Upgrade to 2.5gig Ethernet PCIe Slot
This upgrade to 2.5gig Ethernet is easy to install into a PCIe slot and drivers are included on the supplied mini CD. Many drivers are included including Windows 11, 10, Mac and Linux. Full speed is achieved using Cat 6 wire. Both full form and small form factor hardware included - easy to change out. Ethernet socket has two LED indicators for link and speed which is good since other cards may not have these indicators or have holes to see through to an LED on the inside surface of the card. The Realtek chip and the software may be able to go to 10gig in the future since there is some references in drivers and other information of the system. Maybe a firmware update in the future for this? Overall, this is a great product and very reasonable in price and support.

Perfect card.
I bought this to test 2.5GbE on a PC that did not support it. This thing is plug-and-play, and worked everywhere I connected it. I bought it in 2021, and it's still working just as well as the day I got it!

De excelente tamaño
Acabo de instalar la tarjeta de red, si costo trabajo para que mi tarjeta madre la reconociera, aunque al ser pci, y puedes conectarla en los puertos pci-e 16x, posiblemente mi tarjeta no la reconoce de este modo, y fue necesario colocarla en los pci. con eso la detecto windows sin problemas, ya solo busque el driver directo del fabricante del chipset, el cual es Realtek, y permitió que funcionara un poco mejor. A comparación de mis anteriores test con el conector de red de la tarjeta madre, si varia la velocidad de internet, pero puede que con el tiempo se ajuste y me de mejores resultados. la primera foto es del antes, y la segunda con la tarjeta

Good for upgrading from 1Gb to 2.5Gb network.
Used to upgrade an older PC for use on a 2.5Gb network. Hardware installation was easy and took 10 minutes, and Windows 10 installed a driver for it so it worked straight away. However I was getting 280-odd MB/s incoming, but only 170-ish outgoing. So I installed the driver on the included CD (Realtek 8125 chipset) and that got full speed in both directions. So far seems like a great, economic way to upgrade.

La Mejor Relación Calidad-Precio
Aparte de muy buen precio para un 2.5 gigabit, mis pings bajaron de 25ms a 8ms.
