How to fix rtwlane6.sys Blue Screen error in Windows?

Issue: I have recently purchased a new laptop with pre-installed Windows on it. But recently I have been getting blue screens a few times a day all the time. The stop code is marked with SYSTEM_THREAD_EXCEPTION_NOT_HANDLED with “what failed” being rtwlane6.sys. My computer shouldn't be experiencing these problems, considering it's brand new.

Solved Answer

Windows machines are known for their powerful performance and are often preferred by users. The latest versions of Windows, such as 10 and 11, come with polished user interfaces, improved features, and functionality. However, even with all these benefits, users may still experience Blue Screen of Death errors caused by files such as rtwlane6.sys, irrespective of their computer and Windows version.

BSOD errors, also known as stop errors, can be very frustrating and inconvenient. They can occur suddenly, causing an immediate system restart, disrupting important tasks, or causing loss of unsaved work. Despite this, the forced restarts serve a vital purpose in the Windows environment.

If the system would not reboot in the case of a stop error, it could be subjected to irreparable damage. When a BSOD occurs, Windows typically performs troubleshooting steps automatically and restarts the system. However, persistent blue screens could indicate more serious underlying issues that require immediate attention. It is essential to address such errors to prevent further damage and ensure the smooth functioning of the system.

Rtwlane6.sys uses the SYS file extension, which is considered Win64 EXE file, referring to the driver associated with it. In this case, the file is related to the Realtek Wireless LAN driver, which is likely to cause these crashes. In fact, most Blue Screen of Death errors is caused by drivers, although it is not a rule.
