Windows 7 - no available network connection.

I have a Gigabyte motherboard with the latest drivers and 2 GB Ethernet ports. When I plug in an ethernet cable, I am able to get an IP address, browse the Internet and selectively access the resources on my local network. I can even show a network card (although it says, falsely, that I don't have an internet connection)

However, if I try to configure all aspects of my network connection, I get the error there is no available network connection. I'm able to join a working group, but still no available network connection. Other users can access the files that I've shared, but still no available network connection.

I even went out and bought a new PCI NETWORK card and installed to see if there was a problem with my built-in ethernet ports. No help.

And please, before leave you any response like, "well, if you can access the network, what is the problem? I'm not asking for help assess whether or not I have a problem with my network on this PC Setup, I am simply asking for help the issue stating that I don't have a network connection.

It turns out that multiple applications use Windows 7 network connections and when he says that there are no available networks, these applications do not work.

Please let me know where to go from here. I appreciate all genuine advice; Thank you in advance.

Bandit, the best of the two PC's Go two network cards on the motherboard. I tried both interfaces without change in the results. I disabled an and tried on the other. No results. I swapped the port disabled, no help. I've disabled the two built-in network interface cards and installed a new wired Ethernet NIC - same questions. I installed a wireless PCI-Express - same question card. I have installed many adapters Wireless USB... no change.

I rebuilt my IPV6 stack more than one dozen times based on Technet article after article. I even signed up for two providers to Tunnel IPv6 thinking that a fully enabled IPv6 stack would probably address some of the problem... no luck.
And while it seems that there should not be a problem given that I have LAN and internet access on my PC and other devices, the problem comes at odd times. iTunes (it is true that the garbage, btw) refuses to interface with other computers for home sharing. My Samsung TV can browse all shared media PCs with the exception of a single PC that started all this.
And remove the PC from the network does not help. It's as if I'm stuck in limbo, because I can access the homegroup PC provider. Whatever the cause, it is unreasonable. And as I look through these forums, I find more and more people having the same problem - it's just that most people don't care as long as they can go to youTube and check their e-mail.
Thanks again for your support and feel free to offer other suggestions. My next step is going to be a new installation on a new drive on both computers of problem to see if it is actually a hardware problem or a configuration problem. I'm willing to bet that it is software, not hardware... but we'll see... I'll report my findings...

  • G6-2231dx Pavilion: Pavilion g6-2231dx and Windows 10 lack of network connections

    Then...  Where are the pilots 10 compatible of Windows for the g6-2231dx Pavilion?  I know that this OS was just launched yesterday, but an excerpt from the developer is available for some time now and any reasonable person would expect a company as big as HP now have their stuff ready for this deployment.

    The latest version of the operating system available on the menu drop-down page downloads & drivers of the g6 is Windows 8.1.  While the Realtek PCIe FE ethernet family and drivers Ralink RT3290 WLAN view and proclaim that they are in perfect working order through the Device Manager, or a connection to the local area network or WLAN connection appear when I opened the section "Manage maps" of the network and sharing Center.

    I've tried so far to solve the problem of the measures:

    Searched in vain for the site of HP compatible drivers, or at least an explanation of why it is not all the drivers available for Windows 10 on my device. By-the-way, there are a lot of dead links on your site.  Did the same to sites Web of Realtek and Mediatek without any result.  Googling has not helped much either.

    Downloaded and installed the latest drivers Windows 8.1, after uninstall of each device (as well as the removal of their files in the system directory) of the Device Manager with a reboot between the two attempts, since the HP website as well as websites of card manufacturers.  No results.

    Updated drivers for each devices via Device Manager and manually that it points to the directory where I extracted the drivers. No results.

    Disabled features, that I had to do to solve the problems with adapters flakey on the latest operating system from Windows to save energy.  No results.

    Rolled back drivers through Device Manager.  No results.

    Uninstalled devices again, tried and then install the drivers in compatibility mode. No results.

    Tried to install the Realtek drivers which claimed to be compatible with Windows 10 that I acquired through the Lenovo Web site. No post no installed errors, but network connections still do not come under the list, while continued to report as work awesomely by Device Manager!

