Thank you for your detailed update. I recommend first reviewing the suggestions provided by Q&A Assist, as they already cover the standard troubleshooting steps. The guidance below is intended as additional suggestions to help further narrow down the issue.
Based on what you’ve described (device connected to the internet but unable to sign in), this behavior may be related to a Windows sign-in or authentication issue rather than the network itself. In some recent cases, this may occur after a Windows update or when the system is unable to validate your Microsoft account correctly.
As an additional step, you might try temporarily turning on Airplane mode (or disconnecting from the internet) at the sign-in screen and then attempting to sign in using your account password. This can allow Windows to use cached credentials instead of requiring online authentication and may help you get back into the system.
You can also try selecting “I forgot my PIN” from the sign-in options, even if you normally use one, and complete the verification process using another device. This often forces a fresh authentication with your Microsoft account and can resolve situations where the sign-in token is stuck or corrupted.
If none of these options allow you to sign in, you may consider using System Restore or a repair option to return the system to a previously working state without affecting your personal files.
For further clarification, could you confirm whether you are signing in with a Microsoft account (email) or a local account? This will help determine the most appropriate next steps.
Please let me know how it goes after trying these suggestions and I’ll be glad to assist you further.
