    Local Area Connection doesn't have a valid IP config


    Hello,
    There have been already few threads open for this topic not only on this forum but on different ones around the world, however the problem is still not solved, thus I decided to open a new topic and solve this problem once and for all.
    Here is the problem: I cannot connect to my wired network, it is stuck for a while at 'identifying' and then it says: " "Local Area Connection 2" doesn't have a valid IP configuration Not fixed "
    I have tried restarting the laptop, turning off/on the router and modem, manually assigning ip address, disabling/enabling network adapter, disabling/enabling TCP/IPv6, I have tried basically everything - all the suggestions that I have found on different forums but nothing helps!
    The weird thing is that I am connected to the same network via my wireless.
    Finally the solution to the problem:
    1.Right Clicked Local Area Connection
    2.Clicked Configure
    3.Advanced Tab
    4.Highlighted Network Address and changed value by entering random 12 alphanumeric characters (i used 02EF22FD2310 from the top of my mind)
    5. Click OK
    Thanks to : Possible solution for unidentified network access

    Can't find Local Area Connection to right click


    Please read what I wrote in http://pocketpccentral.net/blog/2009...blem-resolved/ I was finally able to fix the problem. The fix involved updating the Windows 7 Network Adapter’s IPv4 setting, but not the first few times I tried it. At first, every time I re-booted the update would disappear. Then, I spoke with someone else and they asked me if I had reset my router. I have three desktops plugged into a Linksys Wireless Router and I had updated the firmware on the router the night before all of this happened. The only computer that still connected to the Internet was the one I used to update the firmware. I used it to research the problem. I had tried several of the fixes I found. I even applied the "fix-it" that Microsoft offered to reset the log. I could not get that to work when I did it myself, even though I am the administrator, it kept on responding that I needed to be at the administrator level to perform the function.

    Then based on what my friend had said, I unplugged my router for a couple of minutes, from the power supply, plugged it back in, then went to the network and sharing center. I set up a home connection. I then had a home and unidentified network. I tried everything I could to delete that public network connection. Nothing worked. I kept getting a message that it could not be deleted because it was in use. My friend said it did not matter, to just leave the unidentified network. But it did matter.... I re-booted and the home network Internet connection disappeared! I was back to two networks and no Internet. I clicked on the Home Network Connection, disabled it, then enabled it. It worked, again, and I had Internet. I was about ready to settle for that and just reset after a reboot, when I decided to check the Network Adapter’s IPv4 settings. What I found were two addresses in the Default gateways IP addressess. One was a 169… the other was a 192….. address. I deleted the 169 address and the public network disappeared! I rebooted and all was well. It is still working this morning.

    When you click 'change adapter settings' it should open 'Network Connections' folder. There you will see network connections, for example I have 2: 1 is 'Local Area Connection' and another is 'Wireless Network Connection'. Right click the one that you are using, if it is wired connection then you should right-click 'Local Area Connection' and from the options at the bottom you will find 'Properties'
    Briefly-> It is in Control Panel->Network and Internet->Network Connections
    Good Luck!

    Hi guys!

    I have had the same problem for a few days now, and have searched numerous forums and gone through hell and high water to fix it. nothing helped until I found the ultimate solution that will help everyone:

    CALL YOUR ISP, TELL THEM WHAT HAPPENED AND THEY CAN CONFIGURE A NEW IP ADDRESS FOR YOUR CONNECTION. IT ONLY TAKES ABOUT HALF AN HOUR.

    During this time you must keep your router/modem turned off, and after the ISP has fixed the problem (in my case it took half an hour) you must restart your machine with the router/modem on and connected. From then on it should be like nothing ever happened.

    Just for the fun of it, here's a list of things I have tried without results:

    release/renew ipconfig
    restarting modem/router and computer about a zillion times
    changing LAN card
    creating a static IP
    resetting winsock in command prompt
    reinstalling Win7
    reinstalling XP (I had a dual boot and I did both, losing all installations)
    manually entering IP address
    disabling/enabling local area connection
    plugging and unplugging LAN cable
    uninstalling and reinstalling LAN card driver
    resetting modem/router using the reset button

    And after all this, all it took was just a phone call.
    This is because your ISP is THE ONLY authority when it comes to configuring your IP address. In this case, it can only be done from the outside. this is also the reason why Microsoft didn't announce any patches or fixes for this problem, because it is not their problem and responsibility.

    Only one question remains, WHY is this happening? Noone has been able to answer this, and I have read tons of forum posts about it. Maybe even the guys that made Windows 7 don't know it.

    I am going to copy this post on several other forums because I have seen the trouble that people are having with this problem.

    If you find out why this is happening, please post it here.
