    Hi all,
    I purchased a used IBM T41 laptop with WinXP and everything was working fine: cable and wireless internet, Dvd reader , wireless signal (like antenna) was flashing at the bottom of the screen, ….
    I had some problem and reinstalled OS: deleted partition and formatted into NTFS, install fresh WinXP.
    I didn’t get any error during installation, but some problem came after: internet, wireless connection, USB drivers, DVD reader and many other.
    I couldn’t find network adapter name in the Device manager.
    To fix this problem I download drivers from IBM site and try one by one to install it.
    Finally my internet start to work and I do not have any yellow question mark in Device Manger, but wireless internet and dvd writer do not work.
    Network Adapter( in the Device Manader) and Network Connection display only cable internet device and do not have Wireless device type. Also, I have Wireless Link and Wireless Network icons on the Control panel.


    Why wireless doesn’t work? How can I fix it?
    Is this possible that my laptop did not have wireless card before?
    Is this possible that card stopped to work after reformatting to NTFS?

    Thank you

    Hold the Windows key and press R, then type devmgmt.msc

    Please respond to all the following steps.

    1. Under Network adapters, please tell me all the devices listed.
    2. Are there any devices under Network adapters that have a red x displayed?
    3. Also, are there any devices anywhere in the Device Manager display with yellow ? or ! displayed?



    I'd also like to see this.

    Hold the Windows key and press R, then type CMD to open a command prompt:

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

    Note that there is a space before the /ALL, but there is NOT a space after the / in the following command.

    IPCONFIG /ALL

    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.

    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.

    Hi John,

    I don’t have any display with yellow ? or ! under Device Manager..
    I did some dummy job. I run through Find New Hardware and try to install each existing wireless network connector. All of them are failed, and I Disabled all of them instead of delete. So, now I have 1 enabled Intel MT Mobile Connector for my cable internet connection and 10 disabled wireless network connection.
    I can delete all of them but I am not sure it solved the problem.
    What info do you like to know after ipcongig / all

    Thanks

    I want to see the entire output as I requested. Also, exactly WHAT devices are showing up in Network adapters? I need to know that, which is also why I asked for that information.

    ipconfig /all shows only details for Ethernet adapter local area connection. There is no one wireless adapter presented not here, not under device manager and antenna indicator is not flashing, however when I tested it in BIOS antenna was flashing and wireless adapter (unfortunately it did not show adapter name) was connected to access point. After retrying to install drivers from Lenovo, rebooting I got only to the point when it shows Network controller with ? under other devices.

    That Network controller in Other Devices is probably the wireless adapter with missing drivers. You need to load the correct drivers for the wireless to get it back in the game.
