Wi-Fi vs Ethernet speed on Windows: what to expect

Compare Wi-Fi and Ethernet for speed and stability, and learn how to see which one your PC is using and how busy it is.

Both Wi-Fi and Ethernet can deliver fast internet, but they behave differently. Ethernet is a direct cable, so it is steadier and less affected by walls, distance and neighbors. Wi-Fi is convenient, but its speed depends on signal quality and interference.

Where each one shines

• Ethernet: consistent speeds and the best choice for desktops, game consoles and large transfers. A modern cable and port can carry a gigabit connection.
• Wi-Fi: flexible and good enough for most browsing and streaming. Speed drops with distance and obstacles, and the 5 GHz band is usually faster than 2.4 GHz at shorter range.

Check which one you are using

When both are connected, Windows normally prefers one of them. Open Settings → Network & internet to see it, or follow how to check which network adapter is active.

Compare them with a live readout

1. Place the PC where it normally sits.
2. Start a large download on Wi-Fi and watch the download speed on the taskbar.
3. Plug in the cable, disable Wi-Fi and repeat the same download.

If Ethernet is much steadier, the problem is likely your wireless link rather than your plan. Use Select Network Connections in NetSpeedDisplay to pick the adapter you want to watch.

A caution

Two different downloads from two different servers are not a fair comparison. Use the same large file, and run it more than once. A traffic monitor shows what actually moved, not what your connection could do, so also run a speed test when you need a ceiling. A traffic monitor is not a speed test.
