Hi @stephan in this situation we suggest you try to remove the wireless driver first. After that, try to update BIOS to the latest version. And the last step is to reinstall the wireless driver back. If you have updated your BIOS to the latest version, please follow the recommended troubleshooting steps from the link down below: https://www.intel.com/content/www/us/en/support/articles/000031150/network-and-i-o/wireless-networki...