    Editing a registry string by a suggestion in another forum support, but for developers of Windows 10 preview who proposed to change the string of 'dela Jacques = 7' where it was previously set at 5, in my situation.  No results.

    The state icon of connection in the system status bar always has a big, big, red X through it, when I left click on the icon, if waiting to see at least a list of available wireless networks, it is completely empty, with the exception of the option to turn on or turn off the airplane mode (Yes, I made sure it's off).

    It is quite frustrating and I know this isn't quite exclusive fault of HP/Realtek/Mediatek and I'm sure Microsoft has a big had to play in a no-so-finished product, but geeze!  Any help out there?

    MInutes after posting here, I found a solution to the problem of another Web site. This solution is relevant to those who have had a VPN software installed on their system during the upgrade of Windows 10. It may be worth a try, even if you don't have a VPN software installed prior to the upgrade. I followed the instructions below and after you remove both registry key and uninstall the DNI_DNE, the network adpaters Protocol (ethernet or wireless) immediately turned on and connected automatically without having to restart the computer.

    If you have unsupported software VPN installed on Windows 8.1 when you upgrade, you may experience this problem.  We are currently working on a fix.  To check if that's causing your problem of networking:

    1. Click the Start button, then click command prompt (Admin).

    2. Type the following command in the window and press ENTER:

    3. netcfg - s n

  • This will display a list of network protocols, drivers, and services.  Check if DNI_DNE is listed in the output.  If this is the case, this problem applies to you.

  • If DNI_DNE is present in the same command prompt window, type the following commands to solve the problem:

    Reg delete HKCR\CLSID\ {988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f

    netcfg - v u dni_dne

  • If you receive the error 0 x 80004002 after execution of this correction, or the registry key has not been removed or the key that should be deleted is slightly different.  Open Regedit and navigate to the key: HKEY_CLASSES_ROOT\CLSID\ {988248f3-a1ad-49bf-9170-676cbbc36ba3}.  Delete it if it still exists. If this is not present and you still not received this error, just reply to the post.  We may contact you to help identify the cause of this error.

  • Slight modification of my original posting. Please remove the ' / going ' from the code as it is does not delete the subkeys, only values. So, if you have dni_dne and tried this fix with an error result, please try this again with the following change in the original post:

    reg delete HKCR\CLSID\ {988248f3-a1ad-49bf-9170-676cbbc36ba3} /f

  • Errors in Windows 7 with Windows Help and Support, network connection, and the system restore

    I have a HP Pavilion dv6 (4 years), sometimes overheated with heavy use. Normally I can cool, restart and wear. However, my laptop just overheated and closes, and this time I encounter all sorts of problems.
    First of all, after the reboot, I noticed that the system does not automatically connected to my Wi - Fi (it does not even recognize the available network).
    Secondly, in attempting to fix the network problem, I clicked on the link "Troubleshooting", only to receive the following error message "an unexpected error has occurred. ID of Package cannot continue the Troubleshooting Wizard": unknown path: C:\Windows\diagnostics\system\networking error Code: 0x8007045A

    Third, because troubleshooting did not work, I thought I'd try the help and Support Windows to search for answers. However, when I opened it, I received the following message: "Windows Help and support has encountered a problem. You might be able to solve the problem by restarting Windows Help and Support. If the problem persists, proceed as follows: 1. search the online help on the Windows website.  2. contact your manufacturer of computers or Microsoft Support for assistance. There could be a problem with one or more Windows system files or folders on your computer. "Because I could not connect to the internet, these suggestions and links were useless.

    Fourthly, as I failed to locate the problem, I tried a system restore. However, after he appeared to run (took about 30 min) and restarted Windows, the following message appeared: "system restore was not entirely successful. The system files and settings on your computer did not change. Details: System Restore could not access a file. This is probably because an antivirus program is running on the computer. Temporarily disable your antivirus and restart System Restore. An unspecified error occurred during system restore. (0x80070005)
    You can try the system restore again and choose a different restore point. If you continue to see this error, you can try an advanced recovery method. For more information, see what is recovery? "I have disable my antivirus (AVG), tried and received the same error message.

    Short physically all my backup files and restore to factory settings, I think I've exhausted what I can do.

