Hi MiyuGZ,
Welcome to Microsoft Community.
It sounds like the wireless adapter may have been disabled or could be encountering a driver issue. Here are a few steps to try and resolve the issue:
- Run Windows Network Troubleshooter:
- Select Start and type settings. Select Settings > System > Troubleshoot.
- Select Other Troubleshooters.
- Select Network Adapter > Run. Launch Network Troubleshooter
- Follow the steps in the troubleshooter and see if that fixes the problem.
- Force restart your Surface:
Close any open programs and then press and hold the power button until the logo screen appears (about 20 seconds). See Force a shutdown and restart your Surface for more info.
- Manually update Surface drivers and firmware: Download drivers and firmware for Surface - Microsoft Support
- Run the Surface Diagnostic Toolkit: Fix common Surface problems using the Surface app and Surface Diagnostic Toolkit - Microsoft Support
- As a last resort, If you've tried basic troubleshooting options, you may need to restore or reset your Surface. If the issue occurs after a reset, then the root cause is very likely hardware related. Restore or reset Surface for Windows - Microsoft Support
I hope this helps. If there is anything not clear, please do not hesitate to let me know.
Your Sincerely
