Switching from a wireless to a wired connection is often the only viable solution for those experiencing signal instability, slow speeds, or mission-critical tasks like online gaming and 4K streaming. Wired connection (Ethernet) provides significantly higher data transfer stability and minimal latency (ping), which is especially important in conditions of busy frequency ranges, when the airwaves are overloaded with signals from neighboring routers.
Many users mistakenly believe that simply plugging in a cable is enough, but modern operating systems and devices have their own network prioritization features that require manual intervention for proper operation. Windows, macOS, game consoles and Smart TV may react differently to the simultaneous presence of both types of connections, sometimes ignoring the cable in favor of a weak Wi-Fi signal.
In this article, we will take a detailed look at the physical connection, software priority settings in various operating systems, and also consider typical errors that users encounter when switching to wired interfaceYou'll learn not only how to connect devices, but also how to diagnose problems, ensuring maximum internet speed.
⚠️ Note: Network adapter settings interfaces may vary depending on the operating system version and driver model. Always verify the menu item names with the official documentation from your device manufacturer, as software updates often change the layout of functions.
Advantages of a wired connection over a wireless one
The main reason why users seek change connection The difference between Wi-Fi and cable lies in the fundamental differences in the physics of data transmission. Wireless signals are subject to attenuation, reflection from walls, and interference with household appliances such as microwaves and baby monitors. Cables avoid these problems, transmitting the electrical signal directly from the router to the receiver without any loss in the air.
In addition, the wired connection provides full duplex communication, allowing you to simultaneously send and receive data at the maximum speed advertised by your provider. While Wi-Fi divides the bandwidth between all connected devices and must switch between receiving and transmitting, an Ethernet cable (especially CAT5e and above) guarantees a stable connection for every device.
- 🚀 Maximum speed: Cable allows you to realize the full potential of your plan, which is often limited by interference on wireless connections.
- 🛡️ Data security: Physical access to a cable is more difficult for an attacker to obtain than intercepting a radio signal, making LAN preferable for financial transactions.
- 📉 Minimal ping: Response time in games and video conferences via cable is minimal and stable, without sudden jumps (jitter).
Connection reliability is also worth mentioning. If you use the internet for mission-critical tasks, such as remote work or video surveillance, the risk of sudden Wi-Fi connection loss is virtually eliminated with a high-quality cable. Stability In this context, it is even more important than peak speed, as it ensures the continuity of business processes.
Necessary equipment and cable preparation
To set up a wired connection, you'll need a basic set of equipment. First and foremost, this is the router or modem itself, which must have a free port. LAN (they are usually yellow and numbered). The second required element is the network cable, known as Vitaya Para (twisted pair), which must be in good working order and comply with data transmission standards.
Cable length plays an important role: standard Ethernet Allows data transmission without loss of quality over distances of up to 100 meters. However, for home use, it's important not to overdo the length, as an excessively long cable installed near powerful electrical appliances could theoretically pick up interference, although this is rare with modern shielded cables.
Pay attention to the cable category, which is indicated on its jacket. For home use and speeds up to 1 Gbps, a category of CAT5eIf your plan provides speeds above 1 Gbps or you are planning to expand your network, it makes sense to purchase a category cable CAT6 or CAT6a, which has improved protection against crosstalk.
Physically connecting the device to the router
The physical connection process is extremely simple and doesn't require any special tools, but it does require some attention. You need to find the port. LAN on the back of the router. Don't confuse it with the port WAN or Internet, which is usually highlighted in blue and is used to connect the cable from the provider.
Insert one end of the cable into an available LAN port on your router until the locking mechanism clicks into place. Connect the other end to the network port on your computer, laptop, TV, or gaming console. RJ-45 It is designed so that it cannot be inserted incorrectly unless excessive force is applied.
☑️ Checking the physical connection
Once connected, pay attention to the LED indicators next to the network port. Typically, one indicator will be solid (indicating a link), while the other will blink, indicating data transfer. If the indicators do not light up after connecting a working cable, this most often indicates a problem with the network card drivers or a physical fault in the port.
⚠️ Caution: Never force the cable into or out of the port. The plastic tab is very fragile; if it breaks, the connection will be unstable, and the cable will need to be replaced or the connector repaired.
Setting Network Priority in Windows
operating system Windows By default, it prioritizes a wired connection if both interfaces are active. However, in some cases, especially when using third-party connection managers or specific corporate network settings, the priority may shift. Checking and adjusting the interface metric is a key step to ensure proper operation over a wired connection.
To configure manually, open the Control Panel menu and go to the section Network and Internet -> Network and Sharing CenterClick the "Change adapter settings" link. In the window that opens, find your local area connection (Ethernet), right-click it, and select "Properties."
In the list of components, select "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties," then "Advanced." This is where you'll find the "Interface Metric" setting. To force Windows to use the cable, uncheck "Automatically calculate metric" and enter the value 10For the Wi-Fi adapter, you can set the value 20 or higher.
netsh interface ipv4 show interfacesThis command, entered in the command prompt with administrator privileges, will allow you to view the current metrics of all interfaces. If the wired connection metric is higher (the number is higher) than the wireless one, the system will attempt to use Wi-Fi. The smaller the metric number, the higher the connection priority for the operating system.
What if the metric settings are not applied?
Sometimes antivirus software or VPN clients can hijack control of network interfaces. Try temporarily disabling third-party network software and restarting your computer for the changes to take effect.
Switching to a cable on macOS and Linux
In the ecosystem Apple Network service management is implemented through service ordering. macOS will automatically switch to Ethernet when a cable is connected, but you can manually adjust the priority order to eliminate any doubt. To do this, go to System Preferences -> Network.
Click the button with three dots or the gear (depending on your macOS version) and select "Set Service Order" (Set Service Order). In the window that opens, drag Ethernet or USB LAN (if using an adapter) to the very top of the list. Click "OK" and then "Apply" to save the changes.
In operating systems based on Linux, such as Ubuntu or Debian, are often managed through the NetworkManager graphical interface or through configuration files. In the graphical interface, it's usually sufficient to disable Wi-Fi once a wired connection is established, as Linux by default strictly adheres to the "wired is better than wireless" principle.
- 💻 macOS: Uses the concept of Service Order to determine priority.
- 🐧 Linux: Often requires disabling Wi-Fi manually or configuring routing rules via
ip route. - ⚙️ Universality: On all operating systems, if the cable is successfully connected, the Wi-Fi icon in the tray may remain active, but the traffic will go through the LAN.
For advanced Linux users, it is useful to know the command ip route, which will show the current default gateway. If after connecting the cable, the gateway has not changed to the address of your router via the Ethernet interface (for example, eth0 or enp3s0), you may need to restart the network service with the command sudo systemctl restart NetworkManager.
Setting up Smart TV and game consoles
Modern Smart TV TVs (Samsung, LG, Sony) and game consoles (PlayStation, Xbox) often default to Wi-Fi, even if a cable is connected. This is because many TVs don't have an automatic switching feature, and some models require manual activation of the wired interface in the menu.
Go to your device's network settings. The path usually looks like this: Settings -> General -> NetIf the cable is connected but the TV still shows a Wi-Fi connection, find the "Connection Type" option and switch it from "Wireless" to "Wired." Then run the connection diagnostics.
It's important to note that some older TV models or budget smart set-top boxes have network ports limited to 100 Mbps. If your plan exceeds this speed, you won't see any performance gains over cable if the device's port is physically limited. In such cases, hardware limitation The TV will not allow speeds above 100 Mbps
