Check if the gold connectors of the card are clean, if not, clean the surface of the connector. 2. Make sure the PCI Express card is properly inserted into the PCI Express slot, if not, turn off the computer and plug it in again. 3. If this is still not the case, please change another PCI Express slot on your motherboard. 4. The motherboard itself could be defective. You can try another motherboard to test whether the 2.5Gbps Ethernet PCle Card works or not. Why can't I use Gigabit Ethernet transfer speeds? 1. Please confirm that your Ethernet environment supports Gigabit structure. 2. Please use CAT 6 UTP/STP cable Review: Defective - Worked fine then it failed completely after just over a month, past the return window. Review: No te compliques. I225-V es el chip que buscas para tu tarjeta de 2.5Gb. - Cuando llevas tiempo en esto de las tarjetas de red, te das cuenta que para 2.5Gb (y en especial para 10Gb), si no te quieres complicar y quieres compatibilidad unánime, eliges una tarjeta que use el chi I225-V (y el X550 para 10Gb) y te olvidas. Funcionan y punto. Si te quieres complicar, verás pronto que hay mil y un chipsets de 2.5Gb y no digo que todos sean malos, solo que en mi experiencia, al final es que no merece la pena. Compra esto y usa tu tiempo para otra cosa. ## Features - PCI Express 3.1: 5GT/s support for x1 width (lane) - Network Interfaces:Integrated MAC + BASE-T PHY.
