Sometimes, the problem isn't your Mac or Wi-Fi, but the DNS (도메인 이름 시스템) your ISP uses. You can switch to faster, more reliable public DNS servers:

  1. System Settings > Network > Wi-Fi > Details > DNS.
  2. 추가 :

4. Run macOS Wireless Diagnostics

If you're experiencing internet connection problems in macOS Ventura, Apple’s built-in Wireless Diagnostics tool can help identify the root cause. Here’s how to use it:

  1. Hold the Option key and click the Wi-Fi icon in the menu bar.

  5. Window > Performance to monitor signal quality, noise, and data rate.

Wireless Diagnostics will also generate a detailed report (stored in /var/tmp) which you can review or send to support if needed.

5. Disable VPNs, Firewalls, or Third-Party Security Apps

If you use apps like NordVPN, ProtonVPN, Little Snitch, or LuLu, they could be interfering with Ventura's internet traffic.

  1. Temporarily disable them.
  2. Test internet speed and stability.
  3. If it improves, try updating or replacing the app, or adjusting its filtering settings.
