Bug report: netwsw00.sys (6230, v15.3.x) BSOD on Windows 8 x64

[idata]

I have a laptop with Windows 8 x64 (with all the latest Windows Updates installed) with a 6230 card, running the latest 15.3.50 drivers found on Intel's website. When I connect my laptop to my Nexus 4 Android phone (using the WiFi hotspot tethering feature of the phone), I get a BSOD.

* I do NOT get a BSOD when I used my previous Android phone (LG P509, not sure what the WiFi chipset is) as a WiFi hotspot (yes, using the same computer, card, OS, drivers, etc.).

* I do NOT get a BSOD when I connect to my router's WiFi hotspot (Atheros AR9220/9223 chipset).

* I have NOT experienced a BSOD with any other hotspot that I've connected to.

* Reverting to the default driver that shipped with Windows 8 (14.2.1.3), FIXES the problem.

* I have another laptop, also running Windows 8 x64, but with a 6250 card running the latest 15.5.6 drivers, and there are no problems there, either.

* The latest Windows 7 drivers (15.3.1) exhibits the same problem.

* Sometimes it BSODs as it is establishing the connecting, and sometimes it BSODs after a minute or two of light usage after connecting. If it survives long enough to see some usage, the speeds are extremely slow.

* The BSODs always fault in netwsw00.sys, though the faulting code is often different. Sometimes it's an unhandled exception, sometimes it's IRQL_NOT_LESS_OR_EQUAL, etc.

* Sorry, I have not been able to test this with Windows 7, so I am not sure whether this is a problem that is specific to Windows 8.

So to summarize:

* 15.3.50 and 15.3.1 are both broken

* 14.2.1.3 (older driver) works

* 15.5.6 (newer driver, not available for the 6230) seems to work (or I guess it could be because of the different card/computer)

* I see this BSOD only when connecting to some hotspots (in my case, the Nexus 4's hotspot) while most other hotspots seem to be fine.

Also, why did the 6250 get the latest 15.5 update while the 6230 was relegated to 15.3? The 6250 was released in 2010, while the 6230 was released in 2011, so why is the 6230 seemingly relegated to a deprecated status, not getting a "real" Windows 8 driver (I inspected the driver's INF), while the *older* 6250 was one of the cards to get a "real" Windows 8 driver in the form of 15.5?

Rolling back doesn't sound too bad. Unfortunately, from what I can tell, Microsoft doesn't provide a default Intel 6235 driver for Win7. For Win7, Microsoft's Compatibility Center redirects straight to Intel...and that isn't helping.

This is a rare case where Win8 actually might have an advantage.

This is exactly what I did, and now BSOD is gone.

hope the old driver doesn't bring about other bugs.

Same problem with Nexus 4 in 4.2.2 + Centrino® Advanced-N 6235 (2230) with the latest driver 15.8.0 with Win 7 64 bit.

I don't know how to go to 14.2.0, if I unstall, at the restart it is reinstalled automatically.

And If I try to install the 14.2.0 it says it is already up to date :/

Hello,

I have the same issue with several Lenovo Laptops or Tablets (Win7 installed) and a Samsung Slate7 (Win8 installed).

The BSOD always occures after connecting to either one of these devices: Samsung Ativ S, HTC 8x/s Nokia Phones...But also several Android devices.

Really annoying that one driver can cause so much problems...

Hoping for a solution from you guys!!!

Same here, my notebook got reboot after connected to WiFi hotspot

Phone:Pantech A850L @ 4.1.2 (APQ8064)

Notebook:Lenovo E320 (Intel Wireless-N 1000 with driver ver. 15.4.1.1)

Enabling FIPS encryption solved this bug

It looks like Intel may have finally fixed this bug in the latest PROset/Wireless package, version 16.1.1, which was just released a few days ago, on August 7. I haven't tried it on Windows 8 yet, but I installed this package on my laptop with an internal Centrino Advanced-N 6230 adapter, running Windows 7 64-bit, and it brought the driver to version 15.9.05, dated 6/16/2013. I am apparently now able to successfully connect to the wireless hotspot on my Verizon Incredible 4G LTE (aka HTC Fireball model ADR6410LVW) running Android 4.0.4 without bluescreening. Prior to installing this latest driver, the laptop would consistently BSOD in under minute after connecting to the hotspot.

Can Confirm the newest drivers work in Win 7 x64. No more BSOD on my Laptop with Intel® Centrino® Advanced-N 6235 using my Droid Razr M Android version 4.1.2. Never went back to any drivers prior to 15.3, but any after would BSOD until I tried the newest in the 16.1.1 package, Driver Version 15.9.0.5. Hurray for WiFi :-)

I have a Lenovo Thinkpad X300, Win7 Professional (32 bit), Intel(R) Wireless WiFi Link 4965AGN, T-Mobile Hotspot on a Samsung Galaxy 4S Relay 4G, and have been getting the BSOD for months when I try to connnect. T-Mobile had a fix, then it didn't work when I reset the phone, and t-Mobile finally told me it was a BIOS problem.

Rather than believing them about the BIOS problem, I followed the advice here and on a related thread, /message/193197 https://communities.intel.com/message/193197:

• rolled back to earlier driver, 12.4.1.4 (dated 03/26/09), but still got BSOD.
• In - "Enable Federal Information Processing Standards (FIPS) compliance for this network." is unchecked.
• In - - -, disabled 802.11n Mode.

That seems to have solved the problem: no BSOD after an hour of using the Hotspot, speed roughly comparable to what I get on my Netgear router.

Not sure if a solution was found yet, but it seems kind of long for there not to have been. If you are still experiencing the issue, try updating the Intel drivers for the card in your Dell. The Dell drivers do not help.

I tested on other Dell Latitude E6430s and got the same bluescreen error. Reinstalling the drivers from Dell, installing optional components, adjusting the security to enable FIPS, and other items did not resolve the issue.

The fix is to download newer drivers from Intel's website. The ones on Dell's site are multiple versions behind.

I have a HP dv6 6023tx i5 notebook computer running Windows 8.1 Pro with a "Intel Centrino Wireless-N 1000" card. BSD occurred when trying to connect to a Lumia 820 WP8 phone (tethering wirelessly). Computer then reboots and after less than 3 mins reboots again - this happens continually until I turn off WiFi and tethering on phone. Computer then reboots normally. I can then turn wireless on again and provided I don't connect wirelessly with the Nokia Lumia 820 WP8 phone, my computer runs OK.

[Jose_H_Intel1]

Sharpis, you may want to contact Microsoft* for this issue since we currently do not have a driver for your wireless adapter in Windows* 8.1. The driver version 16.1.1 posted above by SundeyPSU fixes the issue in Windows* 7.

Ok, so when can we hope to recieve the same fixed issue update for 6250 on win7 x64?

Hello,

Here are some actions that may help prevent this situation.

- Download the most recent wireless driver version available from your http://Computer Manufacturer Support Web Sites/ Computer Manufacturer Support Web Site.

- Then go to Device Manager and uninstall the driver currently installed (make sure to check the option to Delete the driver software for this device).

- Proceed to install the driver you downloaded before.

* If the issue persists, follow the same process to uninstall and delete the previous driver, but using the most recent version of the generic driver from https://downloadcenter.intel.com/default.aspx?lang=eng Intel® Download Center (use the version that includes PROSet/Wireless Software), select the most recent depending on your OS and adapter model.

Also, make sure you apply the settings from the following document:
