Deel 1. Why Is the Internet so Bad on My macOS Ventura?

Why do I have internet connection problems in macOS Ventura? Experiencing slow or unstable internet on Mac can be frustrating, especially when other devices work fine. There are several common causes, ranging from software bugs and misconfigurations to interference and hardware limitations.

  1. DNS or Network Configuration Issues
  2. Wi-Fi Interference or Weak Signal
  3. Background Processes & iCloud Sync
  4. Software Bugs or Updates
  5. VPNs or Firewalls
  6. PRAM, SMC, or Network Reset Needed

Deel 2. How to Fix macOS Ventura WiFi & Internet Connection Problems?

How to fix internet connection problems in macOS Ventura? Here are the most effective steps to restore a fast and stable connection on your Mac:

1. Restart Your Mac and Router

This may sound simple, but restarting can fix temporary glitches in network configuration. This clears temporary IP conflicts, resets router cache, and allows your Mac to reconnect cleanly to the network.

  • Start je Mac opnieuw op: Click the Apple menu > Restart.
  • Power cycle your router: Unplug it for 30 seconds, then plug it back in.

2. Forget and Reconnect to Wi-Fi Network

To fix internet connection problems in macOS Ventura, one thing you should do is to disconnect the WiFi connection and reconnect it later.

  1. Ga naar System Settings > Network > Wi-Fi.
  2. Klik op de Details button next to your network.
  3. Kies Vergeet dit netwerk, then reconnect by entering the password again.

This clears any corrupted settings that may have saved incorrectly, especially after system updates.

3. Use Custom DNS Servers

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

  1. System Settings > Network > Wi-Fi > Details > DNS.
  2. Voeg toe:
  • Google-DNS: 8.8.8.8, 8.8.4.4
  • Cloudflare DNS: 1.1.1.1, 1.0.0.1

These servers often respond faster than your ISP’s default, improving browsing speed and reliability.

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.
  2. Selecteren 'Open Wireless Diagnostics' In de vervolgkeuzelijst.
  3. When the assistant opens, you can either run the full diagnostic scan or skip it and go to the menu bar.
  4. Klik Window > Scan to view nearby networks and suggested channels.
  5. Klik Window > Performance to monitor signal quality, noise, and data rate.

These tools can detect issues like weak signal strength, overlapping channels, and network interference—all common reasons behind internet connection problems in macOS Ventura. 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.

6. Reduce Network Load from Background Services

A common but overlooked cause of internet connection problems in macOS Ventura is excessive background activity. Features like iCloud syncing, automatic app updates, and system services can silently consume bandwidth, slowing down your network.

To reduce this network load:

  1. Pause iCloud syncing temporarily via System Settings > Apple ID > iCloud Drive.
  2. Uitschakelen Ververs apps op achtergrond for unnecessary apps.
  3. Open Activity Monitor > Network tab to find which apps are using bandwidth and quit high-usage processes.

7. Change Wi-Fi Channels and Frequency Bands

If you're in an apartment or crowded Wi-Fi zone, interference can slow down your connection:

  1. Log into your router (usually via 192.168.1.1 in een browser).
  2. Schakel over naar een 5 GHz-band, which is faster and less crowded than 2.4GHz.
  3. Use Apple’s Wireless Diagnostics > Scan window to find the least congested channels and change to those manually in your router settings.

8. Create a New Network Location

This creates a clean profile for your connection:

  1. Ga naar System Settings > Network.
  2. Click the drop-down menu next to Locatiedan Edit Locations > + (Add).
  3. Name it something like "New WiFi Profile" and click Klaar .
  4. Reconnect to your Wi-Fi and test the performance.
