Is your browser failing to load websites? Learn how to flush your DNS and change your adapter settings to fix this common connectivity bug.

Understanding the DNS Error

When you type a URL into your browser, the Domain Name System (DNS) translates that human-readable address into an IP address. If the "DNS Server Not Responding" error pops up, your device is failing to communicate with this crucial directory.

# Checking Your Connection

Before diving into advanced settings, make sure to restart your router. This simple step resolves the issue 50% of the time.

If this fails, you can follow this excellent YouTube tutorial on flushing DNS or read on for the specific commands.

# How to Flush Your DNS

1. Open the Start menu, type cmd, right-click Command Prompt, and select Run as administrator. 2. Type the following command and press Enter: ipconfig /flushdns 3. Then type: ipconfig /registerdns 4. Finally, release and renew your IP: ipconfig /release ipconfig /renew

# Changing Your DNS Server

Sometimes your ISP's default DNS is down. You can switch to a reliable public DNS like Google or Cloudflare.

Navigate to Network & Internet > Advanced network settings > More network adapter options. Right-click your connection, hit Properties, and edit the IPv4 settings to use 8.8.8.8 as your preferred DNS.
