Does Surface Pro 5 have an Ethernet port?

No, the Surface Pro 5 lacks a native Ethernet port; use a USB-A or USB-C Ethernet adapter, hub or dock to connect via RJ-45.

An Ethernet port (RJ-45 jack) is a wired network interface that offers a stable connection with higher bandwidth and lower latency compared to Wi-Fi. It is perfect for large file transfers, video conferencing and online gaming.

All Surface Pro 5 models lack a built-in Ethernet port. To connect via a wired network, plug a USB-A or USB-C adapter, hub or docking station with an RJ-45 jack into your device. The USB-C 3.0 port supports up to 5 Gbps, so Gigabit Ethernet adapters will run at full speed.
