    Hi and welcome to TSG:
    In order to answer your questions,we will need to know a bit more about your environment:
    This is from a Johnwill post.Answer as many of these points as you can.
    The “Johnwill” need to know about your environment questionnaire:

    Please supply the following info, exact make and models of the equipment please.
    .

    What country are you located in.
    Name of your ISP (Internet Service Provider).
    What is the expected Upstream/Downstream speed for your ISP Connection?
    Make and exact model of the broadband modem.
    Make and exact model and hardware version of the router (if a separate unit).
    Model numbers can usually be obtained from the label on the device.
    Connection type, wired or wireless.
    If wireless, encryption used, (none, WEP, WPA, or WPA2)
    Make and model of your computer.
    Version and patch level of Windows on all affected machines, i.e. XP-Home (or XP-Pro), SP1-SP2, Vista, etc.
    The Internet Browser in use, IE, Firefox, Opera, etc.




    Please give an exact description of your problem symptoms, including the exact text of any error messages.

    If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms? Have you disabled all encryption on the router to see if you can connect that way? Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?

    If there are other computers on the same network, are they experiencing the same issue, or do they function normally?




    On any affected computer, I'd also like to see this:

    Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

    Type the following commands:

    PING 206.190.60.37

    PING yahoo.com

    NBTSTAT -n

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter.
    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.
    __________________
    In addition,if you have any firewalls running,disable them and see if that makes a difference on this issue.

    You have DHCP disabled on that machine for the wireless connection.


    Select Start > Settings > Network Connections.

    • Double-click the Connection icon of the connection you wish to modify to open the Local Area Connection Status window.
    • Click the Properties button to open the Local Area Connection Properties window.
    • Click to highlight Internet Protocol (TCP/IP).
    • Click the Properties button to open the Internet Protocol (TCP/IP) Properties window.
    • TCP/IP Properties window, IP Address tab
    • Select Obtain an IP address automatically.
    • Select Obtain DNS server address automatically.
    • Click OK to return to the Local Area Connection Properties window.
    • Click OK to return to the Network Connections window.

    Reboot and see if you can connect now.

    I suspect that an ipconfig of the working PC will show a private IP address because it is properly connected to and communicating with the router.

    As long as you have the problem PC set to a static public IP address you are not likely to get very far. Certainly not unless there are some other details about your network that you omitted.

    Terry's right, if configuring it for DHCP doesn't get a connection, it's unlikely picking an IP address and doing a manual configuration will do any better. The only reason that the wireless connection doesn't say "limited or no connectivity" is because it never does if you configure the IP address manually, but you didn't fix anything.

    it has worked fine for the past year ive rebooted a couple of times completely but this time laptop spat the dummy and locked up in a menu for starting in safe mode and so on,no matter which option i chose it ended right back at that menu this coupld be the problem cause the only way i could get it going again was to kill it by removing battery's including cmos one and rebooting it all over again.

    Let's try a stack repair.


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

    Start, Run, CMD to open a command prompt:

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

    Note: Type only the text in bold for the following commands.

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

    Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog

    Reboot the machine.

    Disable encryption on the router and try to connect. Assuming success you should be able to re-enable encryption and reconnect.
