    System:
    Dell 1.66Ghz 1GB Ram laptop
    Intel PRO/Wireless 3945ABG Network Connection
    Windows XP SP2


    I have a wireless connection at home with a number of laptops connected, have all been working fine for a year or so. One of the laptops has stopped connecting to the internet and I have searched high and low for a solution.

    The adapter (Intel PRO Set Wireless) has an icon saying I am connected to my provider at 54mbps with an 'excellent' signal quality but the ip address is set at 169.254.195.180. Another icon in the tray starts stating 'acquiring network address' for a long time and then fails stating 'limited or no connectivity'.

    Using the various troubleshooters, I have received a message stating 'the wireless adapter failed to get a valid ip address. This can be due to authentication failure, incorrect wireless security passwords or because of a DHCP server malfunction'. I have re-entered the correct passwords to no avail, and the other 2 laptops are working and connecting fine to the same provider.

    I have also tried the cmd prompt and the usual ipconfig release and renew but it simply states:

    >ipconfig /release

    Windows IP Configuration

    No operation can be performed on Local Area Connection while it has its media di
    sconnected.

    Ethernet adapter Local Area Connection:

    Media State . . . . . . . . . . . : Media disconnected

    Ethernet adapter Wireless Network Connection:

    Connection-specific DNS Suffix . :
    IP Address. . . . . . . . . . . . : 0.0.0.0
    Subnet Mask . . . . . . . . . . . : 0.0.0.0
    Default Gateway . . . . . . . . . :

    >ipconfig /renew

    Windows IP Configuration

    No operation can be performed on Local Area Connection while it has its media di
    sconnected.
    An error occurred while renewing interface Wireless Network Connection : unable
    to contact your DHCP server. Request has timed out.

    I have also tried the WinsockFix and IspFIx programmes available on the internet for download. Again no success!

    On my Sony vaio laptop, which is working fine, I get the following details:

    Wireless LAN adapter Wireless Network Connection:

    Connection-specific DNS Suffix . :
    IPv4 Address. . . . . . . . . . . : 192.168.0.4
    Subnet Mask . . . . . . . . . . . : 255.255.255.0
    Default Gateway . . . . . . . . . : 192.168.0.1



    Anybody have any words of wisdom before I throw the laptop out of the window!:mad:

    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.
