What Ethernet and Wi-Fi Really Mean

Ethernet is a wired networking technology. It uses a physical cable, usually an RJ45 cable, to connect a device to a router, switch, or modem. Wi-Fi is a wireless networking technology that uses radio signals to connect devices to a wireless access point, often built into the same router.

When people ask, “How to Change Ethernet to Wifi?”, they usually mean one of three things. First, they may want to stop using a cable and connect wirelessly instead. Second, they may want to make Wi-Fi the primary connection while keeping Ethernet available as a backup. Third, they may be moving a device to a new location where running a cable is inconvenient.

Both connection types can provide internet access. Ethernet is often more stable and can offer lower latency. Wi-Fi is more flexible and convenient. The right choice depends on your location, hardware, network load, and security needs.

Why You Might Switch from Ethernet to Wi-Fi

There are many practical reasons to switch. You may be rearranging a room and no longer want a cable across the floor. You may be using a laptop that you carry between rooms. You may be setting up a smart TV, printer, or console in a place where Ethernet is not available. You may also want to reduce cable clutter or make your workspace easier to clean.

Another common reason is mobility. Ethernet ties your device to one physical spot. Wi-Fi lets you move around while staying connected. For video calls, streaming, and everyday browsing, a strong Wi-Fi signal can be more than enough.

However, switching is not always about replacing Ethernet completely. Some users keep Ethernet for demanding tasks and use Wi-Fi for convenience. Others disable Ethernet entirely to avoid confusion when both connections are active.

Before You Start the Switch

Before changing your connection, prepare a few things. This reduces the chance of losing internet access during the switch.

Check That Your Device Has Wi-Fi

Most laptops have built-in Wi-Fi. Desktop computers may not. If your desktop does not have a wireless adapter, you can add one through a USB Wi-Fi adapter or a PCIe Wi-Fi card. Make sure the adapter supports your router’s Wi-Fi standard, such as Wi-Fi 5, Wi-Fi 6, or Wi-Fi 6E.

Find Your Network Name and Password

You will need the Wi-Fi network name, also called the SSID, and the password. These are often printed on a label on the router. If the password has been changed, ask the network owner or check the router administration page.

Confirm Internet Works on Ethernet

Before switching, open a browser and load a few websites while connected by cable. This confirms that your internet service is working. If Ethernet is already failing, fixing Wi-Fi first may be harder because you will not know whether the issue is the network or the wireless setup.

Update Network Drivers

Outdated Wi-Fi drivers can cause slow speeds, dropped connections, or failure to connect. On Windows, use Device Manager or the manufacturer’s support website. On macOS, updates usually come through System Settings. On Linux, use your distribution’s package manager or driver tools.

How to Change Ethernet to Wifi on Windows

Windows makes it easy to switch between wired and wireless connections. The exact menus differ slightly between Windows 10 and Windows 11, but the overall process is the same.

Windows 11 Steps

  1. Click the network icon in the taskbar or open Settings.
  2. Go to Network & Internet.
  3. Select Wi-Fi.
  4. Turn on Wi-Fi if it is off.

netsh wlan show networks
netsh wlan connect name="YourNetworkName"

If you need to view interfaces, you can also use:

ipconfig /all
netsh interface show interface

Be careful with command-line changes. Always verify the network name before connecting.

How to Change Ethernet to Wifi on macOS

macOS handles network switching cleanly. It often prioritizes connections automatically, but you can control the order manually.

macOS Steps

  1. Click the Apple menu and open System Settings.
  2. Select Wi-Fi.
  3. Turn Wi-Fi on.
  4. Choose your network from the list.
  5. Enter the password.
  6. Click Join.
  7. Open Safari or another browser and test the connection.
  8. Unplug the Ethernet cable if you want to remove the wired connection.

Set Network Service Order on macOS

If both Ethernet and Wi-Fi are connected, macOS may use one based on service order. To prioritize Wi-Fi:

  1. Open System Settings.
  2. Go to Network.
  3. Click the three dots or More options menu.
  4. Select Set Service Order.
  5. Drag Wi-Fi above Ethernet.
  6. Click OK or Apply.

This is helpful when you want Wi-Fi to be preferred without fully disabling Ethernet.

How to Change Ethernet to Wifi on Linux

Linux network management depends on the desktop environment and distribution. Many modern systems use NetworkManager, which provides both graphical and command-line tools.

Using the Desktop Interface

  1. Open the system menu or network icon.
  2. Turn on Wi-Fi.
  3. Select your wireless network.
  4. Enter the password.
  5. Connect and test the internet.
  6. Disconnect or disable Ethernet if desired.

Using nmcli on Linux

NetworkManager’s command-line tool, nmcli, is powerful and widely available.

nmcli device status
nmcli radio wifi on
nmcli device wifi list
nmcli device wifi connect "YourNetworkName" password "YourPassword"

To check the active connection:

nmcli connection show --active

To disconnect Ethernet:

nmcli device disconnect eth0

Replace eth0 with your actual Ethernet interface name. You can find it with nmcli device status or ip link.

