Based on the Realtek RTL8126 chipset, the StarTech PR25GR‑NETWORK‑CARD delivers up to 5000 Mbit/s aggregate transfer rate, wired connectivity and compatibility with Windows and Linux. Designed for workstations and servers requiring multi‑gigabit LAN and reliable wired networking.

## Long description

Add two 5 Gbps Ethernet ports to a PCI Express-enabled computer using this TAA-compliant 2-port Multi-Gigabit network card with a Realtek RTL8126 chipset. The adapter provides 2.5G and 5G speeds over existing Cat5e cabling to deliver multi-gig performance without rewiring, and includes both full-height and low-profile brackets for installation in desktop or server systems.
Advantages
This PCIe network card is plug-and-play on major operating systems, with drivers that auto-install on Windows, Windows Server and many Linux distributions. It supports multi-speed auto-negotiation (10/100M/1G/2.5G/5G), 9K jumbo frames to reduce packet overhead, Wake-on-LAN for remote boot, VLAN tagging for traffic segmentation, and link/activity LEDs for visual status and diagnostics. The card is compatible with Intel and AMD platforms with PCIe x1/x2/x4/x8/x16 slots and is delivered with both pre-installed full-height and an included low-profile bracket.

How to use
Power down the computer and install the card into an available PCI Express slot (x1, x2, x4, x8 or x16). Attach the appropriate bracket (full-height or low-profile) before securing the card in the chassis. Boot the system and allow the operating system to auto-install drivers or install drivers provided by the vendor if required. Connect Ethernet cables to the RJ45 ports; the link/activity LEDs indicate connection speed and traffic. Configure network settings, VLANs or Wake-on-LAN options in the operating system or network management tools as needed.
Recommendations
Use Cat5e or better cabling to achieve 2.5G/5G speeds and verify switch or router support for multi-gigabit links. For servers or compact systems, choose the appropriate bracket before installation and keep drivers updated for best compatibility and performance.
