As we understand, you system is having BSOD's when using IPsec, and it is reporting the Intel® Dual Band Wireless-AC 8260 driver as the culprit. Here are a few items for your consideration based on the our review:
- Please perform a clean install of the Intel® PROSet/Wireless Software and Drivers for Windows® 10 [19.30.0]. We know you tested this already, but this is the recommended driver version.
- Go the Device Manager, under network adapters, look for the Wireless Adapter and open the properties. Go to the "Power Management" tab and toggle Off the option "Allow the computer to turn off this device to save power".
- Go to the Power options of your laptop, in the Advanced Settings for your Power Plan, and make sure that the Wireless Adapter is set to work at "Maximum Performance" when plugged in and on battery.
We would like to mention that we have had similar reports of BSOD's in Windows® 10 pointing to the Intel® Wireless driver; in some cases this was due to 3rd party applications and malfunctioning filter drivers. In this scenario, the users solved this by uninstalling, or updating the 3rd party software.
Some of the common types of apps we have seen are: Network monitoring software, VPN software, Antivirus, Video/audio streaming apps.
I have uninstalled the driver (including removing existing settings), reinstalled and rebooted. Crash in netwtw04.sys occurs as before.
Power management settings for the Wireless-AC 8260 are not available as shown in the screenshot below.
The only Power Plan available on this machine is Balanced, and Advanced Settings does not support adjusting anything except lid/button actions, low-battery actions and screen saver timeouts. The OEM control software's ("Vaio Control") performance setting is already set to "Performance".
No third-party antivirus software, VPN software or similar is running. No streaming apps are in use, and the crash is easily reproduced with nothing besides a browser and Powershell running.
It seems that this PC has customization for wireless and power, since some common settings cannot be modified. We strongly advise you to engage the Computer Manufacturer Support about this as well.
In our best effort, you can try using the generic version of PROset, but with the "Driver Only",
1. Download Intel® PROSet/Wireless Software and Drivers for IT Admins, 19.30.0 for 64 bit. File: Wireless_19.30.0_Driver64_Win10.zip
2. Extract the contents of the zip file to a known location in the computer.
3. Go to Control Panel, Programs and Features and Uninstall "Intel® PROSet/Wireless Software". When prompted, choose the option to "Discard settings".
4. In Control Panel, Device Manager, Network Adapters, right click on the Intel® Dual Band Wireless-AC 8260 and Uninstall it. Make sure you mark the option to "Delete the driver software for this device".
5. Reboot the PC or scan for hardware changes, check device manager and if an older wireless driver is detected and installed, repeat the actions to uninstall and delete it as well. Repeat this process until the OS does not allow deleting the driver, or until the controller shows as Unknown Device.
6. Remove temporary files: Press the Windows Key + R to open the run box. Type Cleanmgr.exe. Press OK. Select the main drive, usually C:\. Check Temporary Files and uncheck everything else. Press OK.
7. Go to Device Manager and locate the 8260 (it may be an unknown device), select the option to install the driver and browse to the location where you extracted the driver files.
If the issue persists, we would advise to engage Vaio* Support, and install their software version. The driver or software for your Intel® component might have been changed or replaced by the computer manufacturer.
Feel free to contact us if you have any additional questions.
Thanks for the tip, looks like the vendor driver was using some trickery to stay installed. (It would be nice if the ProSet exe installer would give a warning if the driver is not the expected one at the end of setup.) I removed all prior versions from the driver store, uninstalled the driver (with delete driver enabled) from Device Manager, verified that the driver store was clean, installed the 10.30.0 bare driver, and now I'm seeing version 10.30.0.4 everywhere.
Unfortunately, this does not help, and the crash occurs as before.
Looks like the Power Management settings are disabled on Connected Standby devices for network adapters as described in this Microsoft support article (as apparently are the advanced power plan settings mentioned above): https://support.microsoft.com/en-us/help/2889143/power-management-tab-is-not-visible-for-some-wireless-network-adapters-with-always-on-always-connected-aoac-platforms-on-windows-8
Disabling Connected Standby (by setting CsEnabled to 0 in the registry) makes these settings available again. However, the crash in netwtw04.sys stil occurs even after power management was disabled as specified in your earlier reply. Dump info from the latest driver is attached.
We would like to review some details of the system, please provide the following:
- Download Intel® System Support Utility with the adapter working fine, run the tool and use it to create a report with all sections, on the next screen, Save the report to a file. Then use the Advanced editor options to add the resulting XML file to your post as an attachment.
- Reproduce the issue and collect system event logs:
1. Clear the system event log.
a. Launch Event Viewer by clicking Win+X and select “Event Viewer”
b. Select “Windows logs” and right click on “System”
c. Select “Clear log…” and “Clear”
2. Close or minimize Event Viewer”.
3. Reproduce the WiFi issue.
4. Open Event viewer and navigate to System.
5. Right click on “System” and select “Save All Events As…”
6. Zip and upload the system log file.
We will need some additional information about your system in order to issue an accurate analysis. Please check your Private messages for further details.

I can confirm that this crash is fixed with the 19.50.1 driver release. Thanks to Intel for resolving this.
Thanks for the update. We are glad to know that the new driver worked for you and that your system is working fine.
I'm still having this same problem with the newest driver release. Only way for me to keep from bsod is to disable the wifi driver. My pc is a alienware aurora r6 thats 3 weeks old and has done been sent back to them twice. To fix the issue.
BSOD's can be caused by many reasons. Please let us know you are using an IPsec transport mode policy in your environment as reported in the original post.
If the BSOD's are caused by a different reason than the one mentioned in this thread, please create a new question in the Wireless Networking Support Community.
