Hello everyone,

I've quite a weird situation here. Recently I switched radio from Broadcom to Atheros chipset and now I can easily make my computer crash with Blue Screen Of Death by applying a constant load on it. Previously I were using an ASUS WL500gP with stock radio but now I switched to ALIX board with TP-LINK TL-WN560G card.  And now with running uTorrent and speed around 10Mbit/s it's just a matter of time to get a BSOD.

The errors codes are 0xa and 0xd1. Windows Debugging Tools blames netw5v64.sys for crash and it stands for a component from Intel WiFi driver. I tried different WiFi drivers with the same result.

So far I tend to blame the either netw5v64.sys or madwifi.

Can someone with similar setup that involves Intel WiFi card on Windows x64 that is served by a OpenWRT router with Atheros card confirm it or deny it?

Changed the radio card to TL-WN861N that runs under ath9k driver. But unfortunately system still crashes.

Tomorrow I'll try to test it under another Intel 4965AGN card.

Well it runs perferctly for about 2 hours now, so I assume I should pay a visit to service center.

Well, I was a little bit too quick in writing back. After 4 hours it crashed.

So far I tried it on two different Thinkpads T61, different radio cards (TL-WN560G and TL-WN861N) and different boards for OpenWRT (ASUS WL500gPv1 and PCEngines Alix 6b2) with the same results - a STOP Error of 0x0000000A or 0x000000D1. Leaving all the hardware components involved in transmission.

The only thing left are drivers and most likely the Intel driver is causing it, because I tried both madwifi on TL-WN560G and ath9k on TL-WN861N with the same result. Actually it might be wrong assumption, because I believe madwifi and ath9k might share some code.

Does anyone have any ideas what to test more? And how to submit this case to either Intel or Lenovo?

Hi
I never had such problem with my intel 3945 and 2945 wifi cards and my WL-500gP atheros wifi.
Even if there might be a problem in the madwifi driver, the windows laptop shouldn't bluescreen. So I would say that the main problem is on the laptop side (and not the router).

Yeah, zorxd I would think so too. But there's quite unuasual trend here.

Install an atheros card and observe BSOD, swap it with Broadcom card and everything is working.

In any case, I've already submitted a case to Customer Support Service and they're waiting me with this notebook. I hope we will find out the true cause.

Well

Technician from service center thinks that overheating might be causing such behavoir and I've got my cleaned notebook back to test it.
