Windows 8.1 BSOD: netwlv64.sys

Anonymous

My Windows 8.1 Pro running on HP 8510w mobile workstation keeps crashing with a Blue Screen of Death STOP error on random accasions.

Bugcheck code 0x000000d1, DRIVER_IRQL_NOT_LESS_OR_EQAL in netwlv64.sys

The driver is related to the built-in Intel WiFi Link 4965AGN WLAN module.

This is a fresh installation of Windows 8.1 Pro. Using default Microsoft driver for the wireless module:

Driver Provider: Microsoft

Driver Date: 15.08.2010

Driver Version: 13.3.0.137

There is no driver for Windows 8.1 provided by Intel for this module. The one from Microsoft obviously does not work properly and crashes Windows 8.1.

There is another issue with this driver not re-connecting after standby but this I was able to resolve by disabling 802.11n Mode in advanced device properties (device manager). But this is another topic.

There seems to be something seriously wrong with the driver Microsoft provides and Internet research provides many results about people having the same issue. Does anybody have an idea how to fix the issues?

    Still no crash here (5 days). Try a vista x64 driver (from your manufacturer...preferably...I guess).

    BSOD!!

    Well I have now been hit by this same problem also...

    I have been a VERY HAPPY windows 8.0 user without any issues.

    I have the Wifi Link 4965AGM wifi hardware in my Zepto 6625WD laptop and all worked super nice before windows 8.1

    Now I have see the BSOD screen twice with the exact same details as you all write!

    Why is this 8.1 update destroying our good windows 8.x experience??

    I _REALLY_ hope Microsoft is finding a solution for this issue???

    PLEASE....

    Provider: Intel Corp

    Version: 13.3.0.137

    Still stable since this morning with the vista driver (v12.4.3.9 - 2009).

    My pc only crashes once a day max. So we'll see in a week.

    Lucky you. Well, once a day... I am used to reboot my machine once every month when Windows updates are released.

    Well, going to install Linux now.

    I have done a bit of of research on the Intel web page and found that Intel seems to have dropped support for 4965AGN WiFi chipset somewhere between version 15.3.1 and 15.3.50 releases made on the same day. All following driver versions do not support this chipset.

    So I have installed version 15.3.1 now and my device manager now shows:

    Driver Provider: Intel

    Driver Date: 07.10.2010

    Driver Version: 13.4.0.139

    Interestingly the data matches the one from the "Microsoft" driver quite well. I guess the Microsoft driver is just based on Intel 13.3 edition drivers released a couple of months earlier.

    What I could test already is that also with the Intel 13.4.0.139 driver the card won't re-connect to wifi after standby resume. This time I just disabled MSI in the registry for this device rather than disabling 802.11n mode in device properties. It seems to fix the resume issue for me on the Intel 13.3.0.139 driver:

    Windows Registry Editor Version 5.00

    [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\PCI\VEN_8086&DEV_4229&SUBSYS_11018086&REV_61\4&34ad53c6&0&00E1\Device Parameters\Interrupt Management\MessageSignaledInterruptProperties]

    "MSISupported"=dword:00000000

    NOTE: You might have to adapt the device identifier (VEN_8086&DEV_4229&SUBSYS...) according to your hardware.

    Though I have little hope that the driver will run stable for hours as it seems to behave exactly like the Microsoft driver (which is likely just re-branded Intel driver too).

    I still wonder why the WiFi driver which was working fine with Windows Vista, 7 and even 8(.0) can crash the Windows 8.1 kernel so badly.

    Update: I still had to disable 802.11n mode as standby resume issue was not fixed by just disabling MSI. I suspect this time it just took longer for Windows to notice that connection is actually lost after wakeup. This time the driver behaves quite randomly. Even with 802.11n mode disabled it sometimes does not return from standby and is unable to connect to any network after resume. The only way to revive it is to reboot or disable/enable the device.
