BSOD - driver_irql_not_less_or_equal (l1c63x64.sys)

Hi Seung,

Sorry for the inconvenience caused by BSOD - driver_irql_not_less_or_equal (l1c63x64.sys).

Please let us know the make/model of your computer.

The L1C63x64.sys is the Atheros LAN driver and I would suggest to uninstall and reinstall the Atheros LAN driver but install the latest Atheros LAN driver by visiting the manufacture's website and avoid using any LAN driver available though Windows Update.

However the problem could also be with any VPN software and other software so make sure you have the latest version of each of these software.

If the errors continue uninstall the VPN software and check if the issue persist.

Hope this helps. Get back to us for further queries for BSOD - driver_irql_not_less_or_equal (l1c63x64.sys). We are happy to help!
