    My computer is a Gateway C NX570X notebook that has worked fine for about a year and a half now. It is running Windows Vista Home Premium and my ISP is Comcast.

    On the toolbar at the bottom of the screen it shows that I am connected to the Internet with the two little computer screens and the globe in front of them. Nonetheless, it still can't connect to the internet. When I run network diagnostics i get the message "Windows has confirmed that this computer is currently experiencing a network connectivity problem" and "Windows found a problem that cannot be repaired automatically. Contact your Internet Service Provider or network administrator for help..."

    The problem is isolated to my computer because my other computer connects to my home network fine...as I am posting this...please help!

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

    Name of your ISP (Internet Service Provider).
    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)
    Version and patch level of Windows on all affected machines, i.e. XP (Home or Pro), SP1-SP2-SP3, Vista (Home, Business, Ultimate), 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?
    • For wireless issues, 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 on separate lines, following each one with the Enter key:

    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.

    The working computer has that same set of DNS servers:

    ?

    See if these make any difference ...

    (From a JohnWill post)

    TCP/IP stack repair options for use with Vista.

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

    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.

    Try these simple tests.

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

    In the command prompt window that opens, type type the following commands one at a time, followed by the Enter key:

    NOTE: For the items below in red surrounded with < >, see comments below for the actual information content, they are value substitutions from the previous IPCONFIG command output! Do NOT type <computer_IP_address> into the command, that won't work.

    IPCONFIG /ALL

    PING <computer_IP_address>

    PING <default_gateway_address>

    PING <dns_servers>

    PING 206.190.60.37

    PING yahoo.com


    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.

    <computer_IP_address> - The IP Address of your computer, obtained from the IPCONFIG command above.

    <default_gateway_address> - The IP address of the Default Gateway, obtained from the IPCONFIG command above.

    <dns_servers> - The IP address of the first (or only) address for DNS Servers, obtained from the IPCONFIG command above.


    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 please check to make sure the working PC has the same set of DNS servers. Also ...

    Make sure the following services are Started (Control Panel - Administrative Tools - Services).

    DNS Client
    Network Location Awareness
    Remote Procedure Call (RPC)

    Thanks for checking the services and DNS servers on the other machines.

    All that output looks good, but you missed that last two pings ...

    I assume that the first will still work and the 2nd will still fail, but let's not rely on my assumptions. :)

    Check your Services are Started on all PCs:
    • COM+ Event System (for WZC issues)
    • Computer Browser
    • DHCP Client
    • DNS Client
    • Network Connections
    • Network Location Awareness
    • Remote Procedure Call (RPC)
    • Server
    • TCP/IP Netbios helper
    • Wireless Zero Configuration (XP wireless configurations)
    • WLAN AutoConfig (Vista wireless configurations)
    • Workstation

    Note: You can check the services in Control Panel, Administrative Tools, Services.

    All of these services should be started, and their startup type should be automatic (or perhaps manual).

    If a service is not running, open it's properties and check the dependencies. Check each of the dependencies and see which one is preventing the service from running. Checking the event log is also a good idea here, there may be clues to what is failing.

    Make sure you have the latest driver from Gateway's web site for your Intel wireless adapter. If you already have the latest driver use Device Manager to uninstall it; reboot and let Windows discover the adapter and reinstall the driver.

    What, if any, non-Windows firewall or security suite do you have on this PC? What one, if any, previously existed but was uninstalled?

    Try Safe Mode with Networking to see if there is any improvement.
