my computer is x201i 3249 cbc
last 2 weeks my computer suffered from blue screen
after counselling i found out that it is due to my wireless driver's not updated
here is the conclusion (after I sent my dmp file to the helper):
The DRIVER_IRQL_NOT_LESS_OR_EQUAL bug check has a value of 0x000000D1. This indicates that a kernel-mode driver attempted to access pageable memory at a process IRQL that was too high.
On every occasion NETwNs32.sys is being shown as the problem.
Loaded symbol image file: NETwNs32.sys
Image path: \SystemRoot\system32\DRIVERS\NETwNs32.sys

I have looked on the manufacturers website and there is an updated driver for you wireless card :
Yours is dated oct 2010 as above so depending on what card it is the newest dates are below:
Intel WIFI and WIMax 6250 - driver is 17 dec 2010
Intel Wireless Lan (bg, abg, abgn) - driver is 19 nov 2010
Thinkpad 802.11bgn Wireless LAN mini pci express adapter II - driver is 30 nov 2010
the message mainly says that my driver date is oct 18 and there are newer ones now and i also think it shall be the solution
so I went to lenove and downloaded this one:
we can clearly see that its release date is 2010/11/9
then here comes the installation and what i want to ask:
first i uninstalled my older wireless driver using control panel
then i installed the newer one
but when i check it in control panel, unfortunately it still shows "driver date: 2010/10/8" which is the same as older one
no matter what new drivers i intalled, they all showed 10/8 in the control panel whatever the actual release date they have
so the blue screen just keeps troubling me
may you tell me what'sthe reason and the solution?
put an end to this plz...(a new computer but almost crashs at least once a day)
thank you all

Hello mate, When you look for a driver check the version not the release date. I think you might try to install the previous version of the driver if the last one is not working properly.
I give you the link there : http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/6mws20ww.exe
Also what verion of Access connections do you use ?
You should try to install Power management driver a s well : http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-4GXPEG

I changed my driver to the link you gave
but just then comes up another blue screen and i checked the dmp file found it still the problem with my driver
what am i supposed to do now? to try older and older drivers?..

programs, thinkvantage, system update. if you don't already have it download it from the link and run it. it will give you a list of updated drivers for your system. don't just download and install all of them at once, do it one at a time and reboot after each one. if there is one for your bios, do that one first.

Backup and do a factory reset (make recovery CD's if you have not done this yet...)
Sometimes the weeks worth of effort you invest in trying to fix individual errors just isn't worth it in the end, considering you could have everything back up and running in an hour.

but i don't know whether this is because that i bought my computer in one country and use it now in another so that there
comes up some compatibility issues
i remember that when used in the country i bought it everything's ok but the bluescreen occured almost the first day i came here
such problem may not be able to be solved just by factory reinstall right?
