    Hi,

    I am hoping that someone can help me.
    We have three computers at home two which are connected to router and working fine and my laptop.
    My laptop was connecting to my home wireless network until my daughter used it last. Now it will not connect at all
    I used to have to follow the steps below for some reason and then it would connect fine:
    Wireless network connections
    Change advanced settings
    Wireless Networks tab
    I would have to tick the checkbox USE WINDOWS TO CONFIGURE MY WIRELESS NETWORK SETTINGS
    Then into properties for my wireless network and in association retype my password and then it would connect. (it seemed like to much work every time but it still worked)
    There was other networks in the list which i deleted and wireless network connection shows that the network connection strength is excellent but it just seems to get stuck aquiring the network address. I have tried repair etc.

    Can someone please help me with this as maybe it's just something simple!! :(

    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).
    Make and exact model and hardware version of any other network equipment, like a repeater, a booster, hi-gain antenna, etc.
    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?
    • For wireless laptops, have you made SURE the wireless switch is on?
    • For wired connection issues, have you booted in Safe Mode with Networking to see if that changes the symptoms?
    • 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 74.125.45.100

    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.

    Let's start by enabling DHCP.


    Select Start > Settings > Network Connections.

    • Double-click the Connection icon of the connection you wish to modify to open the Connection Status window.
    • Click the Properties button to open the 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.


    Using a wired connection, see if that changes things, and post the pings and the IPCONFIG /ALL again.

    I called my IT support and they have logged a callback as it was closing time it used to work though but I had to go into internet connetions, click on the wireless connection, go thru to the screen where it asked for password and had to click>use windows to configure my wireless networks and then properties for preferred networks and Ok the password if that helps, there were two other networks there from previous laptop owner so when it started playing up I deleted those networks and hasnt worked since and will not allow a system restore either??

    Well, I see two issues.

    One is that you don't have DHCP enabled for the network, do this for each network connection.


    Select Start > Settings > Network Connections.

    • Double-click the Connection icon of the connection you wish to modify to open the Connection Status window.
    • Click the Properties button to open the 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.



    Two, you have ICS enabled, we need to disable that.

    Disabling Internet Connection Sharing



    Finally, I think we probably should do a stack repair after fixing all that.


    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, each followed by the Enter key:

    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.




    See if that helps...

    Disable ICS. You apparently have it enabled on the wireless connection, and it is over-riding the Dhcp setting for the ethernet.
