WLAN AutoConfig Service Failed to Start (Error 1068)

What is WIFI-AUTOPREP-FAIL?

WLAN AutoConfig Service Failed to Start (Error 1068) is a high-severity network adapter issue. The WLAN AutoConfig service (Wlansvc) failed to start, causing all wireless network adapters to become unresponsive and preventing the PC from scanning or connecting to Wi-Fi networks. Typical causes include corrupt ndis.sys driver, disabled dependency services (e.g. Native WiFi Filter) and corrupt system registry. See the troubleshooting steps below for the fix.

Common Causes

• Corrupt ndis.sys driver
• Disabled dependency services (e.g. Native WiFi Filter)
• Corrupt system registry

Step-by-Step Fix Guide

• 1
  Start WLAN AutoConfig manually

  Starting the service manually tests if it can run. If it fails with dependencies error, check Native WiFi Filter.

• 2
  Reset network stack using Command Prompt

  Resetting the IP/Winsock stacks clears out bad configuration that blocks WLAN startup.

• 3
  Enable WLAN dependency services in Services.msc

  This step, "Enable WLAN dependency services in Services.msc", specifically rules out disabled dependency services (e.g. Native WiFi Filter).
