Symptoms
- Wi-Fi connects successfully but shows “No internet, secured.”
- Occurs on all Wi-Fi networks.
- USB tethering from phone also shows “No internet access.”
- Issue persists across all user accounts.
- Safe Mode with Networking does not resolve the issue.
Network Details
- Wi-Fi adapter: Intel (no warning icons in Device Manager)
- IPv4 address: 192.168.1.2
- DHCP server: 192.168.1.1
- DNS servers: 8.8.8.8, 8.8.4.4
- Connection is assigned a valid local IP (not 169.254.x.x)
Cannot ping:
Router (192.168.1.1)
External IP (8.8.8.8)
Domain names (google.com)
What I’ve Already Tried
- Reset TCP/IP stack, flushed DNS cache, renewed DHCP lease
- Changed DNS servers (Google / Cloudflare)
-Uninstalled and reinstalled Intel network drivers - Updated network drivers
- Tested in Safe Mode with Networking
- Tested across multiple user profiles
- Attempted System Restore (no restore points available)
Additional Info
- Issue started suddenly ~3 days ago.
- No recent antivirus, firewall, VPN, or network software changes.
- No hardware changes.
- Other devices on the same networks work normally.
At this point, this appears to be a Windows networking stack corruption or system-level issue rather than a router or driver problem.
What further diagnostics or recovery steps can be taken without doing a full OS reinstall?