Check Interfaces with iproute2

ip addr show
ip route show

These commands help you confirm which interface has an IP address and which route is being used.

Router and Network Settings to Check

Sometimes the device is ready, but the router is not. If Wi-Fi does not appear or the connection fails, check the router.

Make Sure Wi-Fi Is Enabled

Log in to your router’s administration page. This is often at an address such as 192.168.1.1 or 192.168.0.1. Look for wireless settings and confirm that Wi-Fi is enabled.

Verify SSID and Password

Check that you are selecting the correct network. Many routers broadcast multiple networks, such as 2.4 GHz and 5 GHz bands. The password is case-sensitive, so enter it carefully.

Confirm DHCP Is Working

DHCP automatically assigns IP addresses. If DHCP is disabled, your device may not receive an IP address on Wi-Fi. For most home networks, DHCP should remain enabled.

Choose the Right Band

2.4 GHz travels farther and penetrates walls better, but it is often slower and more congested. 5 GHz is usually faster but has shorter range. 6 GHz, where available, can be even faster but requires compatible hardware. Choose the band that best fits your location and needs.

How to Set Connection Priority

If you want to know “How to Change Ethernet to Wifi?” in a way that sticks, setting connection priority is important. Without it, your device may keep using Ethernet even after you connect to Wi-Fi.

On Windows, you can adjust interface metrics. A lower metric means higher priority.

Get-NetIPInterface
Set-NetIPInterface -InterfaceAlias "Wi-Fi" -InterfaceMetric 10
Set-NetIPInterface -InterfaceAlias "Ethernet" -InterfaceMetric 50

On macOS, use the service order method described earlier. On Linux, NetworkManager connection profiles can have autoconnect priorities. You can set priority with:

nmcli connection modify "YourNetworkName" connection.autoconnect-priority 10

Higher numbers usually mean higher priority, depending on your setup. Check your distribution’s documentation if unsure.

For a simple home setup, the easiest method is to unplug Ethernet after Wi-Fi is connected and tested. This avoids any ambiguity.

Ethernet vs Wi-Fi Comparison

The table below compares common factors. Actual performance depends on your hardware, router, distance, interference, and internet plan.

Factor Ethernet Wi-Fi
Speed Often faster and more consistent Can be fast, but varies by signal and congestion
Latency Usually lower Usually higher, especially on busy networks
Stability Very stable Depends on distance, walls, and interference
Mobility Limited by cable length High mobility within range
Setup Simple physical plug-in Requires password and signal quality
Security Physical access required Depends on encryption and password strength

If you need the lowest latency for gaming or large file transfers, Ethernet may still be better. If you need convenience and mobility, Wi-Fi is usually the better choice.

Troubleshooting Common Problems

Even simple switches can run into issues. Here are common problems and practical fixes.

No Wi-Fi Option Appears

This may mean the adapter is disabled, missing, or not recognized. Check Device Manager on Windows, System Settings on macOS, or nmcli device status on Linux. Reinstall or update drivers if needed.

Cannot Connect to the Network

Double-check the password. Try forgetting the network and reconnecting. Restart the router and device. Make sure you are not too far from the router.

Connected but No Internet

Your device may be connected to Wi-Fi but not receiving internet. Check whether other devices work. Restart the router. Release and renew the IP address. On Windows, you can run:

ipconfig /release
ipconfig /renew
ipconfig /flushdns

On Linux, you can restart NetworkManager:

sudo systemctl restart NetworkManager

Slow Wi-Fi Speeds

Move closer to the router. Reduce interference from microwaves, cordless phones, and thick walls. Use the 5 GHz or 6 GHz band if available. Check whether many devices are using the network at the same time.

Device Keeps Switching Back to Ethernet

This happens when Ethernet remains connected and has higher priority. Disable Ethernet, adjust interface metrics, or set service order. If you no longer need Ethernet, unplug the cable.

Problems on Public Wi-Fi

Public networks may require a login page. Open a browser and wait for a captive portal. Some networks block certain ports or services. Use a VPN for sensitive tasks, but remember that some public networks block VPN traffic.

Security and Best Practices

When switching to Wi-Fi, security matters. A wireless network can be intercepted if it is not properly protected.

  • Use WPA3 if your router and devices support it. Otherwise, use WPA2.
  • Avoid WEP or open networks for private use.
  • Use a strong, unique Wi-Fi password.
  • Change the default router admin password.
  • Keep router firmware updated.
  • Disable WPS if it is not needed.
  • Use a guest network for visitors and smart devices.
  • Consider a VPN when using public Wi-Fi.

Also, do not share your main Wi-Fi password widely. If you need to give access to guests, use a guest network with its own password. This helps protect your primary devices and files.
