Hi, newbie and would appreciate some help.
I have a toshiba satellite r830 with atheros 9002wb wifi card with Win 8.1 pro and sandisk 256 ultra ssd.
For the past 2 days my laptop has been crashing with BSOD with message system handling exception error athwbx.sys file mentioned as the cause. First I refreshed the installation. Then reinstalled the entire OS from scratch. Similar error immediately after reinstalling.
Then changed RAM from another laptop. Same result. Then swapped the SSD to a HDD and reinstalled the OS from scratch on the HDD with the same error cropping up within seconds.
Finally I put the SSD back in reinstalled the OS again and this time uninstalled the atheros driver and connected using ethernet. No problems until the system updated itself and reinstalled the atheros driver from the windows update. It promptly crashed again.
At the moment I have disabled windows update and atheros driver is uninstalled and the laptop works on ethernet.
No antivirus on the system other than windows defender. Fresh install no programs installed.
I am out of ideas other than swapping the atheros card. However I have read that Toshiba has disabled this in the bios. Any solution would be very welcome.
