“Driver_irql_not_less_or_equal
(l1c63x64.sys)” BSOD in Windows 10
Hi, today we will talk about an issue that was pretty
persistent on my machine using Windows 10. I searched the internet for a
solution and found various “solutions” which didn’t seem to work since the
Diagnosis was wrong (hence the solution would be wrong). The solution is much
simpler than anybody would expect and it takes about 5 minutes to fix. First of
all we need to clarify what this specific .sys file does. This is a driver and
specifically for an onboard Ethernet Qualcomm Atheros AR8151 PCI-E Gigabit
Ethernet Controller. This is a crappy error which can happen at any moment
(gaming….. especially gaming)
The problem exists with the driver that is used within
Windows 10 repositories (which use the version 2.1.0.16). So, updating the
driver will fix the problem. . So here is a quick and dirty tutorial on how to update the driver.
1)
Download the driver from here
(in case you are wondering I have linked the official Atheros site download
link)
2)
Unzip all the files in a folder in a folder of
your choice (do confirm the filename from the picture and CRC32 numbers to be
safe).
So from this:
You should get this:
3)
Finally let’s install the driver:
i) Type
This PC at your start menu, right click and select Properties
ii)
Select Device Manager
iii)
Under Network adapters select the proper device
(for any of you that have ADD it would be the Qualcomm Atheros AR8151 PCI-E
Gigabit Ethernet Controller), right click it and select Properties
iv)
Select the Driver Tab and click on update
driver.
v)
The great Wizard will appear! Select Browse my
computer for driver software
vi)
Click Browse and go to the folder where you
unzipped your files and select next.
vii)
Your machine will notify you that Windows has
successfully updated your drivers with the following message:
3)iii) and 3)iv) and make sure
that the version number has changed to 2.1.0.26.
Enjoy!
