    Hi guys please help me urgently.
    I have been facing a very weired problem with my laptops.
    I got a office brand new laptop recently which i brought home directly.the weired problem is that whenever i use to connect this laptop with my home wifi,the home wifi service gets shut down and all other friends mobile phones and laptops does not get wifi signals until i restart the modem/ router.so there is definitely something in this laptop which is causing model or router to disable service.
    I thought it an mysterious issue in my dell laptop and asked office to give me a new laptop which i got today and to my unfortunate luck i am facing the same issue again.
    So both are new laptops without any virus or hardware software issue.

    But infact there are other 2 laptops which my friend use and we never face any problem like this but the soon i open my laptop internet goes down for all.

    can we see an ipconfig /all from the work laptop please
    ------------------------------------------------------------------------
    ipconfig /all

    We would like to see the results from an ipconfig /all - post back the results in a reply here.

    If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post the results in a reply here.
    Save the file to a USB flash drive or other removable media. Plug it into the working computer with internet access and copy the file and paste here.

    If you do not have another PC - do you have a phone connected to the internet - can you photograph the result and post the image in a reply
    Note: you will see entries named Tunnel adapter Teredo Tunneling Pseudo-Interface: we dont need to see that information - JUST the information above those entries

    For Windows 8
    To open a Cmd Prompt or an Administrator Cmd prompt from the Desktop.
    http://www.bleepingcomputer.com/tutorials/open-an-elevated-command-prompt-in-windows-8/
    Use Win + X and choose Command Prompt or Command Prompt (Admin) from the list.​

    For windows version, XP, Vista, W7
    Hold the Windows key and press R

    Now type CMD

    Now press Enter to open a command prompt box (A new dialogue box - black with white font, will appear on screen ):​

    In the command prompt window that opens, 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 > network.txt & network.txt

    It will export the results into notepad and then automatically open the notepad and display on your screen.

    Now all you need to do is copy and paste those results into a reply here
    to do that:
    From the notepad menu - choose Edit - Select all
    all the text will now be highlighted
    Next
    From the notepad menu - choose Edit - Copy

    Now go back to the forum - goto the reply and then right click in the reply box and paste the results.
    The results from the notepad should now appear in the forum reply.

    The ipconfig which i pasted is from the same laptop but i am connecting with LAN right now as there is no issue with LAN.
    Issue is seen only when wifi is turned ON on laptop.

    so it does always disconnect
    only sometimes
    AND
    it only disconnects if the work laptop is connected

    the ipconfig /all looks OK
