    Wireless network disconnection with NETwNs64 event log

    keitaroimai

      Operating System:    Microsoft Windows 7 Professional(6.1.7601 Build 7601)

      I'm using  Intel(R) Dual Band Wireless-N 7260  and the driver version is  18.33.12.2 which is the newest one I think.

      My wifi network is disconnected frequently with "NETwNs64" event log which ID is 5007 and 5032.

      But the NETwNs64 is missing in my computer. So I can not see the log detail.

      I can not fix this problem until OS reboot.

      How can I fix this permanently?

          Hello keitaroimai,

          Thanks for posting in our communities. We understand that you're experiencing wireless disconnections on your system.

          Do you remember if the system was working properly before? If so, have there been any recent changes on the system such as operating system updates or new software installed?

          For now, please test a clean driver installation using both the Intel latest generic driver and the OEM driver:

          1. Download and save your driver of choice. You can: 
            1. Get the latest system-specific driver from your computer manufacturer support.
            2. Download the Latest Driver for Your Intel® Wireless Adapter.
          2. Uninstall the Intel® PROSet/Wireless Software. 
            1. Open Programs and Features (Uninstall a program) from the Control Panel.
            2. Select Uninstall or Change and then Remove.
            3. When prompted, choose to discard settings.
          3. Uninstall your wireless driver. Windows* with an inbox driver may natively support some wireless adapters. You cannot uninstall an inbox driver. Proceed to the next step if you start seeing the same version of the driver installed automatically after it’s uninstalled. 
            1. Go to Device Manager.
            2. Expand the Network Adapters category.
            3. Right-click your Intel Wireless Adapter and choose to uninstall it.
            4. Make sure to select the option to Delete the driver software for this device.
          4. Clear out your temporary files. 
            1. Press the Windows* key and R key simultaneously to open the run box.
            2. Type in: cleanmgr.exe and press the Enter key or OK.
            3. Place a check mark next to Temporary Files. You can leave everything else checked or unchecked.
            4. Press OK and wait.
          5. Reboot your computer.
          6. Locate the driver you downloaded back in Step 1. Run as administrator and follow the wizard to completion.
          7. (Optional Step) Apply the Recommended Settings for Wireless Connectivity.

           

          Please let us know the results.

           

          Best regards,
          Eugenio F.

            Thanks for the response.

            I tried the procedure you provided.

            But the result was same.

            Can I have any other fix?

                Thanks for the reply.

                Here is the system information and logs.

                The event happens at 2018/06/06 08:15:19.

                Usually it happens once a day in the morning(not fixed time). But sometimes happens many times per day.

                 

                Thanks.

                  Hello keitaroimai,

                   

                  Thanks for providing the requested logs.

                   

                  We noticed there are two "Microsoft Virtual WiFi Miniport Adapter" under network adapters. Are you using hotspot, ad-hoc or other hosted network features on your systems? If not, we recommend disabling them. You can do that from an elevated CMD using the following commands:

                   

                  • netsh wlan stop hostednetwork
                  • netsh wlan set hostednetwork mode=disallow

                   

                  If the issue persists, please confirm the following:

                   

                  • Are you using any secure connection protocols or software? This is common on business private networks.
                  • Do you have the same results if the system is connected to other networks?
                  • When you tested the clean driver installation, did install the OEM (Lenovo*) drivers as well? You can download them here. You might want to update your BIOS as well from the same site.

                    Hi,

                     

                    I tried followings but the result was same.

                     

                    netsh wlan stop hostednetwork

                    netsh wlan set hostednetwork mode=disallow

                     

                    • Are you using any secure connection protocols or software? This is common on business private networks.

                     

                    I'm using just a home network.

                     

                    • Do you have the same results if the system is connected to other networks?

                     

                    yes.

                     

                     

                    I also tried but nothing changed.

                     

                    Thanks.
