This M.2 to 5G wired ethernet card adopts professional Realtek RTL8126 main control chip, providing up to 5000Mbps ultra-high network speed, far exceeding the transmission limit of traditional 1Gbps onboard network ports. Equipped with one independent shielded copper RJ45 port, it supports auto-negotiation of 5G/2.5G/1G/100M/10M multiple rate modes, fully matching Cat6a and above network cables for lossless high-speed transmission.
Optimized for gaming scenarios, the RTL8126 chip integrates low-latency packet processing technology, effectively reducing ping jitter and sudden lag spikes during competitive gaming, live streaming and simultaneous large file downloading. It supports hardware CRC, TCP/IP offloading and VLAN QoS priority scheduling, lowering CPU occupancy and avoiding frame drops caused by network resource occupation.
Designed with universal M.2 B+M Key slot, it can be directly inserted into the motherboards spare M.2 slot without occupying valuable PCIe X16 slots reserved for graphics cards. The built-in multi-layer EMI shielding circuit suppresses electromagnetic interference inside the chassis, maintaining continuous stable connection under long-hour full-load operation for gaming hosts, NAS storage servers and mini workstations.
It supports jumbo frames up to 16K bytes, remote wake-up and energy-saving Ethernet standards, balancing transmission efficiency and power consumption. Official complete drivers cover all mainstream Windows versions and mainstream Linux distributions, supporting plug-and-play recognition after simple installation without complex BIOS configuration.
Perfect for gamers upgrading network speed, media servers storing 4K video resources, and industrial mini PCs requiring high-bandwidth wired communication. It is a compact, space-saving high-performance network upgrade solution for modern M.2-equipped motherboards.
