Upgrade your network infrastructure with this Quad Port Gigabit Ethernet Network Card, designed for applications demanding high-density connectivity. Powered by dual Realtek RTL8111H Gigabit Ethernet controllers, this PCIe x1 adapter adds four independent RJ45 ports to your server, desktop, or custom networking build, providing the flexibility and performance needed for soft routers, virtualization hosts, and multi-device environments.
High-Density Gigabit Connectivity
Each of the four ports supports 10/100/1000Mbps auto-negotiation, allowing seamless integration with existing network infrastructure. The card fully supports both full-duplex and half-duplex operation modes, adapting to the requirements of connected devices and network switches.
Dual-Chip Architecture
Unlike single-chip quad-port designs, this adapter utilizes two independent RTL8111H controllers, each managing two ports. This architecture provides improved thermal distribution, enhanced fault tolerance, and consistent performance across all four connectionsespecially beneficial for high-traffic environments.
PCIe x1 Compatibility
The PCI Express x1 interface ensures broad compatibility with a wide range of motherboards, from consumer desktops to enterprise servers. The card installs easily into any available PCIe slot (x1, x4, x8, or x16), making it an ideal upgrade for systems lacking built-in multi-port networking.
Unique MAC Addresses
Each of the four ports is assigned a unique, pre-programmed MAC address, ensuring proper network identification and eliminating conflicts in managed network environments. This feature is essential for virtualization, software-defined networking (SDN), and enterprise deployments where precise device identification is required.
Versatile Application Support
With broad driver support across Windows and Linux operating systems, this card is compatible with leading soft router platforms including:
- pfSense, OPNsense, OpenWrt, iKuai, RouterOS
- Windows Server environments
- Virtualization hosts (VMware ESXi, Proxmox, Hyper-V)
- Linux-based NAS systems
