This article covers Microsoft Surface Ethernetアダプター3.0。.

Overview

The Microsoft Surface Ethernet Adapter 3.0 is a dedicated wired LAN adapter designed specifically for Surface devices. It connects via USB 3.0 and delivers up to 1 Gbps data transfer speeds, providing a stable network connection even in environments where Wi-Fi is unreliable. Compact and lightweight, the adapter features a simple black design that blends well with Surface devices. Simply plug it into a USB 3.0 port and it is recognized automatically without any driver installation, making setup effortless.

Connectivity & Compatibility

The adapter uses a USB 3.0 interface (backward compatible with USB 2.0) and supports 10/100/1000BASE-T Gigabit Ethernet. It works with most Surface models that have a USB-A port, including the Surface Pro, Surface Laptop, and Surface Book series. Note that newer Surface models with only USB-C ports (such as the Surface Pro X) will require a separate USB-C to USB-A adapter for compatibility.

Product Info

As a Microsoft-branded accessory, this adapter offers high reliability and guaranteed compatibility with Surface devices. It sits in the mid-range market tier — more expensive than third-party alternatives, but the peace of mind from official compatibility testing justifies the premium for many users. The warranty period is typically one year (varies by region). The package includes only the adapter itself; no driver disc or additional cables are included.

Best Use Cases

Surface users who need wired networking: Ideal for conference rooms, hotels, or home offices where Wi-Fi signals are weak or unreliable. Users who transfer large files frequently: Gigabit speeds provide faster and more stable data transfers than most wireless connections. * Security-conscious corporate users: Avoid public Wi-Fi risks by using a wired connection for sensitive work. This adapter is less suitable for users with USB-C-only Surface models or those who prioritize minimal cable clutter.

Things to Consider

This adapter uses a USB-A connector, so it cannot be used directly with USB-C-only Surface models. When connected to a USB 2.0 port, speed is limited to 100 Mbps. While third-party alternatives are cheaper, the official Microsoft adapter offers guaranteed compatibility and build quality that may be worth the extra cost for Surface owners. ## FAQ
