Frequently Asked Questions

Q: What is the M.2 A+E Key Gigabit Ethernet LAN Card used for?

A: This M.2 A+E Key Ethernet LAN card is designed to add a wired Gigabit Ethernet (RJ45) port to any device with an M.2 A+E (NGFF) slot. It's ideal for mini PCs, industrial control boards, or desktops that lack a built-in Ethernet port, providing stable 10/100/1000Mbps wired networking.

Q: Is this M.2 Ethernet card compatible with my operating system?

A: Yes — the RTL8111H-based M.2 LAN card supports a wide range of operating systems including Windows XP through Windows 10 (32/64-bit), Windows Server 2003–2016, multiple Linux distributions, DOS, and macOS 10.4.x and above. Driver installation may be required for some older OS versions.

Q: Does this card fit all M.2 slots?

A: No — this card specifically requires an M.2 A+E KEY slot (the type commonly used for Wi-Fi cards). It will NOT fit M.2 M-Key or B-Key slots used for NVMe or SATA SSDs. Please verify your motherboard has an available M.2 A+E slot before purchasing.

Q: What cable do I need to use with this M.2 Gigabit LAN adapter?

A: This adapter works with standard CAT-5 (or higher) UTP Ethernet cables connected via the single RJ45 port. For optimal gigabit speeds, a CAT-5e or CAT-6 cable is recommended.
