    Internet Connection Drops Constantly

    Hello, I'm experiencing frequent problems with my Internet Connection. My
    computer is connected to the Internet through a Motorola Surfboard modem from
    Charter Communications. My computer will randomly disconnect from the
    Internet around every hour. The modem still says that it is connected as will
    my computer if I go to the Network and Sharing Center. Even though the
    computer says that it is connected, no program can access the Internet.
    Anytime I open a Firefox it will usually say "Cannot Find Server" and
    Internet Explorer will just say that it cannot display the webpage. Sometimes
    I will get popups from Windows (I believe, though it could be FireFox) trying
    to connect to a broadband connection. It never works, though, and it asks for
    a password and username. I do not have one, though. I have not set up any
    sort of password for accessing any Internet connection on my computer. When I
    first upgraded computers all I had to do was plug in the cable modem and
    Vista automatically connected. It was perfect and I had no issues for quite a
    while. The connection dropped on day and Charter walked me through a process
    which reset my cable modem and got me back online. Ever since then I have
    been having this issue where my computer randomly loses it's connection. I
    was not able to get online for about an hour today. I did a System Restore to
    see if anyone had possibly done something, but the problem presisted. I came
    back later and now everything is running relatively fine!? It's like the
    computer has a mind of it's own. Any help would be greatly appreciated. I
    called Charter and it is supposedly normal for the connection to drop from
    time to time. They suggest unplugging the modem for 30 seconds, but that does
    nothing for my issue and their support pretty much ends there. Thanks.

    first, you should get yourself a router to put between your cable
    modem and your computer. it is much safer.

    second, if you have unrecognized password prompts, you should scan
    for malware. start here http://aumha.org/a/quickfix.htm

    lastly, you have provided no info about your connection. please post
    the text output of ipconfig /all

    Thanks for the response. I've run Adaware, Spybot, and AVg AntiSpyware. None
    of these found anything, except Adaware which found some tracking cookies.
    The password window is popping up in response to my browsers trying to
    connect to the Internet. All of my programs know when my connection is gone,
    but Network Sharing Center and the actual system seems to think it's working
    fine. I'd post a screenshot, but I'm not getting the message at the moment
    since my Internet is working properly. Here is the information from ipconfig:

    I don't know what Charter had you do that day. Can you go back to a
    system restore before they had you make changes?

    Then, unbind IPv6:

    You really should get a router to put between your computer and the
    cable modem for safety.

    I wish I could, but my system only has restore pints dating back to the
    installation of Service Pack 1 for Vista. Charter rest my connection, but
    that didn't work. They asked for my ip address and that's about all I can
    specifically remember. It happened quite a while ago, but the issue has
    gotten worse so I'm seeking help from other places. How will a router between
    my computer offer security? I don't know that much about routers, but
    wouldn't it open up possibilities of others using my connection? Thanks for
    the help .

    most modern routers have a hardware firewall and all offer the
    protection of NAT. you can disable the wireless radio in some
    wireless routers (this is not the same as disabling SSID broadcast).
    and you leave the router and your cable modem turned on 24/7 so you
    don't lose the IP from your ISP.

    don't know if this will improve the situation, but it might.

    did you unbind IPv6?

    I disabled few services which I thought were unnecessary, as I am not using
    any Symantec products I disabled "Symantec Lic Net Connect Service" then my
    Internet connection started dropping very often. I was thinking it was SP1
    but when I changed Symantec Lic Net Connect Service back to manual everything
    is fine. I hope this will be helpful to someone and suggest not to throw
    money away on new equipment before trying something simple.

    Re: Internet Connection Drops Constantly

    the fact that you have this service on your computer indicates that
    Norton/Symantec products were installed at one point. If you have
    disabled but not uninstalled a Norton product, almost anything can
    happen. Norton acknowledges that they have issues with their
    programs. See
    http://service1.symantec.com/SUPPORT...nsf&view=docid
    as an example.

    your issue seems completely different. You should not need this
    service running if you are not using Norton products.

    Re: Internet Connection Drops Constantly

    Regarding those logon prompts, I think probably you have 'dial whenever a
    connection is not present' enabled in your Internet Explorer connection
    settings. That could be correct if your modem is set to log off when there
    is no keyboard activity for a period of time, but if the internet connection
    is supposedly 'always on' then you should change the IE setting to "never
    dial" a connection. The logon prompts should stop happening after that.

    If you have a 3rd party firewall on your computer it could be the source of
    your intermittent connection problems. Try disabling it or uninstall it and
    use the Vista firewall instead.
