    I am having issues with my laptop. Before my computer was connection to the wifi at home just fine. This afternoon the cable company changed out router/modem combo and now my computer won't connect to the internet unless it is connected via Ethernet cable. Please help

    can you post an ipconfig /all

    are you running windows vista?

    have you entered the new wireless key for the new router ?

    ------------------------------------------------------------------------
    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.

    To add to Wayne's question.

    If the modem/router combo was replaced, your SSID and security key was probably changed and should've been given to you by the cable technician.

    You also should've had your laptop turned on and made sure its wireless connection was working okay before he left.

    If Wayne's instructions don't fix the problem, call your ISP tech support number and advise them of the problem.

    They may be able to talk you through and fix the problem without sending a cable technician back to your home.
