How to fix the network problem in macOS Sequoia

If you have a Mac later than 2018 and after updating to the latest version of macOS (such as macOS Sequoia or Sonoma) your Wi-Fi connection has stopped working correctly, you are not alone. In recent months, hundreds of users have reported wireless connection problems after installing the update. Although many suspect the operating system, the most common cause is not Apple, but a conflict with the ESET antivirus.

At iRepairs we explain how to resolve this fault step by step so that you can browse again without interruptions or loss of speed.

How to fix Wi-Fi problems caused by ESET on macOS

1. Disable the ESET network filter

The ESET antivirus includes a protection system that filters network traffic to improve security. However, after the latest macOS updates, this filter can interfere with the Wi-Fi connection and cause the machine not to detect networks correctly.

To check this, you can temporarily disable the network filter and verify whether the connection improves:

1. Open System Preferences > Network.
2. Select the Filters tab and locate “ESET Network”.
3. Click the “–” icon to remove or disable the filter temporarily.

Once done, try to reconnect to your Wi-Fi network. If the connection works normally again, you will have identified the source of the problem.

2. Uninstall and reinstall ESET Antivirus

If the error persists, the most advisable thing is to completely uninstall ESET and reinstall the latest version compatible with your operating system. This way, you can make sure that the software is correctly integrated with macOS 2025.

1. Open the Applications folder and look for ESET Antivirus.
2. Right-click on the application and select “Show Package Contents”.
3. Go to Contents > Helpers and run the uninstaller.
4. Restart your Mac and check whether the Wi-Fi connection works again.

Once you confirm that the problem has disappeared, you can reinstall ESET from its official page, making sure to download the most recent version (compatible with macOS 14 or 15, depending on the model).

3. Other useful checks

• Update your version of macOS from Settings > General > Software Update.
• Restart the router and try to connect to another network to rule out external faults.
• If you use a third-party VPN or firewall, disable them temporarily to run tests.
