    Internet Connection Lost on Restart


    I posted the message below on another popular Windows 7 forum two weeks ago. So far the message has been viewed 267 times, yet not a single reply proposing a solution has been posted. I am hoping that there may be an expert on this forum who can shed some light on the problem and hopefully propose a solution.

    =====================

    For several months I have lost my Internet connection whenever I restart my Windows 7 Home Premium computer. Fortunately I use the sleep function at night and only restart two or three times a week. I have found a way to connect to the Internet following a restart that works almost every time, but it is a nuisance to go through the steps. I am hoping that a description of the procedure I use will prompt someone to suggest a permanent fix to the problem so the computer will come up with an Internet connection following a restart.

    After a restart and no Internet connection the Network and Sharing Center shows two networks when there should be only one. They are:

    Network - Home network - Connection: Mynetworkname Broadband

    Unidentified network - Public network - Connection: Mynetworkname Broadband

    I have no idea why the second network is present, but it is probably at the heart of the problem. My correction procedure is the following:

    Click Mynetworkname Broadband and then click Disable.

    Both of the networks described above disappear, and the message "You are currently not connected to any networks." appears. This statement is accurate at this point.

    Next I click Troubleshoot problems and Internet connections. A message says, "Troubleshoot and help prevent computer problems." I click Next and then Troubleshoot my connection to the Internet.

    I am told, "The Mynetworkname Broadband adapter is disabled" (which of course it is). I click Try these repairs as an administrator, and Resolving problems is displayed.

    The word Fixed appears after the statement "The Mynetworkname Broadband adapter is disabled", and I click Close the troubleshooter.

    At this point the Internet connection becomes operational, and the Network and Sharing Center shows only one network - the first one shown above and not the unidentified network.

    Any ideas or advice?

    according to your listed specs--this is a Vista machine?

    the 'unidentified' network may be referring to a 'wireless' setup--are you using a router? are you setup wireless?

    an easier way to accomplish the procedure that you described is--simply open 'device manager' disable network adapter--then 'enable' it--which should make it function


    it would make it easier to assist you if you describe your connection--for example:
    modem>router>computer(laptop or desktop?)>wireless enabled? etc

    Thanks for your response, tman69. I will try to provide the info you requested. Although my desktop PC was originally delivered with Vista, I upgraded it to Windows 7 Home Premium more than three years ago. It is only in the last 2 or 3 months that the problem I describe first appeared.

    The computer is connected by a cable to a Cisco router, which in turn is connected to a Motorola modem. The computer does not have a wireless adapter. The router provides a home network to one other almost identical desktop computer, as well as to an occasional laptop, an iPhone, an iPad, an Android phone, and an Android tablet.

    The next time I have the problem I will use your Device Manager procedure.

    Just restarted the PC for the first time since seeing your message. No Internet access following restart. Used your disable/enable technique and it worked just fine. Thanks! Still don't know why the basic problem occurs.

    it's good to hear that the 'simpler' solution works for you.

    as far as the basic problem...

    you said "The router provides a home network to one other almost identical desktop computer"

    does the same situation (no network connection) happen with the other computer?

    Interesting that you should ask. The other computer (connected wirelessly) is my wife's. It experiences different problems. Every day or two it loses the Internet connection at random times, not when it is restarted. When its Internet connection is off, mine is still on. The disable/enable trick that fixes my connection does not fix hers. The fix for her problem (at least the only one I've found so far) is to power cycle the router - off for about 10 seconds and then back on. This of course also kills my Internet connection briefly, but then both computers come back onto the Internet.

    the 'mystery' (Unidentified network - Public network) network you're experiencing--is your wife's 'wireless' connected machine.
    Check to see if her wireless adapter is set to 'sleep/hibernate' (it shouldn't be, as this 'could' be the cause of the problem). Also check to see her 'power options'. see attached pic
    I believe you actually have 'two' networks--one wired and one wireless.
    (make sure the wireless is 'secured' with a password).
    note to properly power cycle:
    Power off everything (unplug modem).
    Wait several minutes.
    Power up modem.
    Wait for modem to sync with ISP (a minute or so).
    Power up router.
    Wait for router to sync with modem.
    Power up computer(s)

    All settings are as recommended. Wireless network is secured with WPA.

    I don't believe there are two different networks. Both my PC and my wife's show up as members of the same network in both the Windows 7 network diagram and the one produced by the Network Magic program.

    These computers and the network have been operating for more than three years, and these problems have surfaced in the last couple of months.

    Maybe it's time to upgrade to Windows 8?

    The unidentified network problem is no doubt the cause of network connection problem, until that problem is taken care of this problem will persist.

    Do you have iTunes or Adobe CS3 installed on this system?

    Which anti virus software are you running?

    Can you post the ipconfig/all so we can see any other potential problems.

    I have a good idea of what this problem is but I need to see the ipconfig to make sure and the other questions are important.

    I will try to provide all requested information.

    iTunes is installed on my wife's computer (she has an iPad) but not on mine.

    Photoshop Elements 8 (not CS3) is installed on my wife's computer but not on mine.

    We are both running Trend Micro Titanium Maximum Security 2012 software.
