    Hi

    I have a Samsung laptop running windows 7 home premium.
    Although I have always been able to connect wirelessly to the internet, as of a week ago, I cannot connect to internet.
    It does connect to the router but not to internet.
    The router is fine as I do connect no problem with another laptop.
    I notice that in profile network, I have Public ( current profile) and cannot change it to Home.
    Not sure if this is the cause,
    Please help

    Thanks

    Jadan

    What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, kaspersky or Mcafee or any free security suites like zonealarm, AVG , Webroot etc

    would you post the following tests when the internet is working OK, and then repeat ALL the tests when the internet disconnects.
    Make sure you also indicate on the reply which tests are for what condition.

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

    Post back the results in a reply here
    right click in the command prompt box
    select all
    enter

    if you see on the results a
    "general Failure"

    those results show a good connection to the internet

    I assume you copied the results taken from the PC that does not work onto the working PC correct

    Thank you Wayne,
    I have now noticed that the laptop is connected to internet , although the icon on the bottom right task bar indicates the network is not connected.
    Also when I open the Network and Sharing Center, it also says " you are currently not connected to any networks" and when I click on "see full map" an error comes up saying: " Windows cannot create the network map because the network's location type is Public."
    I have tried changing the network profile from Public to Home, but there is no way I can change it.
    Any ideas on this issue?
    Thanks again

    remove the wireless profile

    reconnect to the network - enter the key

    it should ask you what type of network - Home/work/public

    How to remove Wireless Profiles - for Vista and Windows 7
    http://uk.tp-link.com/article/?id=281
    http://www.home-network-help.com/delete-wireless-network.html
    - Vista/Windows7:
    - delete the wireless profiles
    Start> control Panel> classic view> network and sharing center> manage wireless networks

    Delete the profiles
    you will then have to enter the wireless security key for any networks you connect to - so make sure you know the correct password , and not using an incorrect password at all
