    Hi i am trying to fix a friends laptop of which refuses to connect to their home network, i have not tried it on oher networks but it is obvious the wireless card is working as it can pick up networks in the area.

    when it is set to "obtain ip address automatically" it will say there is no "limited or no connectivity" and when i try to set the dns and ip addresses as on other computers in the house it connects to the network but the internet still wont work.

    ipconfig when the laptop has "obtain ip address automatically":

    Bump after about a day to bring your thread to the front. Bump after an hour to annoy people.

    (from a JohnWill post)

    IP addresses of 0.0.0.0 are normally caused by one of the following.

    Diagnosis:
    1. DHCP Service not running.
    2. Duplicate IP address on the network.
    3. Bad NIC card drivers.
    4. Defective NIC hardware.

    Resolution:
    1. Check Control Panel, Administrative Tools, Services. The DHCP Client service should be Started and its Startup Type should be Automatic.
    2. Turn off ALL of the computers and other network connected devices, reboot the router, then restart all the computers and other network devices.
    3. Check for upgraded drivers and/or reload the Network drivers.
    4. Replace the Network Interface Card.

    1. the dhcp client is correct in services
    2. the ip address is definitely not shared with any other device as this problem has been for a long time and all devices have been reset since problem began
    3. i have tried rolling back, reinstalling and updating the driver
    4. i do not have a spare network card and it is inbuilt to the laptop

    but thanks for help and sorry for the hyperactive bumping :D

    i fear the computer may have spyware problems, the owner bought 'alphawipe' which i have since uninstalled, could u reccomend any programs to get rid of any infections or viruses, mcafee says there are no problems

    You did note that (2) specifically has the router restarting or rebooting while all other devices are off, right?

    The driver for an integrated adapter should be the latest from the PC manufacturer's site.

    I can't help with the potential malware issue because it is my intent when/if I get infected to format the disk, install operating system fresh, ...

    Have you tried an ethernet connection to see what happens there?

    Just for kicks try the following and see if it can scare that 0.0.0.0 IP away.

    (From a JohnWill post)

    TCP/IP stack repair options for use with Windows XP with SP2 or SP3.

    Start, Run, CMD, OK to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

    Reboot the machine.
