Intel 4965 AGN + Windows 8 RTM 64-bit = Random BSOD (netwlv64)

Fjtorsol Community Member

No matter if using the drivers included with Windows 8 or the latest available from Intel downloads page (13.4.0.139) it causes random BSOD's. I have two crash memory dumps to prove it. In addition (if it wasn't enough) the DPC latencies issues that used to take place with Windows 7 64-bit (RTM-SP1) have turned from 1000 micro-seconds spikes every 10 seconds to constant >1000 micro-seconds latencies with >16000 micro-seconds spikes that cause 5-10 seconds audio drop-outs. Of course disabling the wireless adapter solves all the problems but considering a laptop is meant to be wireless this makes no sense. Also the Windows event viewer shows unidentified events with ID: 5010 for "netwlv64" in groups of 10+ with few hours of intervals between them.

    Thanks for the answer anyway as it is kind of difficult to dictate a memory dump via phone I would like to do this through e-mail. Which options do I have?

    I have similar issues. Randomly my Thinkpad X300 with Intel 4965AGN is going into a BSOD. I'va analyzed the memory dump files and it is also related to the NETWLV64.SYS driver. I'm running the same version of the driver (13.4.0.139). In my case it's always BAD_POOL_HEADER (19).

    Same Problem here on Asus V1SN using the same wireless adapter.

    Crashdump also points to netwlv64.

     

    BAD_POOL_HEADER (19)

    The pool is already corrupt at the time of the current request.

    This may or may not be due to the caller.

    The internal pool links must be walked to figure out a possible cause of

    the problem, and then special pool applied to the suspect tags or the driver

    verifier to a suspect driver.

    Arguments:

    Arg1: 0000000000000021, the data following the pool block being freed is corrupt.  Typically this means the consumer (call stack ) has overrun the block.

    Arg2: fffffa80081dc000, The pool pointer being freed.

    Arg3: 0000000000001010, The number of bytes allocated for the pool block.

    Arg4: ce0dca6d6158e85c, The corrupted value found following the pool block.

    I'm also experiencing this issue on a Dell XPS M1330 laptop.

    Wireless card is the Intel 4965AGN, and offender is netwlv64.sys

    I'm also having issues.  I have a Dell XPS M1530 which I've upgraded to Windows 8 x64.

     

    With the driver it automatically picked up during the install (13.4.0.139) it dropped the WiFi connection within minutes of connecting.

     

    I then tried installing the PROSet driver package from the Dell Driver Download site.  The driver is dated 08/08/2007 and is version 11.1.1.22.

     

    It seems to have improved things a little but it's still really slow and dropping out.

     

    I downloaded the latest version 15.2.0 direct from Intel site and that won't even install...it says it can't upgrade the existing version, even after I manually uninstalled the existing version and the uninstalled the driver from the card.

     

    I don't know if it's netwlv64.sys as reported here, I'm not very technical.   I don't actually know what a BSOD is!

     

    Please help, any ideas?

     

    Think it will ever be supported or do I need to go back to Windows 7? :-(

    Ouch, just stumbled across this:

     

    http://www.intel.com/support/wireless/wlan/sb/CS-033840.htm

     

    Here's the snippet below, says 4965AGN is not supported in Windows 8. 

     

    But the note says something about an inbox driver that works with Windows 8.  What is an inbox driver????

     

     

    Which Intel® wireless adapters are not supported in Windows 8?
    Intel® WiFi/WiMAX Link 5150
    Intel® WiFi/WiMAX Link 5350
    Intel® PRO/Wireless 2200BG Network Connection
    Intel® PRO/Wireless 2915ABG Network Connection
    Intel® PRO/Wireless 3945ABG Network Connection
    Intel® Wireless WiFi Link 4965AGN

    Note:The Intel® PRO/Wireless 3945ABG Network Connection and the Intel® Wireless WiFi Link 4965AGN adapters have an inbox driver that works with Windows 8. However Intel Customer Support does not support the use of Windows 8 with any of the above adapters.

    "have an inbox driver that works with Windows 8" -> So should we consider random BSOD's a new standard of "working drivers". After being many years having to cope with this mediocre support then they decide to stop supporting it before fixing any bug during the whole lifecycle of this product. I'll take it mind for my next purchases and recommendations. I thought it was impossible to pass AMD in poor support but definitely Intel has reached a new milestone.

    I have had exactly the same issue on an HP latop that has the intel 4965AGN. I've tried quite a few things like trying to use the windows 7 x64 driver for this card. They didn't seem to go on properly. I then read some stuff in the following post "Intel 4965AGN - Wireless drops out with Windows 7 until restart", which lead me try try disabling 802.11n, and simpy using 802.11g. In device manager, for this adapater, under the advanced tab, their is an item called "802.11n mode". I changed it from enabled to disabled. I am using the intel driver that i think came with windows 8, being 13.4.0.139. There is also a microsoft driver on the system which is 13.3.0.137 but i'm not using that. Anyway after disabling 802.11n things seem good. I've manged to download a 3.5Gb iso coming in at about 12 to 13 Mb/s and another of about 1.5GB. No drop out so far, whereas prior to this is was very frequently dropping and i could only get through 40 of 50 Mb of download before it died.  I have also tried re-enabling 802.11n and the problem comes back again. Its turned off again now and seem stable so far. I hope this helps out.
