The ethernet port on my motherboard died. No problem, I have an old spare network card. Uh oh, the motherboard only has PCIe slots. So I ordered this and it was delivered shortly after. Installed it, started the computer, and off we go. I didn't have to install a driver, thanks Windows 11.

I highly recommend this adapter! Easy to set up. Works with Windows, Mac, and Linux. And works with Synology DS920+ (which is also built on Linux). Installed on my DS920+ I get it's full speed. Running wonderfully since Mid February.

Lower cost than others of its kind. It's significantly smaller than I was expecting, and the heat sink covers every bit of usable space for exceptional cooling.
