Windows 7: BSOD related to Athrx.sys Atheros Wireless LAN driver

29 Dec 2011   #11

Windows 7 Ultimate

It's a Compaq Presario CQ61. It originally came with Vista but due to a hard drive upgrade, I have since installed 7.

Got that from the site for your computer. Software & Driver Downloads Compaq Presario CQ61-410US Notebook PC - HP Customer Care (United States - English)

Edit: Just download and run the executable, then check if the date is updated to 2010.

Were you able to stop your BSODs with the wireless driver? Do you still need a more up to date driver? Let us know if you are still having problems.

Windows Update

I got this when I updated the adapter via windows update. It took trying to update twice to realize what happened. I had to repair windows 1st (from boot menu). I then updated only the drivers, before trying to get SP1, the computer crashed and woudlnt boot again.

Once again with the athrx.sys BSOD.

Get the drivers from the manufactures website. MS's drivers dont always work with OEMs adapters, which is why you usually have to get them from the site after a windows install.

I dont know if you will encounter this as well, but I also had to use the windows update troubleshooter to repair update before I could get win update working again. (I guess since it bluescreened during an update. I had to do this both times)

Win 7 Enterprise x64

Joined this community just to post on this. I battled this problem for a couple days. This was happening on our Dell Latitude 3440 laptops. Look at your Channel Bandwidth on your wireless router (WAP). When it is configured 20/40MHz, the laptops BSOD within 30 seconds. When configured for only 20MHz, it is completely stable.
It was happening on 5 laptops (all I have at the moment). There is only one driver online as of 12/30/13, so upgrading the driver was a dead end. Atheros' website wasn't helpful either.

Dell/Atheros please fix, I never heard of a WAP causing a laptop to BSOD. Let me know if this was helpful.
