Windows 8.1 BSOD: netwlv64.sys

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?

    Eventually I installed the Windows 7 64 bit one (14.3.1): http://downloadcenter.intel.com/Detail\_Desc.aspx?agr=Y&DwnldID=21049

    Hi Alessandro,

    Just curious...what is your driver version now? I've been having the issues with 13.3.0.137. When I install the new driver (15.3.1 or 14.3.1 as you did), the version updates to 13.4.0.139 for the netwlv64.sys driver.

    Thanks,

    Chris

    Hi, confirmed.

    According to my Device Manager is 13.4.0.139 as well.

    I keep believing the last version proposed by Intel, including for W 8.1, is 32 bit only. I see no reason why they split between 32 and 64 until the last W7 version I've installed.

    So far, so good. Touching wood (in Italy we touch iron, though... :) )

    Problem solved...I hope...it should be...I hope. Replacing with supported Intel 6300 wifi card. Simple, easy, a cheap upgrade and most importantly, no more BSOD! I hope...I feel good about it...I think.

    So, is there an alternative card other than the 4965AGN  that can be used and is supported? Pretty ticked I have to revert to an inferior OS just so I don't lose any more vital work.

    Also, why would it work and then not and then work again? Either the damn thing works or it doesn't is how it should be.

    Check my post above. Did you try installing the Win 7 driver? I had to use the last driver labelled 64 bit. For some reason the other didn't upgrade the driver, I'm wondering if they're 32 bit only.
