Many users are faced with a situation when connected to a computer Ethernet cable does not become the primary internet source while the wireless module is active. Operating system Windows 10 By default, it tries to automatically determine the best path, but the selection algorithm does not always work correctly, especially if the network card drivers are outdated or the adapter parameters are configured haphazardly.
It often feels like the computer is "ignoring" the cable, continuing to use a slow or unstable connection through Wi-Fi routerThis can lead to slow online gaming, buffering of high-definition video, and dropped video calls. The solution lies in manually prioritizing network interfaces, allowing the system to clearly prioritize a wired connection over a wireless one.
In this article, we'll cover not only simple methods for disabling Wi-Fi, but also more advanced ways to manage interface metrics. You'll learn how to force operating system use a wired connection even if the wireless signal remains on for other devices on the local network.
Physical connection and initial diagnostics
Before delving into software settings Windows 10, you need to make sure that the physical layer of the connection is working properly. Cable type Vitaya Para (twisted pair) must be in good condition, and the connectors RJ-45 The cables are securely latched into the ports on your computer and router. The absence of a distinctive click when inserting the cable often indicates a loose connection, which prevents stable operation.
After connecting the cable, check the network card's LEDs. They typically light orange or green, indicating the presence of a link (Link) and data transfer activity (Activity). If the LEDs are silent, the problem may lie in a faulty cable, a faulty port on the router, or missing drivers for the network card. network card in the device manager.
It is important to understand that Windows The router may see the cable but not receive an IP address if the DHCP server is disabled on the router or static addressing is configured that is incompatible with the current subnet. In this case, the connection status will display as "No Internet Access," and the system will continue to use Wi-Fi by default.
⚠️ Attention: If you are using a corporate network or specific provider equipment, manually changing the IP address or DNS settings without the administrator's approval may result in loss of access to local resources.
Easy Method: Manually Disabling the Wi-Fi Adapter
The most obvious and radical way to force a computer to use a wired connection is to disable the wireless module in software. In this case, Windows 10 there will simply be no choice, and all traffic will go through EthernetThis is a temporary solution, but it is guaranteed to work 100% of the time.
To do this, press the key combination Win + R, enter the command ncpa.cpl and press Enter. The "Network Connections" window will open, displaying all available adapters. Find the icon labeled "Wireless Network" or "Wi-Fi," right-click it, and select "Disable."
After this procedure, the Wi-Fi icon in the tray will change to a red cross, and the system will redirect all traffic through LAN portThe advantage of this method is its simplicity, but it prevents you from using wireless devices such as mice, keyboards, or smartphones if they are connected to the same network.
- 🔌 Reliability: The method eliminates any conflicts of priorities, since the alternative path simply disappears.
- 📉 Power consumption: Disabling the Wi-Fi module may slightly reduce the laptop's power consumption.
- ⚙️ Flexibility: Allows you to quickly switch between operating modes without changing the system registries.
Setting priority via interface metric
A more professional approach is to change interface metricsA metric is a numerical value that Windows Used to determine route priority. The lower the metric number, the higher the priority of the connection. By default, the system attempts to calculate this value automatically, but you can set it manually.
Open the network connections window again using the command ncpa.cplFind your wired connection (usually labeled "Ethernet"), right-click it, and select "Properties." In the list of components, find "Internet Protocol Version 4 (TCP/IPv4)," select it, and click "Properties," then "Advanced" in the window that opens.
At the bottom of the window, you'll see a checkbox labeled "Automatically assign metrics." Uncheck it and enter the value in the "Interface metric" field. 10This is a very low value that guarantees high priority. A similar operation needs to be performed for the Wi-Fi adapter, but assign it a metric, for example, 50 or 100.
| Parameter | Meaning for Ethernet (Wire) | Meaning for Wi-Fi (Wireless) | Impact on the system |
|---|---|---|---|
| Interface metrics | 10 | 100 | Determines the gateway priority |
| Automatic metrics | Disabled | Disabled | Fixes manual selection |
| Default Gateway | Active | Active (but secondary) | Traffic routing |
| Connection type | Local area network | Wireless network | Physical level |
⚠️ Attention: Network driver interfaces may vary depending on the manufacturer (Realtek, Intel, Killer). If you don't see the "Metric" field, check for driver updates on the motherboard manufacturer's official website.
