    have a Toshiba laptop with windows vista home.
    I use wired Network Connection to my Internet provider router.
    My IP and gateway is a PUBLIC IP’s.
    Everything works fine, network card, router, except Vista.
    I’m not being able to ping router, as well as any IP beyond, only Localhost
    and my IP.
    Disabling Firewall not solved this problem.
    Here is strangest thing - when I push “View full mapâ€, and while Network Map
    discovering, I have worked Internet Connection, gateway become pingable, and
    I can open any web site!!! But when Network Map shows up - connection
    dropped, gateway become unpingable. In case, it draw correct Network Map.
    How I can fix it?
    What exactly started then I push “View full map� Which service or process?
    How in “unblock†TCP traffic? How to “unblock†it constantly?

    Please HELP!!! I haven’t any Net at home :(

    P.S. I have tested this Laptop’s wired Network Connection in other PRIVATE
    network, and I not found such issues! May be here is a problem?

  2. Hi
    From the way you describe your Internet connection it is Not clear what is
    that you have there.
    If you have a Router,then your IP and gateway should be private (the
    192.168.x.x) type.
    If you connected directly to a Modem you might have authentication problem.
    In general,
    Give a better description of the Internet connection ISP and hardware that
    is involved.

    Hi Jack!

    Thanx for reply!

    No, there is no modem in my environment, just router (gateway).
    Here is my IP configuration

    IP –
    Mask –
    GW – (Internet provider hardware)

    And 2 DNS of course, not remember (I’m in office now)
    So GW is not pingable, in become pingable (and full access to internet
    become available) only when network map drawing.

    This is explain my PUBLIC IP (accessible from Internet)

  4. Hi
    When two computers share one connection there is need of a Router.
    Router then provides a private IP to each computer.
    Your IP ( does not indicate Routing. Your XP works OK as
    single computer once you add the Vista it can not work with the same IP.
    Maybe this can Help.
    The content of the following links will provide you with a basic tutorial
    about Sharing Internet connection; it is short and to the point. The pages
    were written by me ages ago. Ignore the prices, and the specific choice of
    hardware, stick with the principles they are still the same.
    Basic Options for Internet Connection Sharing -
    Hubs, routers, switches, DSL, LANs, WANs...? -
    What do I need for wireless networking? -
    The whole thing should look like this,

    Hi Jack

    My PC was replaced by Laptop, so I'm using only one computer now.
    Also, I have only one UTP cable with no HUB at home.
    This cable goes directly to provider hardware.
    So, I have only one Ethernet port, only one link and only one IP and no any
    sharing with other PC (other PC does not exist in my environment) .

    Once again, all my IP config on VISTA is correct, as well as it was on XP
    (now XP unavailable anymore). But, on XP (on other PC which gone already) it
    works fine, now on VISTA it doesn’t work. XP was replaced by VISTA, at XP
    internet connection works, at VISTA not. IP configuration at XP and now at
    Vista the same. There is no physical address (MAC) filtering/authorizing at
    my environment (I can use any net card, I can replace my net card with no

    Thanks for links, but it’s not about my problem.

    My problem with no internet connection on Vista with this IP configuration.
    I have red cross on network-internet link, my GW is unpingable from VISTA
    (it was pingable from XP, when old PC was available)
    If I push “Network full map†GW become pingable and red cross gone, but when
    “Network Map†showed up Internet Connection blocked again and red cross
