📎 AI Summary:
The thread concerns WLAN AutoConfig failing to start in Windows 11 after an upgrade to build 29558, with the problem continuing in build 29680; RasMan also crashes, while the Wi-Fi adapter works in another Windows installation. Service settings and system-file verification revealed no obvious fault, so the replies treat the matching access-violation crashes and running Killer background services as clues, not proof of a cause, and suggest temporarily stopping those services to test for an interaction. The discussion remains calm and methodical, with no confirmed fix yet.

Something wrong with the Wi-Fi settings in my installation of Windows. The Wlansvc service (WLAN AutoConfig) cannot start.
1. Wi-Fi Adapter: Killer(R) Wi-Fi 6E AX1675i 160MHz Wireless Network Adapter (211NGW)
2. OS: Windows 11 build 29680.
3. All necessary drivers are installed.
4. Wi-Fi adapter is ON (obviously).
5. Wi-Fi adapter itself is working fine. When I boot into another Windows (Live CD) then I can successfully connect to the Wi-Fi network.

The Windows Event Log shows these entries:

Since the Wi-Fi adapter works fine in a Live CD, the issue seems more likely to be related to Windows than the hardware. Have you tried running sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth to check for corrupted system files? It may also help to check the WLAN AutoConfig service dependencies and Event Viewer logs for more details about the msvcrt.dll crash.
