The following link provides a solution to this issue [URL] Some people still have the same issue after applying this fix, but it worked for my setup which is: OS: Windows 7 Ultimate x64 Bit Computer: M6500 Precision laptop Wifi card: Network Driver    Intel® Wireless WiFi Link Driver 
BSOD Occurs. In fact the the following link perfectly describes the issue I'm having: [URL] I have run WinDbg to determine exactly whic driver is playing up: NETw5s64.sys    0xfffff880068a8000    Network Driver    Intel® Wireless WiFi Link Driver    13.0.0.107    Intel Corporation    Intel® Wireless WiFi Link Adapter    15/09/2009 12:40:42    15/09/2009 12:40:42    C:\Windows\system32\DRIVERS\NETw5s64.sys    A       I then downloaded the driver package most suitable R249605 (which actually contained driver netw5s.64.sys. The original BSOD that occurred before I made any updates was :netw5v64.sys). Anyway the same problem arises for either of these drivers for the same device: Network Driver    Intel® Wireless WiFi Link Driver. This is the BSOD info that Windows 7 reported when the system rebooted:   Problem signature:  Problem Event Name:    BlueScreen  OS Version:    6.1.7601.2.1.0.256.1  Locale ID:    2057Additional information about the problem:  BCCode:    a  BCP1:    0000000000000000  BCP2:    0000000000000002  BCP3:    0000000000000000  BCP4:    FFFFF80002C20477  OS Version:    6_1_7601  Service Pack:    1_0  Product:    256_1Files that help describe the problem:  C:\Windows\Minidump\050311-29140-01.dmp  d:\Users\Xanthos\AppData\Local\Temp\WER-77298-0.sysdata.xmlRead our privacy statement online:  [URL] the online privacy statement is not available, please read our privacy statement offline:  C:\Windows\system32\en-US\erofflps.txt So even after having attempted updating the driver for the apparently faulty device driver, I am still seeing the problem. Not really sure where to go from here. I am waiting for Dell to get back in touch, but who knows how long that will take. Also, this fault only occurs when performing a large file copy to or from my Dell laptop to a Macbook Pro. I also ran a check disk on both internal disks. Any help would be appreciated, thanks.
