Dear Forum.
I'am trying to automate a Test with NetSH and a BE200 Card.
Sadly the whole Win11 System crashes.
StopCode: 0x0000007e
Arguments:
Arg1: ffffffffc0000420, The exception code that was not handled
Arg2: fffff803423f72fe, The address that the exception occurred at
Arg3: ffffda842cdda4c8, Exception Record Address
Arg4: ffffda842cdd9ce0, Context Record Address
EXCEPTION_RECORD: ffffda842cdda4c8 -- (.exr 0xffffda842cdda4c8)
ExceptionAddress: fffff803423f72fe (NetAdapterCx!BufferPool::~BufferPool+0x0000000000000012)
ExceptionCode: c0000420 (Assertion failure)
ExceptionFlags: 00000000
NumberParameters: 0
Assertion minio\netcx\bm\bufferpool.cpp(9): IsFull()
Does anyone have a solution for that problem or is there any kind of Information about the error?
Help is greatly appreciated.
Thx in advance.

can you try the driver in this link.
Intel(R) Wi-Fi 7 BE200 320MHz
Wireless Wifi/Bluetooth software Version 23.60.0.10 WHQL
hey there FM
Stop Code 0x0000007e is a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED error, which is a very common bug check that indicates the system encountered an unhandled exception generated by a system thread.
exception code 0xc0000420 denotes an assertion failure. This could be due to a bug in the driver or firmware of the BE200 card, or an incompatibility with Windows 11. The specific assertion failure in minio\netcx\bm\bufferpool.cpp suggests there might be an issue with the buffer pool within the network driver that's not being properly handled.
Here are some steps you can take to troubleshoot and potentially resolve the issue:
- Update your wireless driver especially those related to the BE200 card, are up to date.
- Make sure your Windows 11 system is fully updated, as Microsoft frequently releases updates that can fix known bugs and compatibility issues.
- Run a memory check on your system. Faulty RAM can sometimes cause these types of errors. You can use Windows Memory Diagnostic or a third-party tool like MemTest86.
- Use the System File Checker tool to repair missing or corrupted system files. Run sfc /scannow in the Command Prompt (admin).
- Use the Deployment Imaging Service and Management Tool (DISM) with the command DISM /Online /Cleanup-Image /RestoreHealth.
I hope this helps, and you're able to resolve the system crash issue soon.

In my office, we've been experiencing the same issue since November 2024. We reported it to Dell Inc. in January 2025 (both local and global teams), but they still haven't identified the root cause. I’ve sent them numerous log files and shared detailed information.
Based on my own investigation, we strongly believe the root cause is the Intel® Wi-Fi 7 BE200 320MHz card, which may have compatibility issues with our Wireless LAN network that only supports Wi-Fi 6 (2.4GHz and 5GHz).
Why do I believe the Wi-Fi 7 WLAN card is the issue? Because we have more than 30 laptop models, and only the ones equipped with the Intel® Wi-Fi 7 BE200 320MHz are experiencing BSOD 0x0000007E (0xFFFFFFFFC0000420).
@FM9, you might want to try selecting 802.11AX and disabling the 6GHz band in the Wi-Fi adapter settings.
