This module is responsible for managing Wi-Fi connections, and when it stops, you may experience connection drops, slow Wi-Fi, or an inability to connect to networks. The steps below help fix this issue and restore stable wireless connectivity.

Fix WLAN Extensibility Module Has Stopped Unexpectedly

Fix 1: Restart the WLAN AutoConfig Service

Restarting this service often resolves module stoppages.

Fix 2: Run Network Troubleshooters

Windows includes built-in troubleshooters that can detect and fix network issues.

1. Open Settings and go to System, then Troubleshoot, and then go to Other troubleshooters.

2. Run the Network Adapter troubleshooter.

3. Also, run the Internet Connections troubleshooter and follow the instructions.
