Hello,

I recently started experiencing increasingly frequent BSODs, mostly associated with downloading, all with the error DRIVER_IRQL_NOT_LESS_OR_EQUAL associated with L1C63x64.sys. Thank you for your help.

Hi,

Your problem is related to Atheros Ethernet adapter driver.

Visit bellow website for updates:
https://www.atheros.cz/atheros-wireless-download.php?chipset=87&system=8

there are 3 x64 bit downloads in total, install the one on top of the page.
To test if driver works try to "overload" you network by downloading anything.
using some download manager or similar.

If BSOD comes back download another driver from the same page and repeat the process.
do the same for all 3 drivers.

If none of these work share your last new 3 BSOD's.
