WiFi Driver Bluescreen

Recommended Posts

I installed the Atheros WiFI driver (source:Toshiba website) on my laptop and the installation completed without any error although the driver didn't seem to work as WiFi was still unaccessible as if the driver was not installed so I attempted to install the driver again. This time, my PC bluescreened (well, it's more of a dark-cyan screen in W8) while the driver was being installed. The BS message was "IRQL NOT LESS OR EQUAL" and I've attached the minidumps to this post.

What can I try to get the driver to install successfully?

I would first make sure to uninstall any Atheros drivers and software. If you are trying to install using a Setup application, try instead to point Device Manager to the location of the driver files. See if letting Windows manage the wireless does any better. I personally never install any application for wireless, just the driver.

the Atheros driver wsimdx.sys is very old (2009).
