    Intel My Wifi - Centrino 6200N - BSOD


      First let me say that I have updated all drivers to their latest versions (as far as I can tell), and have no other issues with my wireless connection.


      So here's the problem:


      Using Intel My Wifi, I attempt to connect my Motorola Droid phone to my computer with ICS enabled. My laptop is connected to a LAN via copper, and I am using My Wifi as a mobile hotspot. I am actually able to connect, get an IP, and transfer data on my phone via wireless. After maybe 10 seconds, I get a BSOD, showing DRIVER_IRQL_NOT_LESS_OR_EQUAL.


      EDIT: I should also mention this happens when I use the software Connectify as well (known to be buggy, so I initially thought it might be that).


      Here is the output of the crash dump file:

      So the obvious offender is NETwNs64.sys, which I'm almost certain is the wireless driver for my laptop (again, Centrino 6200N).


      Otherwise, I have no issues - if it helps, my laptop is a Thinkpad T410, but I have found nothing specific to this on the web. This happens 100% of the time. I'm running Windows 7 4bit SP1. Look forward to any ideas, help, or direction on this issue.

          wow - amazing that no one has had this issue?

          • 2. Re: Intel My Wifi - Centrino 6200N - BSOD

            I have a similar issue - but not the same.


            When I put the computer to sleep, RANDOMLY, it hangs then BSODs.

            The BSOD view points to NETwNs64.sys.


            The issue is related to a DRIVER_POWER_STATE_FAILURE - 9F error.


            HP8540W with 6300N adapter.

            I have the latest of drivers and updates.


            No Idea??????????????????/

              I've a similar problem... everytime I use skype, download a torrent or do any heavier use of bandwidth I get a BSOD. I have been updating my wifi driver for the last 6 months hopping this bug gets fixed...

              • 4. Re: Intel My Wifi - Centrino 6200N - BSOD

                Ive got Win 7 64bit Home SP1


                Using ICS without Intel My WiFi software.


                ICS is connecting my external USB Clear wireless to my "virtual" Intel Centrino 6250 AGN


                I have tried:

                Set all network adapters to not use power management.

                Turned off motherboard "realtek" ethernet.


                I connect to the hotspot hosted by virtual miniport adapter using my droid 2 and after a little http browsing I get the BSOD.



                • 5. Re: Intel My Wifi - Centrino 6200N - BSOD

                  Yep, that's exactly what's happening on mine.


                  It's amazing no one has commented other than "yeah, me too".


                  There is obviously an issue with the 64bit drivers, anyone in the know care to enlighten us?


                  "We're working on it" is an acceptable answer (for me, at least).

                  • 6. Re: Intel My Wifi - Centrino 6200N - BSOD

                    I have the exact same problem on my Thinkpad Win 7 ultimate 64-bit, though my drivers are even more recent version 14.0.. 04/01/2011, and I still have the problem. I hope that they are working on this.  I hope there are new drivers forthcoming, this problem is very bad.

                    • 7. Re: Intel My Wifi - Centrino 6200N - BSOD

                      I also have a brand new Dell L502X laptop with Centrino Advanced-N  6230 and have been having a lot of BSOD while connecting to Wi Fi.


                      The BSOD shows DRIVER_IRQL_NOT_LESS_OR_EQUAL and that  the bug is related to NETwNs64.sys. Has anyone had any luck solving this  issue?


                      Any ideas or suggestions will be really appreciated.

                        Let me also join this me-too group.  I have an HP Elitebook 8540p with Windows 7 Ultimate x64, and HP Softpad has been urging me to "upgrade" the 6200N driver and software to version 14.0.  But everytime I followed this advice, I got a BSOD before the log on screen was seen.  Fortunately, the computer allowed me to log on after a reboot, and eventually I "downgraded" the driver to version 13.4 and the computer was fine again.


                        The BSOD screen also indicated that there was some problem with NETwNs64.sys.

                          Suppose the more info the better, and it keeps this thread alive.


                          I have an Alienware M15X laptop with an Intel Wifi Link 5300.  I've been using it since April without the My WiFi software (although I knew the entire time it could perform the My WiFi functions, I hadn't found out how).


                          A few days ago, I found the software on Intel's website to activate the My WiFi and enable internet sharing.  Things were going alright for a few minutes with my HTC Evo 4G connected, but suddenly my laptop blue screened.  I restarted, got everything running again, and re-enabled internet connection sharing.  Sure enough, a few minutes later it crashed again.  Since then I've been running it without ICS enabled, and it's been completely stable.


                          Any fixes or driver updates would be awesome!

                                I went to...

                                Make a system restore point.


                                Uninstall the Intel(R) Centrino(R) Advanced-N 6200 AGN adapter fro the device manager.


                                Restart your computer.


                                I then double clicked on ICS_s64.exe, choose custon to make sure everything was going to be installed. I then installed and restarted one last time. I then connected and everything seems to be working fine

                                  Same exact problem here.

                                  Brand new Sony VAIO VPCS132GX.

                                  Internet connection is Wired, and I share the connection using Intel's My WiFi from Intel PROSet Wireless Software 13.5.0 (it seems 14.1.1 discontinued support for the 6200 hardware).

                                  Connecting my Droid phone works fine for a while, but immediately upon starting "Good for Enterprise" on the phone, the laptop BSODs in NETwNs64.sys.

                                  • 14. Re: Intel My Wifi - Centrino 6200N - BSOD

                                    I get the same BSOD as everyone else.

                                    netwns64.sys causing the problem.


                                    When I enable the my wifi, it does nothing on first click. Then when I click it again to enable it, BSOD shows up right away.


                                    I have a Sony Vaio SA with all updated drivers from Sony. I have a intel 6205 wifi card, and I'm running Windows x64 professional.


                                    So, has this problem been solved yet?
