Network Adapter Disabled

I have a Qosmio X305, Vista. The Wireless adapter is disabled.  Connectivity Doctor says to enable adapter press Fn+F8 but there is no response either in Connection Doctor or outside of application.  There doesn't' seem to be any other method to enable adapter.  Does anyone have any hints or tips?
Solved!
Go to Solution.

Try reinstalling the driver. If the first one doesn't work out, try the second.

  • Z77A-GD65 - Intel Network Adapter disabled when coming out of sleep mode

    Just put together a new system with a Z77A-GD65 motherboard, Core i7 3770, and Corsair Vengeance RAM.
    Installed the Windows 8 RTM (final release) version, which installs flawlessly and works fine. (Yes, I have an early license to Win8).
    Here's the problem.  If the system goes to sleep, when it comes back out of sleep mode, the Intel Network Adapter stops working. (Hence, all network and internet connectivity is off). This is evident by the Network Status icon in the explorer task tray showing a red "X".  Any attempt to run the troubleshooter results in the message "The Intel 82579LM Gigabit Network Connection adapters is experiencing driver or hardware problems".  Screenshots and log files can be found on my Skydrive here: h t t p : //sdrv.ms/NVBatL
    The driver version of the NIC, is what Windows installed during setup, is from Intel, version 12.0.150.0 dated 2/29/2012. (It was installed with Windows 8 by default).
    Rebooting the machine fixes the problem.  For now, setting the Windows power settings to never sleep is my current workaround. I tried downloading and installing some software and driver packages from Intel that I thought might update the driver, but it did not work.
    I am assuming this issue will not be present if I put on Windows 7, but that's what I was really hoping to avoid.  Suggestions?  Newer Intel driver available?

    Quote
    I don't know why you think this workaround "defeats the the object of having power saving features".  That might be a fair point if this was a laptop relying on battery charge.  But "sleep" doesn't mean "zero power".  It means just enough power to keep the memory alive and some LEDs blinking.
    In the case of a desktop build, keeping the LAN adapter awake is a non-issue.  Several hundred watts of power are being consumed when the PC is on. When it goes to sleep, that power usage drops down just a handful of watts.  If the workaround means having to dedicate an extra watt of power to the LAN adapter, then so be it.
    I am not trying to discourage what you did. I have found many a work around to niggly bugs over the years. All I am trying to state is that this bug should be fixed, i.e. the LAN should wake up together with the PC. At the moment it works for you, which is great, and you reported it. Nothing more you can do.
    As for the power saving. Yes of course we are talking about negligible consumption here, but the principle is that all these new machines have to comply with EuP2013 which dictates a maximum power usage for the total system when being in a sleep state. This can obviously not be achieved when one has to keep components powered because of a bug. 
    I would be interested to know what ME firmware version you have on your machine. I myself have had irritating intermittent issues with the Intel LAN on the same board as you in terms of the LAN remaining dead after start up whenever I change HW or do firmware updates. It then takes a restart to get the LAN active again.
    Intel has released two IME updates over the last month and there is a recent update for the Ethernet controller as well. I updated both and am monitoring. Since the update I have not had any further issues, but its still early days and I am reluctant to say it solved the issue.

  • Download connections doesn't close after I cancel the download, it keep like I am download and only close when I disable the network adapter or reset the router or the firewall

    download connections doesn't close after I cancel the download, it keep like I am downloading and only close when I disable the network adapter or reset the router or the firewall.
    I use pfsense as my firewall and see the traffic not reseting to zero when I cancel download.
    Also, IE doesn't have this problem. When I cancel the download the traffic drops to zero.

