Move more traffic through existing copper infrastructure with a 1-port PCIe network adapter designed for multi-gig deployments. The StarTech PR15GR-NETWORK-CARD adds a single Ethernet port with support for 5G, 2.5G, 1G, 100M, and 10M speeds, giving desktops and servers a faster path to storage, virtualization, and high-volume file movement. Built around the Realtek RTL8126 controller, this adapter is a practical upgrade for teams that need more throughput without a full network refresh. It supports auto-negotiation, 9K jumbo frames, VLAN tagging, and Wake-on-LAN, helping IT align performance with operational requirements. Compatibility across Windows, Windows Server, and Linux simplifies deployment in mixed environments, while PCI Express x1 through x16 slot support broadens hardware fit. For organizations that value measured upgrades over disruptive change, this card delivers a clear step up from standard gigabit networking. It is especially useful where Cat5e cabling is already in place and higher bandwidth is needed now.
