  • 📁 SecurityI/O Interface Security
  • 📁 BootNetwork Boot (rare, but it does happen)
⚠️ Warning: Changing incorrect BIOS settings may cause your laptop to become unstable. If you're unsure, take a photo of your current settings before making any changes.

If the adapter still does not appear after being enabled in BIOS, this may indicate:

  • 🔌 Problems connecting the module (reconnect the antennas or the adapter itself if you disassembled the laptop).
  • 💥 Wi-Fi module failure (replacement required).

5. Diagnosing connection problems

If the adapter is enabled but networks are not showing up or the connection keeps dropping, try the following steps:

Checking the WLAN AutoConfig service

This service is responsible for managing wireless networks. To restart it:

  1. Click Win + R, enter services.msc.
  2. Find a service WLAN AutoConfiguration (WLAN AutoConfig).
