Resetting Windows Network Settings

Corrupted network stack components cause issues like 'No Internet' despite being connected, inability to reach specific sites, or slow DNS resolution. A network stack reset often resolves these. Open an elevated command prompt and run these commands in order: 'netsh winsock reset', 'netsh int ip reset', 'ipconfig /release', 'ipconfig /flushdns', 'ipconfig /renew'. Reboot after all commands complete. For VPN-related network issues, also run 'netsh advfirewall reset' to reset the Windows firewall to defaults — some VPN clients leave orphaned rules. If a specific website is unreachable but others work, test with 'nslookup sitename.com 8.8.8.8' to check if the issue is DNS-related. Changing the DNS server (Settings > Network > DNS) to 8.8.8.8 or 1.1.1.1 can bypass ISP DNS problems.
