    Hi,

    I know this is a common problem from looking around, but none of the solutions I’ve found seem to work.
    My PC was previously connecting to the internet fine but has now stopped and will only connect to unidentified network with limited connectivity.
    I’m using Vista 64 with the sky router.
    I’m connected to the router by Ethernet cable, though there are 2 laptops that connect fine wirelessly one on vista and one on xp.
    I would greatly appreciate it if anyone is able to help, will provide any more information that you require.
    Oh tried unplugging the router and re starting my computer and it didn’t work.
    Thanks for any help.

    TCP/IP stack repair options for use with Windows Vista.

    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 type the following commands:

    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.



    Let's see this after the reset using the wired connection. Make sure you have a known good cable connecting to a known good port on the router.


    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.

    Try connecting to the other Ethernet connection, perhaps that adapter has died? You may also want to try reloading the drivers for the NIC.
