Wired Connection Priority: How to Switch Windows 10 from Wi-Fi to LAN

Many users encounter a situation where a laptop or PC with a wireless module installed continues to use unstable Wi-Fi, even with an Ethernet cable plugged into the port. This occurs because the operating system, by default, may incorrectly prioritize network interfaces. As a result, despite a fast wired connection, traffic is routed through the wireless network, reducing speed and increasing ping in games.

In Windows 10, the switching mechanism is based on interface metrics, but automatic settings sometimes fail. To force the system to use a LAN connection, you need to manually change the adapter settings. This doesn't require installing third-party software and can be resolved using the built-in system tools in a few minutes.

It's important to understand that simply physically connecting a cable doesn't always break the Wi-Fi connection. The operating system can keep both channels active, choosing the one it deems more reliable based on its internal algorithms. Our task is to explicitly indicate this. Windows, that a wired network is preferred.

⚠️ Warning: Changing the interface metric affects the routing table. If you are using complex corporate networks with static IP addresses, make sure you have access to the router settings or have received permission from your system administrator.

How network priorities work in Windows

operating system Windows 10 Uses a so-called "interface metric" to determine the priority of network connections. The lower the metric value, the higher the priority of the connection. By default, the system attempts to automatically assign these values ​​based on connection speed, but often errs in favor of the wireless module.

When you connect the cable, network adapter receives an IP address, but traffic may still go through Wi-Fi if its metric is lower (i.e., the priority is higher). This is especially noticeable on laptops, where the wireless module is often active by default for background services. Manually changing this setting allows you to strictly set the priority. Ethernet over wireless connections.

It's important to note that disabling Wi-Fi isn't always the best solution, as many modern apps and system services rely on an active wireless interface to discover devices on the local network. Therefore, it's better to change its priority rather than disable the module.

Preparing equipment and checking connections

Before delving into the deep system settings, you need to make sure the components are physically in good condition. Make sure the cable LAN The network card and router are functioning properly, and the indicators on the network card and router are lit or blinking. The lack of a physical connection will render any software adjustments useless.

Check if the computer can see the connected cable. Just look at the network icon in the system tray: if a monitor icon with a cable appears, the physical layer is working. If only the Wi-Fi star is lit, the problem may be with the drivers or the cable itself.

• 🔌 Insert the Ethernet cable into the port on your laptop or PC until you hear a click.
• 📶 Make sure the Wi-Fi module is enabled and sees available networks.
• 💡 Check the indicator light on the router: the LAN port should be lit.

If the indicators don't light, try a different cable or a different port on the router. Sometimes the problem lies in a physically damaged connector or broken wires inside the cable, which will prevent you from switching to wired mode even with the correct settings.

Method 1: Changing the interface metric (Basic method)

This is the most effective way to force Windows 10 Give priority to the cable. We'll manually assign a lower number (high priority) to the wired adapter and a higher number (low priority) to the wireless adapter.

To begin, open the Run window by pressing the key combination Win + R. Enter the command ncpa.cpl and press Enter. The "Network Connections" window will open, displaying all available adapters.

Find your wired adapter (usually labeled "Ethernet" or "Local Area Connection"). Right-click it and select "Properties." In the list of components, find "Internet Protocol Version 4 (TCP/IPv4)," select it, and click "Properties" again.

In the window that opens, click the "Advanced" button in the lower right corner. Uncheck "Automatically assign metrics." In the "Interface metric" field, enter a number. 10This will set a very high priority for the cable connection.

Now follow the same steps for your Wi-Fi adapter. Find "Wireless Network," go to IPv4 Properties, then "Advanced." Uncheck the Automatic Metrics box and set a value, for example, 50 or 100The higher the number, the lower the priority.

⚠️ Caution: Do not set the metric to 0 or negative numbers. The minimum acceptable value is 1. Using too low a value for Wi-Fi may result in loss of connection to local devices if the cable is disconnected.

After applying the settings, click OK in all open windows. The system will apply the changes immediately; a reboot is usually not required, but it is recommended to reset the DNS cache and routing tables.

Method 2: Disable Automatic Wi-Fi Shutdown

In some cases, Windows 10 doesn't automatically switch because it's configured to save power or has specific roaming rules. There is a setting that allows the system to automatically disable Wi-Fi when a wired connection is available, but it's hidden in the registry or group policies.

However, a safer and simpler option is to use the "Metered Connection" feature. If you designate your Wi-Fi connection as metered, Windows will try to minimize traffic through it, effectively ignoring it for background tasks if there's an alternative.

Go to Settings → Network and Internet → Wi-FiClick "Manage known networks," select your network, and enable "Metered connection." This won't completely switch traffic, but it will reduce wireless activity.

The table above will help you navigate the differences in settings. Please note that the metric values ​​may vary, but the key is that the cable number is lower than the Wi-Fi number.

Diagnostics and routing verification

After making all the changes, you need to verify that the system is actually using the cable. Simply having the "Ethernet" icon in the system tray may not be enough, as the Wi-Fi icon may also remain active.

Open the command prompt. Click Win + R, enter cmd and press Enter. To check the current traffic route, enter the command:

route print

In the list that opens, find the "Interface" line and look at the interface order. The Ethernet interface should be higher in the priority list. You can also ping the external resource by disconnecting the cable for a second: if the ping stops immediately, the traffic was going through the cable.