    And this problem seems to be systemwide. Since I created a new user and under which problem still exists.
    Hope apple will look into it

  • Upgrading from iTunes 10.4.1.10 to 10.5.3 on Windows 7 - network adapter is disabled

    Hi all,
    I tried upgrading to iTunes10.5 on a Windows 7 HP Elitebook 2530p and the result is that my Wi-Fi and Ethernet network adapters become disabled.  In fact, they are effectively deinstalled - they simply disappear and I am unable to reinstall or use the Windows hardware installer to automatically find them and reinstall.  I had to deinstall the iTunes upgrade and then restore my system back using the pre-install restore point- and the network adapter magically reappear! Noticed this issue seemed to be a known problem and discussed at length on these boards.  Have not tried this update since ~Nov so perhaps it has now been corrected, but I didn't want to risk attempting again only to have to back out and waste more time.  Can anyone confirm that the current 10.5.3 update fixes this network adapter problem on Windows 7 32-bit? Many thanks, Mark

    I came upon the solution in another discussion thread.  The solution is to simply wait 8 to 10 minutes on the language selection dialog box allow the install program time to find my OS 10.4.1.1..  I then clicked on "Continue" and the install proceeded without any problems.  I know am running Leopard OS 10.5.8., So far with no cliches..."knock on wood".  Thanks to all who responded to my original question.

  • Hyper-V 2012 R2 does not disable the protocols on the physical network adapter

    Hello, 
    I have a problem with the creation of an external network in Hyper-V (2012 r2), when I create the external network does not want to share with the host, therefore I take the check to share it. Hyper-V on the network adapter "real" does not disable
    all protocols, but active all inclusive TCP4 and 6. 
    How so? 
    I have 2 other servers with the same configuration and run regularly.
    Thanks in advance

    Hi Fabio,
    "when I create the external network does not want to share with the host, therefore I take the check to share it. "
    Based on my understanding ,after creating a external Vswitch  the physical NIC will only have protocol  "hyper-v external virtual switch " whatever we check "allow management operation...." or not .
    Do you mean after you create the external Vswitch , the physical adapter still have another protocol ?
    If yes , my suggestion is to remove the physical NIC from "device manager " , then restart server and reload the driver  then create the external Vswitch again .

  • Hibernation Mode - Network Adapter is Disabled (svchost.exe)

    Everytime my my x60 goes into hibernation mode, the network adapter is disabled and my internet access obviously interrupted.  Sometimes I can just disable/enable the adapter to get going, but many times I have to restart the computer - very annoying, especially when you're working online on something...
    Anybody else got an issue with this?

  • Enable and Disabling the Network Adapter with domain user (Standard User)

    Hi Guys. 
    We setup a active directory in our organization. Added client systems(Windows 7 and Windows 8) to the Domain. Domain users are accessing the system with standard users permission. I don't want to give Administrator permissions. But user should able
    to Disable and Enable network Adapter without giving the administrator permissions. Please suggest . 
    Thanks in advance for the help :)

    Hi,
    According to your description, my understanding is that you want the standard user has the permission to disable/enable network adapter.
    I recommend you to implement this function by group policy:
    User configuration - Administrative Templates – Network - Network connections
    Enable this policy:

  • Update to iTunes 10.6.3.25 disables network adapter

    I am having a very difficult time trying to update to iTunes version 10.6.3.25 on 32-bit Vista Home Premium.  The installer completes successfully, but about 2/3 of the way into the install (I am assuming when the Apple network adpaters are installed), I lose my internet connection.  It doesn't matter if I am WiFi or if I am plugged into ethernet.  Not a problem, except that I can't re-establish it after the install is complete. 
    My initial update attempt was done using the Apple software updater.  However, that install crashed.  I removed iTunes completely and now have been using the installer program from the iTunes website.  I have downloaded the installer multiple times, each time with the same result.
    The real PITA is that a simple uninstall won't restore the network adapter performance.  I have to use a restore point to get back to where I can connect to the internet.
    Any suggestions about how to fix this problem?
    - Pete

    I'd try the install again, and then apply TG10987's instructions from the following post:

