How to fix
Rtwlane.sys Blue Screen error
on Windows

Hello. My Windows operating system keeps crashing and displays rtwlane.sys Blue Screen error at least once a day. I cannot seem to find the solution, so would appreciate any tips on how to fix it.

Windows is one of the most popular operating systems created by Microsoft. It is user-friendly and has many customization options. But that sometimes can bring problems like software or hardware incompatibility. The operating system has a built-in troubleshooter designed to quickly locate various problems, but sometimes they cannot prevent serious system errors.

Windows has an error called the Blue Screen of Death.[ref en-1] It is generally caused by problems with a computer’s hardware or drivers. The rtwlane.sys BSOD is something users come across, and it is not a fun experience. Some users were able to use their machine after, but the error keeps crashing their system almost daily and they cannot seem to stop it.

Realtek PCIE NDIS Driver 47261 20277 files such as rtwlane.sys utilize the SYS file extension,[ref en-2] which is considered a Win64 EXE (driver) file. The first version of rtwlane.sys was released for the Windows 8 OS, and there are a number of reasons why users could be encountering issues with it. These types of rtwlane.sys errors can be caused by hardware problems, outdated firmware, corrupt drivers,[ref en-3] or other software-related issues. Some of these errors include:

rtwlane.sys failed to load.

Windows failed to start - rtwlane.sys.

The file rtwlane.sys is missing or corrupt.

rtwlane.sys could not be found.

Normally, this error is accompanied by the code "DRIVER_IRQL_NOT_LESS_OR_EQUAL". The system file might have something to do with the Realtek PCIE Wireless LAN PCI-E NIC driver.

Going through all the possible solutions could take a while, so you can try using an automatic solution [d1] - the repair tool that can identify the damaged system components, fix BSODs, and registry issues potentially saving you from having to reinstall Windows completely.
