M.2 A+E Key Gigabit Ethernet Adapter Card with Intel I210AT Chip, Single RJ45 Copper Port Wired LAN NIC for Mini Desktops and Low-Power Servers

This M.2 A+E Key gigabit wired network card adopts mature Intel I210AT dedicated network chip, providing reliable high-speed wired network expansion for mini ITX desktops, soft routers and small file servers.

Different from traditional PCIe network adapters, it uses the motherboards spare M.2 A+E wireless slot for installation, which saves limited PCIe slots for graphics cards, SSD expansion cards and other hardware devices.

The single RJ45 copper network port automatically matches 10Mbps, 100Mbps and 1000Mbps bandwidth, fully compatible with mainstream household and industrial Cat5e and Cat6 wiring environments. The I210AT chip integrates complete hardware offloading technology, which greatly reduces the hosts CPU computing pressure during large file transmission, multi-user access and video streaming.

Multi-layer metal shielding is added to the PCB to isolate signal interference from CPU, GPU and power supply inside the chassis, effectively preventing network packet loss, sudden disconnection and signal jitter under high-load working conditions. It supports practical functions including remote wake-on-LAN, IEEE 802.1Q VLAN division, 802.1P traffic priority and jumbo frame transmission, perfectly fitting unattended server operation scenarios.

Complete driver packages are provided for Windows and all mainstream Linux systems, ready to use after simple driver installation. The slim card body is easy to install and fix, ideal for mini PC assembly, office desktop network upgrades and low-power server networking transformation.
