  2. Release and Renew Your IP Address:

    • Open Command Prompt (Windows) or Terminal (macOS). This is where you'll enter commands to manage your network settings.
    • Type ipconfig /release (Windows) or sudo dhcpclient -n en0 (macOS) and press Enter. This releases your current IP address.
    • Type ipconfig /renew (Windows) or sudo dhcpclient -n en0 (macOS) and press Enter. This requests a new IP address from your router.
    • Restart your computer. This ensures that the new IP address is properly applied.
    • Explanation: Releasing and renewing your IP address forces your computer to request a new IP address from your router. This can resolve IP address conflicts or other network configuration issues.

  3. Flush DNS Cache:

    • Open Command Prompt (Windows) or Terminal (macOS).
    • Type ipconfig /flushdns (Windows) or sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder (macOS) and press Enter.
    • Explanation: Flushing your DNS cache clears out any outdated or corrupted DNS entries, forcing your computer to retrieve the latest DNS information from the DNS server. This can resolve issues where Chrome is unable to resolve domain names correctly.

  4. Change DNS Servers:

    • Access your network adapter settings. On Windows, you can find this in the Control Panel under "Network and Sharing Center." On macOS, you can find it in System Preferences under "Network."
    • Select your network adapter and click "Properties" (Windows) or "Advanced" (macOS).
    • Find "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties" (Windows) or "TCP/IP" tab (macOS).
    • Select "Use the following DNS server addresses."
    • Enter the following DNS server addresses:
      • Preferred DNS server: 8.8.8.8 (Google Public DNS)
      • Alternate DNS server: 8.8.4.4 (Google Public DNS)
    • Click "OK" to save your changes.
    • Explanation: Google Public DNS servers are reliable and fast. Switching to these servers can resolve DNS-related issues that might be causing the "Err_Network_Changed" error. Other popular options include Cloudflare's DNS (1.1.1.1 and 1.0.0.1).

  5. Update Network Adapter Drivers:

    • Open Device Manager (Windows). You can search for it in the Start menu.
    • Expand "Network adapters."
    • Right-click on your network adapter and select "Update driver."
    • Choose "Search automatically for drivers."
    • If Windows doesn't find a new driver, visit the manufacturer's website and download the latest driver manually.
    • Explanation: Outdated or corrupted network adapter drivers can cause connectivity problems. Updating to the latest drivers can resolve these issues.

  6. Disable Proxy Server:

    • Open Chrome settings. Click on the three dots in the top-right corner and select "Settings."
    • Search for "proxy" and click on "Open your computer's proxy settings."
    • Ensure that "Automatically detect settings" is enabled and that "Use a proxy server" is disabled.
    • Explanation: If you're not intentionally using a proxy server, it's best to disable it. A misconfigured proxy server can interfere with Chrome's ability to connect to the internet.

  7. Disable VPN and Antivirus Software (Temporarily):

    • Temporarily disable your VPN and antivirus software to see if they are interfering with your network connection.
    • If disabling these programs resolves the issue, you may need to adjust their settings or consider using different software.
