2.5G Gigabit Ethernet Network Card M.2 A+E Key with 18cm Cable

This is a high-speed network expansion card designed for computers that lack built-in gigabit or faster Ethernet connectivity. It uses the M.2 form factor with A+E keying, making it compatible with a wide range of laptops and mini PCs that support this interface. The card features a Realtek RTL8125BG controller, which enables data transfer speeds up to 2.5Gbps, significantly improving internet and local network performance. It includes an 18cm Ethernet cable for easy connection to a router or modem.

The card supports multiple networking protocols such as PXE, DPDK, WOL, iSCSI, and Jumbo Frames, making it suitable for both home and professional environments. It is compatible with various operating systems including Windows, Linux distributions, and VMware ESXi. However, it does not support FCoE or hot swapping, so users must ensure the device is powered off before installation or removal.

The card comes with a full-height and low-profile bracket, allowing it to fit into different types of computer cases. Its compact design makes it ideal for small form factor systems where space is limited. The RJ-45 port provides a standard Ethernet connection, and the included bracket ensures secure installation in most M.2 slots.

Installation requires a compatible M.2 slot and a basic understanding of hardware setup. Users should follow the manufacturer's guidelines to avoid damage during installation. This card is particularly useful for users looking to upgrade their network speed without replacing their entire system.