    * EDIT * after scouring the site, I found a suggestion to run the tool via the command prompt System File Checker (see thread here: http://answers.microsoft.com/en-us/windows/forum/windows_7-performance/no-internet-connection-on-this-computer-after/83fb22c9-712e-467d-9a68-f8d52dde9bcb), which I did and found some corrupted files. The following response appears: "Windows Resource Protection found corrupt files and repaired successfully details can be found in the CBS.log newspaper... File system changes will take effect after the next reboot. "After restarting, the internet connection problem seems to have been resolved. Service work. and Windows Help and Support also works! I hope it helps someone else!

    Hi Lorenacadi,

    Thanks for sharing of the resolution. Your efforts and patience are highly appreciated.

    In addition to the emission of heat:

    Two things inside the laptop generate heat - power (in the place where the power cord plugged in) and the processor.  The CPU has a heater and a fan to help disperse the heat and keep the CPU at a reasonable temperature.  Hot air is sent on the vents, and air at room temperature between in other events.
    What happens generally is dust forms near the vents, near the Airways within the laptop computer which lead to the mouths and on the CPU fan itself.  All these sources of dust cause airflow slow down, so that the hot air lingers and gets even hotter.  To resolve this problem, you will need to take the laptop apart and 'very good' to clean the dust and the CPU fan.

    Another potential source of heat which would be composed of dust problem might be software related.  More 'work' the CPU must do the most energy is needed and therefore more heat is released.

  • Firefox cannot connect to a local server subdomain if no available network connection.

    Hello

    I have a laptop that is configured as a local server using Apache. On this, I use "localhost" as the domain and have several subdomains.
    Now, if I have no network connection (to any other device) available on this laptop, and then with Firefox I am only able to access the domain 'localhost', but none of the subdomains and get a "Server not found" error on these. If I have a network connection, I can access the domain and subdomains with no problems.

  • Windows 7 has no network connection after merger put level 4.1

    My Fusion environment with Windows XP and Windows 7 has known chronic Mac OS X virtual machines balls Beach, especially when two VMS are active.  When Check for Updates showed 4.1 has been improving the performance offered and included, I went ahead with the upgrade.

    Fusion 4.1 itself and Windows XP seems to work very well.  Windows 7 looks OK, except there is no network connection.  Windows 7 network troubleshooting (not realizing it runs under merger) reports that the Ethernet cable is not connected.

    I tried the simple fixes I know:

    1. Difference Fusion Windows XP and Win7 settings - network adapter network > NAT settings look identical.
    2. Restart Windows 7.
    3. Restart the Fusion 4 and restore Windows 7.

    I searched this community and the knowledge base to find clues, but positions see Fusion 3 or take the skills that are beyond me in troubleshooting Windows.

    What are my next steps?

    Hello

    Have you tried restarting your Mac, or at least unlog and relog? I had the same problem and do so resolved.

    The problem seems to be (on the side mac) that the extension of the kernel named "vmioplug" of the old version of VMWare Fusion could not be unloaded. Thus, a new could not be charged and that avoided networking to work properly...

    I got the following error in /var/log/system.log launching VMWare Fusion 4.1:

    19 Nov 23:37:48 Macbookabenua com.apple.kextd [13]: unable to load the Applications/Utilities/VMware Fusion.app/Contents/Library/kexts/vmioplug.kext - a different version is already loaded.

    So I tried to unload this old extension manually (via: sudo kextunload ' / Applications/Utilities/VMware Fusion.app/Contents/Library/kexts/vmioplug.kext'), but this did not help. Really, the extension could not be unloaded.

    But unlogging apparently unlocked something and allowed me to unload the extension core.

    While using Apple TV and pictures, I get a message that says don't: no available network connection.  I check other programs and they have an available network connection and all is well.  This happens intermittently, but once it happens, you will need to restart the apple tv several times and I hope that solves the problem.  I use icloud photo library and I am trying to access my photos.  Is this a known issue?

    This could be one of those cases where the message is just a generic "connection failed" message. So he doesn't mean what he says, just that it cannot connect to the server iCloud.

    Together there is automatic DNS in your network ATV settings?

    Are you sure that there is no interference from WiFi? If there is no interference, a reboot should be enough.

    When photos fails, you can use another application that uses the internet?
