Network & DNS Troubleshooting

Step-by-step guide to diagnose internet drops, flush the DNS cache, and restore adapter stability.

1. Flush DNS and Reset IP Configuration

Corrupted local DNS resolver caches often cause website loading errors and connection timeouts. Open Command Prompt or PowerShell as administrator and execute the following commands:

ipconfig /flushdns

ipconfig /release

ipconfig /renew

2. Reset TCP/IP Stack

If your network stack is corrupted due to malware or misconfigured software, reset it completely using the netsh utility:

netsh int ip reset

netsh winsock reset

3. Change to Public DNS Servers

If your ISP's DNS servers are unstable, manually switch your adapter settings to reliable public alternatives like Cloudflare or Google:

Cloudflare: 1.1.1.1 / 1.0.0.1
Google: 8.8.8.8 / 8.8.4.4
