If your desktop is stuck with a failing or 100Mbps onboard LAN port, this compact PERCKO card offers a simple, reliable fix. Built around the proven Realtek RTL8111 controller, it adds a standard gigabit RJ45 connection for everyday home or office use. The PCIe X1 interface fits any X1, X4, X8, or X16 slot, and its small footprint won’t block nearby components like your graphics card. Both full-height and low-profile brackets are included, making it compatible with everything from large towers to slim small-form-factor cases.
The RTL8111 chipset is widely supported and handles 10/100/1000Mbps auto-negotiation with ease. As long as your router, switch, and cabling are gigabit-capable, it will establish a stable 1000Mbps link. Features like WOL, VLAN tagging, and jumbo frames are available on supported revisions, while LED indicators provide quick status checks. Most modern Windows and Linux systems recognize it automatically for a true plug-and-play experience, though a driver may be needed for older operating systems.
This is a single-port gigabit NIC meant for upgrading an aging PC or replacing a dead onboard port—ideal for streaming, file transfers, and daily work. It is not a 2.5G or 10G card and isn’t intended for professional soft-router or multi-port setups. For what it is, the PERCKO RTL8111 delivers exactly what a practical wired upgrade should: no fuss, broad compatibility, and dependable gigabit connectivity.
