2.5 Gigabit Ethernet Network Card: With the 2.5G Base-T Technology, GLOTRENDS LE8245F 2.5Gbps network card can reach 2.5x faster than typical Gigabit adapters. Backward compatible with 1000/100Mbps.
2 x 2.5 Gigabit + 2 x 100/1000 Megabit RJ45 port: PCIE 2.0 X2 (10Gbps ) upstream and 6.4Gbps downstream bandwidth. So 4 LAN ports share 6.4Gbps, only 2 ports can operate at full 2.5Gbps simultaneously, and the other two ports operate at 100/1000Mbps.
Play and Plug, there is no need extra driver. But if your PC does not recognize the network card or the speed does not reach the 2.5Gb level, please reinstall the driver. (Note: Please make sure that both connected ports support 2.5Gb and that the connected cable is at least CAT5E)
