Seemingly random BSOD - PFN list corrupt

Seeing your reply, I did a deeper search for an appropriate driver based in the PnP DevID:

Code:

USB\VID_0CF3&PID_9271\12345

And got this one ..... Drivers for Atheros AR9271 and Windows 7

Attachment 312106

There is no driver update available to that device.

You have to change the USB network adapter in this situation.

Qualcomm Atheros.

It is always better to use the device from a vendor who develops the driver. TP Link uses the driver from Atheros.

Good stuff. Sorry it couldn't be a simpler fix for you.

I have just had another blue screen, just browsing, PFN list corrupt again, upon restarting windows told me my wireless adapters drivers had not been installed, so i uplugged it, and plugged it back in,and it began working again. I have uploaded the dump via DM log collector. I hadnt had any issues since i last posted!

Edit: I have been using a netgear adapter, instead of TP Link. Again netgear says my drivers are up to date, but in the attached picture, it says 2011, which seems a bit.. old

BSOD caused by WiFi .....

Code:

BugCheck 4E, {9a, 21e8f5, 6, 2}

Probably caused by : nwifi.sys ( nwifi!Dot11FreeSendPacket+93 )

NETGEAR WNDA3100v2 N600 Wireless Dual Band USB Adapter driver is failing.

Code:

fffff880`0ade6fb8  fffff880`03a941e8Unable to load image \SystemRoot\system32\DRIVERS\bcmwlhigh664.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for bcmwlhigh664.sys

Which is old enough.

And you are saying ....

Again netgear says my drivers are up to date

Latest driver available with Netgear is Software Version 2.2.0.3 . Which is ......

Attachment 313464

.... exactly the same driver that you have already installed.

Why they dont have updates, the same story. They marketed the dongle, but the driver is originally developed by Broadcom.

Apparently there is no any program installed that may cause those malfunction to network.

You may do one thing, as the latest BSOD was a stop 0x4E. Test your RAM modules for possible errors. Because failing RAM may cause any error, and stop 0x4E is very common for failing RAM.

Run memtest for at least 8 passes, preferably overnight.

If it start showing errors/red lines, stop testing. A single error is enough to determine that something is going bad there.
