Windows 7: Random BSODs when on wireless network

Random BSODs when on wireless network

I just moved and my new internet provider is Comcast. Ever since they set up my modem/router, whenever I use the wireless network (which is preferred/needed) I eventually get a BSOD. Sometimes 3-4x in a couple of hours; the longest has been 1.5 days without - that was until this morning, when it happened again (and it's happened 2-3x since today). The BSOD error message is not always the same, but it only happens when I'm on-line wirelessly. Comcast has put in 3 routers over the last week... I'm sure at this point that it's not the router!

I've run hardware and memory diagnostics, defragged, checked bios, etc etc. I'm about 90% sure it's a wireless network driver conflict but my Device Manager says my drivers are up to date. A couple of the screens have mentioned drivers:
athrx.sys
ndis.sys


So -
1) I keep getting different error messages,
2) the computer seems to be fine, whether I re-boot normally or in safe mode, and
3) it only ever happens when I'm on-line through wireless router. I've been hooked up with an ethernet cable for much of the time the last week to be safe, and I've been on the computer but off-line, working in Word and Excel - no crashes. But when I go back to the wireless network....

I've uploaded the DM log.... Any help in deciphering it is greatly appreciated! I sure hope I'm not killing my computer with all these BSODs!

I can post some of the errors I'm getting, but I've only been copying down the first lines -


mostly - bad pool header stop: 0x00000019

also:
stop: 0x0000007E with athrx.sys listed

Irq not equal.... with ndis.sys listed

PS. I'm wondering if this zip file I created contains what it's supposed to? It seems to just have .dmp files through 10/5....? Please let me know if I need to do something else to provide information needed for my case. I followed the instructions here: Blue Screen of Death (BSOD) Posting Instructions

Welcome to the forum,

You did the right thing but there is a bunch of info missing.

Since we have the older dumps in your first post, can you go to C:\Windows\Minidump and delete the ones that aren't from this month.

Then run the tool again and post it in your next post.

I'm a little worried about your AV choice, but that's another matter.

From the info you did provide, I see your wireless driver getting flagged.

Code:
Unable to load image \SystemRoot\system32\DRIVERS\athrx.sys, Win32 error 0n2
*** WARNING: Unable to verify timestamp for athrx.sys
*** ERROR: Module load completed but symbols could not be loaded for athrx.sys

I see a newer one at Acer,

Your dumps are all over the place and the fact that your AV is also a tune up and optimizer it's likely doing some screwy things to your system.

Thanks, derekimo, I'll re-do the minidump re-upload tomorrow... gotta hit the hay tonight. Thanks for the link to the Acer drivers too - I didn't think to look there. It's the version I have, but it couldn't hurt to uninstall and re-install it from the site.

I'll post the new info tomorrow, and give this another go. Thanks again for the reply.

You're welcome. If it's the same version then they just have different dates for another reason.

That's part of the info that was missing from the upload. Yeah, couldn't hurt trying it though.

Okay, this one seems to have more files in it besides the dmp files. And I cleared out the Sept and older dmp's. I hope this is helpful!

In the meantime, I think I'm going to re-install that Atheros driver.

Thanks!

Yeah, that's a little better. This is how many files besides the dumps that should be in there,

This one is one of the most important,

Let us know how things go after updating that driver.

Well, lol, I crashed right when I came here to read the latest reply! So I guess re-installing the driver didn't do anything. But I am not entirely sure that the install I did - using the setup.exe in the zipped directory from the Acer site - actually replaced the athrx.sys.... It did install another Bluetooth driver, but everything else looks the same.

Anyway, I'm in Safe mode now and I'm going to try this file compiling again. It was weird, when the dm log collector was making the files, it created a folder that had a ton of other files in it, but when it zipped the whole thing at the end, a lot of them disappeared.

I'm going to try dm log collector once more, and if that doesn't work, I'll try the Windows way.

Yeah, much better.

Have you scanned your system for malware?

Your dump files are all over the map but there is a common recurring driver and that's the Athrx.sys.

Can you confirm this is what you are using as AV that's listed in your specs,
