QNAP Single-Port 2.5GbE PCIe Network Expansion Card

The QNAP QXG-2G1T-I225 is a network expansion card that gives any compatible computer or QNAP NAS a single 2.5 GbE RJ45 port. By installing it in a free PCIe Gen2 x1 slot, you can raise network throughput well above traditional gigabit speeds without replacing existing cabling.

The card relies on the Intel Ethernet Controller I225-LM, a widely supported chipset that works smoothly with Windows, Linux, and QNAP’s QTS or QuTS hero operating systems. Support for PXE boot, Wake-On-LAN, jumbo frames, and VLAN tagging lets you fold the card into a broad range of home-lab or business networks. QNAP includes a full-height bracket, a low-profile bracket, and a dedicated bracket for select QNAP NAS models, so the card can slot neatly into tower PCs, compact workstations, or rackmount enclosures.

Typical users include media professionals who move large video files between a workstation and a NAS, small offices that want faster shared folder access without rewiring, and home enthusiasts who run virtual machines or game servers. Backward compatibility with 1 GbE and older standards means the upgrade can happen in stages, with the card automatically negotiating the highest speed your switch supports.
