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?

    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.

    I got it fixed for my Dell M1330 by using an old Vista Driver:

    No more BSOD since 4 weeks (since Dec 4th).

    Ditto.  Hopeless BSOD nightmare since upgrading to W8.1.  Always thought the BSOD thing was overplayed in my 25 years of Windows loyalty.  This is getting terminal.

    I had the same issue on my old Laptop HP 9xxxx.

    Strange enaugh, the problem appeared only after one month I installed Windows 8.1 from scratch.

    I noticed the issue disappearing when not using the wireless, although the driver was still loaded.

    I tried to install the latest Windows 8.1 driver from here: http://www.intel.com/support/wireless/wtech/proset-ws/sb/CS-034038.htm but the device manager keep showing the "old" Microsoft one.

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

    Now device manager shows the new version. So far so good, the problem seems gone.

    I hope this helps.

    How did the Atheros card work out; if you continued to use the T61?  Did you just use the driver that Windows supplied or did you use Lenovos of Atheros?  I have an R61 with the same 4965AGN card.
