PCIe to Dual Gigabit Ethernet Controller Card

PCIe to Dual Gigabit Ethernet Controller Card


  • 2-port Gigabit Network Card: Wide Range of Applications, such as Servers, Network Attached Storage (NAS), Soft Router and Firewall, etc.
  • Full Speed Operation: Based on RTL8111H Chip, the upstream bandwidth is PCIe 1.0 X1=2.5Gbps, so two ports can operate simultaneously at 1000Mbps full speed. (Note: Only one PCIE X1 slot is required for installation, no wasted PCIE X16 slot).
  • Plug & Play in Windows: If your PC does not recognize the network card or the speed can not reach 1000Mbps level, please reinstall the driver. https://drive.google.com/drive/folders/15UkeFpoDpkyQyv3zD8Z3MxaYZ_Es2Jxj?usp=sharing.
  • Other OS Compatibility: MAC OS/Linux/Centos/RHEL/Ubuntu/Debian/DSM/OpenWrt/PFSense/OPNSerse/IKUAI, etc. (Note: You may need to install the driver if your OS can not find the network card).
  • Virtual Machine Software: VMWare ESXi 5. x and 6.x/Proxmox/unRaid. (Note: you need to install the driver for VMware ESXi 7.0 or above)
