.
    Is service "DHCP-client" started, and is service "DNS server" started?. You can check by running services.msc
    if they are not running: "Network Store Interface Service" is running? If they are not running try to start them manually there and post error message

    All services described above have startup type "automatic"?
