NETw5s64.sys keeps on giving me bluescreens

[idata]

My new Clevo M570TU Montevina laptop has a Intel WiFi Link 5300 AGN with the latest driver running on Windows 7 x64 (13.0.0.107). I get bluescreens several times a day. If I leave the laptop on when I go to sleep, I often will find that it has automatically restarted because of a BSoD sometime during the night. The stop error is 0x000000d1 and I believe the BSoD says DRIVER_IRQL_NOT_LESS_OR_EQUAL refering to NETw5s64.sys.

It seems the BSoD occurs a lot when utilizing the my WLAN connection a bit more than just surfing. That is running 3-4 torrents, streaming Internet radio and surfing at the same time. I use the newest uTorrent client which again uses the latest Java RE (1.8.5 and 6u17). I am at the moment not using any anti virus software.

In addition to the bluescreens, I often lose my WLAN connection. WLAN is however fine on my other laptops. In these cases I get the event ID 5010 referring to NETw5s64 in my in my Event Log. I resolve this issue by disabling and reenabling the WLAN card, but this is very annoying.

I'm starting to think that the driver is faulty, WLAN on Windows 7 x64 is unstable at the moment, or that maybe my WLAN adapter is faulty.

I ran MemTest on my laptop the whole last night without any errors. I am considering trying another torrent client.

Anybody else having these problems? Any tips is highly appreciated as I'm getting fed up.

Update: I've disabled 11n and power saving on the adapter, but it keeps on giving me bluescreens. A Google search shows that this is a common problem with these Intel adapters. It would really be nice if Intel would acknowledge and address these issues.

Same problem with a Dell Studio 1557 wifi 5300 agn. Blue Screen (BSOD) during copying files to NAS. Driver 13.0.0.107, Windows 7 64 bit.

Hi there,

I just wanted to confirm that I got the same BSOD on a fresh install of Windows 7 64 Bits.

Driver: 13.0.0.107

BSOD error: DRIVER_IRQL_NOT_LESS_OR_EQUAL refering to NETw5s64.sys

Message for Intel: please update your driver or request us more information. I have the dump file and if I can send it to you if you want.

please let us know

Regards,

Didier

I've been getting the same BSODs and random network drops for months now with the 13.0.0.107 drivers and Windows 7 x64, running 5300 adapters in HP 8530w notebooks. For me it's pretty easily reproducible by transmitting >30-40mbps on a LAN and surfing the web at the same time. It's been happening ever since the first Win7 RC dropped, so it's not as if it's exactly a new problem either.

I had hoped to see better drivers (or other fix) once Windows 7 was released to retail, but it's been about 5 months now since Intel's last driver update and I've just about given up. If this doesn't get fixed soon, I'll definitely be looking for Broadcom wireless adapters from now on (I actually would have already ripped out these POS Intel adapters, but they're whitelisted in the 8530w BIOS.)

[idata]

I have been in contact with Intel Customer Support, and they refuse to give me support since my card is an OEM product. They told me to contact my reseller which I then did, but my reseller told me they don't have a support deal with Intel. I have since tried another wireless router (3COM vs. D-Link), but the bluescreens still came. My reseller is now offering me a replacement 5300 card, which I don't believe in, but maybe it's worth a try...

I just wish Intel could release a new driver since all the bluescreens people are having are pointing to the driver itself (NETw5s64.sys).

[idata]

My Dell Studio 1557 with wifi 5300 agn is only crashing when the files are going from the Laptop to the network (NAS or PC). I can download files with newsleecher without any problems. Copying to the NAS will give blue Screen. So replacing with another 5300 has no effect.

[idata]

Yes, I realize that, but that's what my reseller want to try in lack of better ideas at the moment...

[idata]

my x200 recently purchased had the same problem. I tried vista drivers etc. Same issue when downloading massive files BSOD - Bad Pool Caller. I reimaged a few times. I recently restored my image and haven't had a problem with the latest Lenovo/Drivers. I tried these a few times before also with BSODs happening. 13.0.0.107 9/15/2009. Vista drivers gave half the throughput but were stable.

[idata]

A quick update for everyone having this problem:

Microsoft has released a hotfix for BSODs very similar to these, caused be defective power management code. You can read more over at Ars Technica using the following link: http://arstechnica.com/microsoft/news/2010/02/microsoft-details-windows-7-memory-leaks-hangs-freezes.ars http://arstechnica.com/microsoft/news/2010/02/microsoft-details-windows-7-memory-leaks-hangs-freezes.ars

I won't be able to test this until next week, and you should use caution in applying this update as it hasn't been fully tested and might break more things than it fixes, but at least there might be a solution forthcoming (and I might owe one big apology to Intel's driver team.)

[idata]

Thanks a lot for that one, but unfortunately I have the same problems after the hotfix. :\

[idata]

I knew I was forgetting something - updating this thread. After some testing, the hotfix doesn't work for me either.

I did notice a new behavior while testing, though - it seems that the BSODs are much more likely immediately after a "recovery" reboot (regardless of hotfix/no hotfix.) I managed to get four of them in quick succession by starting some heavy network traffic immediately after rebooting, but things stay stable for much longer if I do a full shutdown/boot cycle after a BSOD reboot.

I don't know if that has any relevance to anything, but thought I'd mention it.

[Ilene_K_Intel]

Intel is aware of this problem and is actively working to resolve the issue. We will update this thread as new information is available.

Thank you,

IleneK

[idata]

I just wanted you to know that I just replaced my 5300 AGN with another unit from my reseller, but as I tought, it didn't help.

Anyways, thanks for the update IleneK. Makes things a lot easier when you acknowledge the problem. If there's anything I can do to help just let me know.

[idata]

I thought I'd post this here since it's a top result on google.

I've had Dell send me two new 5300s and a technician to replace my motherboard, but this exact problem continued. I asked them to send me a Broadcom NIC also known as "Dell WLAN 1510" and the problems stopped. The card will do as a replacement until Intel fix their drivers. So people who want to use N should demand their OEM to send them another 802.11n-capable non-Intel card with comparable specification. Dell customers should preferably ask for a card named 1520 since it's closer to Intel's 5300 in terms of performance.

[idata]

Update to the latest 13.1.x.x driver. It has a fix for all of these issues.

[idata]

Nice! I've just updated, and I'm crossing my fingers. Release notes doesn't say anything though.

[idata]

The new drive don't worked for me --> I've got:

Intel(R) WiFi Link 5100 AGN

Driver --> 13.1.1.1 (Date 13.01.2010)

on Windows 7 64bit Home Premium

Can you tell me the exact scenrario that led to this BlueScreen? What did you do exactly (step-by-step) that led to this?

[idata]

Like other User report, i've downloaded files with 600kB/s (my full range). The BSOD happens randomly...but i think it happens, when i use full speed. If you want some Minidump files or the bugreports of win7 .. just tell it..

i've got no BSOD, since the last one (which i posted).

[idata]

I have nearly the same problem on a brand new lenovo R400 with Intel 5100 AGN and win7 pro 64bit. I think its only happen in high load situations (downloading with almost 2mbyte/second) and additionally high cpu-load over night. The laptop crashed after 8 hour's, so the driver shows this symptoms only after a couple of hours i think´, but i will watch it the next days. Driver version is 13.1.1.1 (13.01.2010).

Thank you for any help or an updated driver

Thanks for the info. In order to help fixing this issue i need some more details:

1) What is the model of your AP? what is the AP configuration?

2) What kind of traffic are you passing (file transfer, video, etc)?

3) Is there any way i can get a kerner dump from you?