  • Broadcom 802.11n Network Adapter not working on Windows 7 64bit

    As the title suggests, my laptop (Alienware m17x) is installed with the Broadcom 802.11n Network Adapter and Windows 7 64bit Home Premium.  I have had several other driver incompatibility issues with Windows 7, but those I have slowly been able to resolve.  This however just cropped up after two months of successful use.  Yesterday it started failing to connect to the internet, telling me that no wireless connections are available.  I live in a dorm, and everyone else on my floor has successful wireless, including my Ipod Touch, PS3 and XBox 360.  I called Alienware/Dell Support and we spent hours trying to fix the problem and all look well until I rebooted my laptop this morning and the same issue reappeared.  When I reboot my laptop, all I get is a notification that no networks appear in range.  If I uninstall the broadcom chip and let windows install it after a boot up it works until the machine is rebooted a second time.  I have tried over a dozen windows 7 drivers for the chip, and about half a dozen vista drivers and they all have the same results, works on the first boot, fails every time after that 

    Just registered to say, on an Alienware M17x system as well running Windows 7 Ultimate, here is a link to a solution that worked exactly for me:
    http://forum.notebookreview.com/alienware/436486-guide-properly-solve-wireless-connection-problems-m17x.html
    All I did was section I.a. If the link is down, I copied the only section that I needed to follow out of this guide, in order to get my wireless to work repeatedly without having to uninstall the wireless driver every single reboot. Now it works perfectly,
    already connected to a wireless network on startup.
    I.a. Disable Device sleep on disconnect
    Some newer Nvidia Ethernet drivers have a feature called Device sleep on disconnect. This is the culprit. Normally, it should only put the Ethernet adapter to sleep when the cable is disconnected, but it's buggy and thus kills the wireless connection as
    well.
    Follow these steps to disable this feature on your Nvidia Ethernet Adapter:
    1. Open the Windows Device Manager by hitting Win+Pause, then click on Device Manager on the left side.
    2. Double-click on Network adapters.
    3. Double-click on NVIDIA nForce Networking Controller (yes, that's the wired Ethernet adapter indeed).
    4. Click on the Advanced tab.
    5. Select Device sleep on disconnect.
    6. Set the Value to Disabled. 
    7. Click OK and wireless should work again (might require a reboot afterwards, but probably not).

  • Windows 8.1 Enterprise Evaluation- Strange behaviour of network adapter

    Hello there are discussions and questions around this community about network adapter dropping connection while system is running. But I have found unique problem with my network adapter driver.
    I have tried to state my problem as clearly as possible. Please ask if any detail is required.
    My network status shows no access on following occasions:
    1. On alternate system wakeups.
        eg:  
    a. System boots up 
    Internet accessible
    no problem
    b. I put system to sleep(first time) and wake it up
    No access to internet !!!
    When I check in network and sharing center not even adapter shows in disabled status.(See video from the link given below).
    c. Without restarting system or without installing network adapter again,  I put system to sleep again and wake it up (2nd time).
    Internet accessible
    d. I put system to sleep for (3rd time) and wakes it up.
    No access to internet!!
    If I put system to sleep again and wake it up definitly I get network access.
    2. If I switch off the modem before windows shutdown completely or in the process of shutdown, next time when I boot system, even though the modem is switched on before booting the system, No internet access tooltip will be shown on network
    sysbol.
    Another strange behaviour is on no internet access status, I start installing adapter, and it loads required files and prompt me to click "next" and "click" install.
    But the thing is before I go to "next" button, I will get network access as shown in this link
    http://youtu.be/sPlXVEiYBeo. Ignore virtualbox adapter. Same behaviour was there when there is no vbox adapter. Same was happening in Windows 8 Pro, but not in windows 7, so that there is no H/W problem I think. 
    Any idea on how to fix this or any alternate solution ? 

    Hi,
    Firstly, access your network adapter official website to get the proper driver applied to your system.
    Then going to Control Panel > Device Manager, right click your adapter > Properties. Under the Power Management tab, make sure "Allow the computer to turn off this device to save power" checkbox unchecked.
    If it still persists, try to disable "fast startup" as below steps:
    1.In Control Panel, open the Power Options item.
    2.Click the Choose what the power buttons do link.
    3.Clear the Turn on fast startup (recommended) check box.
    4.Click Save Settings.

