5 Ways to Automatically Turn Off Wi-Fi When Ethernet Is Connected
Stop dual connections by disabling Wi-Fi automatically whenever a LAN cable is plugged in.
Overview
Running Wi-Fi and Ethernet at once can cause routing quirks. Many people prefer Wi-Fi to switch off automatically when a wired connection is available. This guide covers the built-in setting and helper tools.
Key Takeaways
- Some adapters have a built-in "disable on wired connect" option.
- Interface metrics can prefer Ethernet without disabling Wi-Fi.
- Free tools can auto-toggle Wi-Fi based on Ethernet state.
- Choose based on whether you want Wi-Fi off or just deprioritized.
Method 1: Adapter Setting (WLAN AutoSwitch)
1. Open Device Manager > Network adapters > your Wi-Fi adapter > Properties > Advanced.
2. Look for a setting like "Disable Upon Wired Connect" (Intel) or "WLAN AutoSwitch".
3. Set it to Enabled.
4. Wi-Fi now turns off when Ethernet is connected.
Method 2: Prefer Ethernet via Metrics
1. If you only want Ethernet preferred (not Wi-Fi off), set a lower interface metric on Ethernet.
2. ncpa.cpl > adapter > IPv4 > Advanced > untick Automatic metric, set Ethernet lower.
3. Windows then uses Ethernet while leaving Wi-Fi available.
Method 3: Free Tools
Note: Download tools like WirelessAutoSwitch only from their official sources.
1. Install a tool such as WirelessAutoSwitch or a WLAN Manager.
2. Configure it to disable Wi-Fi when a specified Ethernet adapter is up.
3. It re-enables Wi-Fi when the cable is unplugged.
Troubleshooting
Problem: No "Disable on wired connect" option.
Solution: Not all adapters expose it — update the driver, or use a tool/metrics approach instead.
Problem: Wi-Fi doesn’t come back.
Solution: Ensure the tool re-enables it on unplug, or turn Wi-Fi on manually; check the adapter setting.
Problem: Both still active.
Solution: Use interface metrics to prefer Ethernet if you don’t want to fully disable Wi-Fi.
Problem: Tool flagged by antivirus.
Solution: Download from the official source and verify; network togglers are sometimes false-flagged.
Conclusion
If your Wi-Fi adapter has a "disable on wired connect" option, that’s the cleanest fix. Otherwise, prefer Ethernet via interface metrics, or use a helper tool to auto-toggle Wi-Fi based on the LAN cable state.