☑️ Checking metric settings
Managing Windows network profiles and priorities
operating system Windows 10 Classifies networks as "Private" or "Public." While this is primarily a security concern, the profile type can affect how the system handles device discovery and sharing. For a wired connection on a home network, the "Private Network" profile is recommended.
To check or edit your profile, go to Settings → Network & Internet → EthernetMake sure the "Private" profile is selected for the active wired connection. This tells the system that this connection can be trusted more than public Wi-Fi hotspots, which indirectly affects the priority of discovery services.
You should also pay attention to the "Mobile hotspot" or "Internet sharing" feature. If it's enabled, Windows may attempt to balance traffic between adapters to share the internet with other devices, which can sometimes cause conflicts. Make sure that in the section Network and Internet → Mobile hot-The spot function is disabled unless you specifically use it.
Why does Windows ignore metric settings?
Sometimes third-party antivirus programs or VPN clients have their own network drivers (TAP adapters) that can intercept traffic control and ignore standard Windows metric settings. In such cases, temporarily disabling the VPN or firewall for testing can help.
Using the Command Prompt to Reset the Network
If manual settings are not applicable or the system is unstable, an effective method is to completely reset the network settings via the command prompt with administrator privileges. This allows you to clear the DNS cache, reset the routing table, and update the Winsock configuration.
Launch the command prompt (cmd) as administrator. Enter the command netsh int ip reset and press Enter. This command will reset the registry keys responsible for TCP/IP settings to their default values, which often resolves software glitches that prevent proper switching.
Next, run the command ipconfig /flushdns to clear the DNS cache and netsh winsock reset to reset the Winsock directory. After completing all the commands, be sure to restart your computer. When booting Windows 10 will re-scan the network adapters and apply the correct priorities.
netsh int ip resetipconfig /flushdns
netsh winsock reset
Diagnosing shifting problems
In situations where none of the methods help, a thorough diagnosis is required. The problem may lie in an IP address conflict, where both Wi-Fi and Ethernet have received the same addresses on the local network, or in a driver malfunction. Realtek PCIe GBE Family Controller.
Use the built-in troubleshooting wizard. Right-click the network icon in the system tray and select "Troubleshoot." The system will attempt to automatically find and fix errors related to the default gateway or access to DNS servers.
Also check the device manager (devmgmt.msc). Make sure there are no devices with a yellow exclamation mark in the "Network Adapters" section. If one is present, try uninstalling the device and clicking "Scan for hardware changes" to have Windows reinstall the driver.
- 🔍 Logging: Check the Windows Event Viewer under Windows Logs → System for NetworkProfile or DHCP-Client errors.
- 🔄 Router: Rebooting the router often resolves issues with issuing a default gateway to wired clients.
- 💻 Drivers: Download drivers only from the official websites of motherboard or laptop manufacturers.
⚠️ Attention: Settings interfaces and menu item names may vary slightly depending on the Windows 10 build version (e.g., 21H2, 22H2) and interface language. Always consult the latest Microsoft documentation if menu items have been renamed.
Frequently Asked Questions (FAQ)
Why doesn't Windows 10 automatically switch to cable?
This most often occurs due to identical interface metrics or driver errors. The system "thinks" both connections are equal and continues to use the one established first (usually Wi-Fi). Manually adjusting the metric solves the problem.
Do I need to unplug the Wi-Fi antenna if I have a cable connected?
No, you don't need to physically unplug anything. Simply disable the adapter or adjust its priorities in software. However, if you don't use Wi-Fi at all, disabling it may slightly increase security and reduce radio interference.
Does cable type (Cat5, Cat6) affect switching speed?
The cable type affects the maximum connection speed (100 Mbps vs. 1 Gbps and above), but not the actual priority switching. However, a damaged cable can cause constant disconnects, causing the system to drop the connection and attempt to switch to Wi-Fi.
Can antivirus software block LAN switching?
Yes, some "Network Protection" or "Traffic Control" features in third-party antivirus programs (Kaspersky, ESET, Avast) may block network profile or priority changes. Try temporarily disabling your antivirus to check.
