To resolve connectivity issues and regain access to your Windows 11 device, you must first verify network adapter settings through the Settings app or Network Status page, then reset your PIN via the Sign-in options menu. If standard methods fail, use the Command Prompt with administrative privileges to clear cached credentials or repair network stacks using specific netsh commands. This guide provides the exact steps for both scenarios to restore full system functionality.
Verifying and Configuring Network Settings
Before attempting complex troubleshooting, ensure that your basic network configuration is correct. Windows 11 manages network adapters through a centralized interface that allows users to view status, change properties, and troubleshoot common errors. Start by opening the
Settings application from the Start menu. Navigate to
Network & internet in the left-hand sidebar. Here, select the active connection type, such as
Wi-Fi or
Ethernet, depending on how your device connects to the internet.
Under the selected connection, click on
Hardware properties or
Properties. Verify that the IP assignment is set to Automatic (DHCP) unless you are using a static IP address provided by your network administrator. If you suspect a temporary glitch, toggle the network adapter off and back on within this menu. For more advanced diagnostics, scroll down to the
Network status section and run the built-in
Network troubleshooter. This tool automatically detects misconfigured DNS settings, incorrect gateway addresses, or disabled adapters.
If the troubleshooter fails to resolve the issue, you may need to manually configure TCP/IP settings. In the same properties window, locate
IP assignment and click
Edit. Ensure that
Automatic (DHCP) is selected. If you require a static IP, enter the correct IP address, subnet mask, default gateway, and DNS servers provided by your ISP or IT department. Incorrect DNS entries are a frequent cause of "no internet" errors even when the physical connection is stable. After making changes, restart your browser or open a command prompt to ping an external server like
8.8.8.8 to confirm connectivity.
For persistent issues, resetting the network stack via Command Prompt can be highly effective. Open
cmd as an administrator. Run the following commands sequentially to flush DNS cache, release IP configurations, and renew leases:
ipconfig /flushdns
ipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ip reset
After executing these commands, restart your computer. This process clears corrupted network states that often persist after driver updates or sudden disconnections. If you are still experiencing difficulties, consider checking if other devices on the same network can connect. If they cannot, the issue likely lies with your router rather than your PC.

Resetting Your PIN in Windows 11
If you have forgotten your Windows Hello PIN, you can reset it directly from the sign-in screen or through the Settings app. The PIN is stored locally on the device and is tied to your Microsoft account or local user profile. To begin, go to
Settings >
Accounts >
Sign-in options. Under the
PIN (Windows Hello) section, click
I forgot my PIN. This option will launch a verification wizard that requires you to sign in with your Microsoft account password.
If you do not have access to your Microsoft account email or phone number, you may need to use alternative recovery methods. Windows 11 attempts to send a verification code to your registered contact information. Enter the code when prompted. Once verified, you will be asked to create a new PIN. Choose a PIN that is easy for you to remember but difficult for others to guess. Avoid sequential numbers or dates associated with personal information.
In cases where the
I forgot my PIN option is grayed out or unresponsive, there may be a corruption in the Trusted Platform Module (TPM) data or the credential provider service. You can attempt to remove the existing PIN registry keys manually, but this carries risks. A safer approach is to boot into Safe Mode. Restart your PC while holding the
Shift key, then navigate to
Troubleshoot >
Advanced options >
Startup Settings >
Restart. Select
Safe Mode from the list. Once in Safe Mode, try accessing the Sign-in options again. If the issue persists, check for pending Windows updates that might contain fixes for authentication bugs. For guidance on recovering access after major system changes, refer to
Can't Login After Windows 11 Update - Troubleshooting Guide.
Another method involves using the Command Prompt if you have administrative access. You can delete the NGC folder which stores Windows Hello credentials. Press
Win + R, type
%windir%\System32\Microsoft\Protect, and press Enter. Delete the contents of the
NGC subfolder. Then, restart your computer. Upon reboot, Windows will prompt you to set up a new PIN. Note that this action removes all biometric data linked to the current session, so you will need to re-enroll fingerprints or facial recognition data afterward. Always ensure you have a strong password backed up before performing deep system resets.
Frequently Asked Questions
Why does my network show limited connectivity?
Limited connectivity usually indicates that your device has obtained an IP address but cannot reach the internet gateway. This is often caused by incorrect DNS settings or a malfunctioning DHCP server. Try switching to public DNS servers like Google's 8.8.8.8 or Cloudflare's 1.1.1.1 to bypass local resolver issues.
Can I reset my PIN without knowing my Microsoft account password?
No, you cannot reset a Microsoft-linked PIN without verifying your identity through the associated account. If you have lost access to the email or phone number, you must recover the account through Microsoft's online support channels first. Local accounts allow PIN resets only if you have previously set up security questions or a password recovery key.
What should I do if the network troubleshooter finds no problems?
If the built-in troubleshooter reports no issues, the problem may lie with outdated network drivers or hardware faults. Visit your PC manufacturer’s website to download the latest LAN or Wi-Fi drivers. Alternatively, disable and re-enable the network adapter in Device Manager to force a driver reload.
Is it safe to delete the NGC folder to fix PIN issues?
Yes, deleting the NGC folder is a supported troubleshooting step for Windows Hello errors. However, it removes all saved biometric data and the current PIN, requiring you to set them up again. Ensure you know your account password before proceeding, as you will need it to authenticate the new setup process.
How do I check if my firewall is blocking network access?
Open
Windows Security and navigate to
Firewall & network protection. Check if any rules are explicitly blocking applications or ports required for your network services. Temporarily disabling the firewall can help identify if it is the cause of the connectivity loss, but remember to re-enable it immediately after testing.