  • Windows 7 x64 Network Adapter Stops working on high load

    My Network has been failing and it has been happening for about a month or so on Windows 7 x64.  I dont think that the system configuration is the problem as it is happening on 2 seperate machines.  One being a relatively beefed up "white" box, 4 gig OCZ ram, EVGA nForce 790I SLI Mobo, Q9600 Quad core processor, dual raid 1 - 150 Gig Raptors, 2 8800GTX SLI cards, Pure Power 800W PS.  The second machine is an IBM Netbook S10.  I use the Netbook as a media center connected to a Pioneer Elite 1050HD.  One thing is I have a PS3 and have several 1TB Esata drives connected to an IOGear 3132 Esata 3.0Gb pciX card to my desktop.
    My typical usages:
    1. FTP from a private server
    2. Streaming music via Winamp
    3. Streaming video 720, 1080 from pc to PS3 via the PS3 Media Server
    4. DLing demos or movies on the PS3
    5. Network streaming a movie from the Esata drives to the bedroom or kids rooms
    6. Streaming video from abc.com or southparkstudios.com from the Cox cable modem
    7. RDC over VPN to work machines
    Now I have noticed that when I am streaming HEAVILY, from any 2 of the above mentioned, my network connections will simply stop working with a yellow exclamation mark on the task bar network icon after a few moments, nothing in the event logs, no logs or ANYTHING at all.  It will simply stop working no notifications or anything poof, gone.  I have EVERY single patch, driver anything I can think of installed.  Nothing works, the timing is completely random.  FYI I have a NETGEAR ProSafe VPN Firewall FVX538 with a cable modem connection on WAN 1 and a cellular connection on WAN2, these have no impact I feel on the connections because the PC may go down or the Netbook will go down depending on which one has the most load.  So this simply tells me that it it not a firewall router problem as I have tried using a cisco unmanaged 24 port 1GB switch and I get the same problems.  From analyzing the systems and layout I am led to believe that it is either a network adapter driver OR a Windows 7 problem (collisions, unhandled exception?), this NEVER happened with XP or Vista.  I have tried everything but a new network adapter, I have tried the secondary adapter card on the mobo, I have tried bridging the two, I have tried daisy chaining the switch and putting each machine on its own dedicated switch linked to each other with no change.  When the network goes down it is only that box effected, all other machines still connect to each other fine, only the one with load shuts down and the only ones that shut down are Windows 7.  These machines are all wired with commercial cat5e patch cables, they have all been swapped for new ones lately.  All networking and PC equipment are on UPS so I doubt voltage variations.  Windows Firewall is disabled I only use the hardware firewall, I do not use any antivirus.
    I am completely out of options, can anyone recommend a new route?
    In addition when I go to the command prompt and attempt to do an ipconfig /release.  I get an error saying that the adapter is not in a usable state.  Very irritating, this forces me to reboot, or right click disable/enable on the network adapter.  The right click route takes almost a minute to complete.
    Tried update driver in nvidia control panel, no luck.  I have also turned off the networking power saver option in the adapter settings.

    Hi,
    Considering this issue occurs on 2 different machines, I also think this issue may be more hardware related. You may also try the following:
    1.    If the computers are connecting to a router, please ensure the router’s firmware is up-to-date.
    2.    Please run the following command in an elevated command prompt in Windows 7:
    netsh interface tcp set global rss=disabled
    netsh interface tcp set global autotuninglevel=disabled
    netsh int ip set global taskoffload=disabled
    3.    Disable SNP in Windows 7 by setting Registry as following:
    Note: Please perform a full-system backup first.
    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
    EnableTCPChimney=dword:00000000
    EnableTCPA=dword:00000000
    EnableRSS=dword:00000000
    If the keys do not exist, please create them and assign the value.
    An update to turn off default SNP features is available for Windows Server 2003-based and Small Business Server 2003-based computers
    4.    If the issue persists, please add another network adapter to this computer and see how it works.
    Hope this helps. Thanks.

