Windows 10: BSOD L1C63x64.sys driver

Hi, I am getting BSODs and the error message it gives is:

Driver_IRQL_NOT_LESS_OR_EQUAL(L1C63x64.sys)

I believe that is the Qualcomm Atheros Network driver, but mine is up to date to the last Windows8 compatible driver on the Atheros website. This leads me to believe it's a third party program causing the BSODs but I'm not familiar with reading the minidump files. I've attached the dump files and any help would be appreciated. Thanks a lot!

:)

Update Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet Controller (NDIS 6.30) to the latest driver available and see if that helps.

 

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!

 

Hi,

Check out this thread for a similar discussion *Smile
i keep getting crashes since i got w10 driver iqrl not less or equal ( - Windows 10 Forums

 

Hi, thanks for the reply. I have seen that thread, but my Qualcomm Atheros driver is up to date with the latest version compatible with Windows 8.1 (there are no Windows 10 downloads on their website), and I don't have BullGuard installed, so I don't think that thread is too applicable. Thanks though.

 

Your Qualcomm Atheros AR8171/8175 Gigabit Ethernet Controller driver has indeed been flagged. Check for an updated version here.

Your Juniper Network Service driver has also been flagged. Check here for an update to the software or uninstall it for testing purposes.

Hi Boozad,

Thanks for the response. My Qualcomm Atheros AR8171/8175 Gigabit Ethernet Controller driver is the latest one available for Windows 8, since they have nothing for Windows 10 yet.

I've uninstalled all of the Juniper programs to see. Hopefully that solves it. Thanks again!

 

The Qualcomm driver could have been a false positive caused by the Juniper driver, hopefully that's the case. Keep us posted.

 

Hi, i have the same problem that is causing a lot of BSODs every day.

I know that one of the problems is the Qualcomm Atheros drive, but there is not any driver for Windows 10 in the Atheros web site.
I have noticed in other threads, that you have found additional programs that are causing the BSODs.
I hope that you are going to do the same here.

Thanks a lot for your time.
