Hello all

 

You've helped me before with a similar issue with uTorrent (now using BitComet which is much better). 

 

Our of the blue (pardon the pun), I've encountered the BSoD again. All logs and dump file attached. The last installed files where Fortigate client and Windows updates. 

 

What I've discovered is if I physically remove the Wireless card from the PC, Windows 7 boots up fine (I just don't have interenet). I'm assuming it's something to do with the athr.sys file or wireless files? 

 

Any insight into the logs I have attached would certainly help and I'll report back on any solution(s).

Hi

 

Your BSOD issue seems to be caused by the WiFi driver.

BugCheck D1, {4, 2, 0, 8bec65fc}

Unable to load image \SystemRoot\system32\DRIVERS\athr.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for athr.sys
*** ERROR: Module load completed but symbols could not be loaded for athr.sys
Probably caused by : athr.sys ( athr+3a5c1 )

What is the make and model of your TP-Link adapter ?.

Hi Anshad, 

 

The model is TL-WN781ND version 1. 

 

I think the issue is now resolved. I renamed the athr.sys to athr.sys.old and reinstalled the latest driver from the TP-Link website. 

 

I wonder why or how it got corrupted ... 

 

Thanks, Matt

Glad to hear that  :thumbup2: .

It is hard to say but i assume a Windows update may braked the compatibility between the WiFi driver and Windows.