    Hi, I'm experiencing a simular problem here.
    My PC was using Asus P5Q-E motherboard but exchanged it for Asus P5Q TURBO Pro because it loses 'connectivity ' after an interval between a few hrs to 26hrs. During this state, I can't browse or my Outlook to check emails. The only thing that can send/receive data is Vuze. Plus, the strange thing is that the network icon says there's nothing wrong at all (when it obviously there is). Even the currency desktop gadgets says the time elapsed since it 'lost connectivity '.
    I initially thought P5Q-E was faulty so now I'm using the TURBO Pro. However, the problem still persisted.
    I am using Win 7 Ultimate x64 with all the updates and drivers. Connected via LAN cable to the router and the firmware is the latest. My ISP sent me a replacement router to confirm that their equipment is not faulty, which is true.
    I have tried the above methods 1-3.
    Although I'm not sure if I implemented Method 3 correctly since I don't usually go to the registry but here's what it looks like after creating it:
    EnableRSS   REG_DWORD   0x00000001 (1)
    EnableTCPA   REG_DWORD   0x00000001 (1)
    EnableTCPChimey   REG_DWORD   0x00000001 (1)
    There are 3 more PC's and 1 laptop in the house. 2 PCs use Win XP, 1 uses Win 7 Ultimate x64 and laptop uses Linux Ubuntu.
    My PC has a second OS, Linux Ubuntu, I used it to time trial both motherboards (before and after switching) and found no problems at all even after 48hrs, so it confirms it's not a hardware issue.
    The other PC's apart from mine are connected wirelessly. As far as I've been told, they don't experience the same issue I have.
    I've been trying to tackle this problem for months now and I'm frustrated to reboot my PC every time it 'loses connection '.
    I chatted with Asus about the issue when I still had the P5Q-E mobo, they said that they built a simular system to mine with the same mobo and said they couldn't reproduce the problem I'm having. THey even tested on other mobos with the same LAN chip and found nothing wrong. That's why I got the TURBO Pro that has a different LAN chip.
    Anyone got anymore suggestions???
    Thanks in advance.

    8.- repeat steps 6 and 7 until you have uninstall all network adapters.
    9.- in the menu bar on top click on "search for hardware changes".
    10.- its done, the pc will look for the drives by it self, and if it dosen´t, just put in the dvd and ask it to browse your dvd for the drivers.
    hope it works on you guys.
    best regards

    Hi peye,
    I don't believe the problem is necessary the platform service, but a combination of your Anti-Virus and the Platform Service.
    Try this:
    Change Platform to Automatic again. Disable or temporary uninstall your Anti-Virus and see what happens.
    Report back.

  • Cannot create new virtual network adapter on logical switch team

    I am currently moving from Hyper-V 2012 to Hyper-V 2012 R2 and in turn I have just installed SCVMM 2012 R2. I am using SCVMM 2012 R2 to create some NIC teams which I have done no problem in the past with SCVMM 2012 SP1. Now we have everything set up just
    like we did in the past and it seems to create the NIC team just fine. The problem is when I try to create a New Virtual Network Adapter, when I click the button, it immediately says:
    VMM cannot create the virtual network adapter. Either there are no VM networks associated with the network sites that the uplink port profile "Logical Network Name" Connects to, or the VM networks associated with those network sites all use Hyper-V
    network virtualization.
    Now I've checked and the VM Network is assigned to the logical network that is associated with the Network Site that contains the host I'm working with. I've also tried disabling Hyper-V network virtualization but that didn't change anything and I thought
    that it's always enabled on 2012 R2 anyway.
    I would like to gain network connectivity to this team at least for testing purposes and we also are planning on building a Hyper-V cluster. Were some new restrictions added in 2012 R2 to prevent creating virtual network adapters in this scenario or am I
    doing something wrong?
    Any information would be helpful. Thank you in advance for your time!
