Dual PCIe 3.1 2.5GBase-T Network Adapter with Intel I225-V / I226-V 2500/1000/100Mbps PCI Express Gigabit Ethernet NIC Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket

I got a chance try this on Windows 11 and FreeBSD. Both worked like a charm.

Plug and play at advertised speeds.

Has been running rock solid in a PCIe 3 slot in an old Lenovo box and has been solid and reliable for OPNsense to use without fail. The NIC worked great with the FreeBSD based router OS, so drivers were already good to go. It is very nice to have 2 NICs only taking up one slot and this leaves my x16 slot open for other uses. I was able to test a full 2.5gbe connection/link and had no trouble at all. Great value.

DoA. Does not work. No Link, No Link Lights... First card wasn't seen. Changed slot, card was seen but then failed and went disabled with Code10. Updated Drivers and rebooted. Then, no link lights, no link at all. Swapping from a working Real Intel 1G NIC to this one, Win 10, Ent.Note: THIS ITEM IS NOT A TRUE INTEL CARD. It uses the same driver set, but it is a fake.Unfortunately, this card was sitting new in the box for a while before I tried this install so Amazon return date is gone...I am a network engineer by profession, do not buy this card. Stick to known manufacturers.

It worked well when put into a Dell server and didn't have any issues, even though it is not an enterprise-grade chip.

Use it in an old server for OPNSense and haven’t had a problem with it in the year or so that I bought it. No complaints

I installed this in my opnsense v17.1.5 firewall and it saw them right away. No need to install any new drivers, and my FW is now upgraded from 1gb to 2.5gb - used one for the fiber modem -which to be fair is only 1gb and one to my network connected to a 2.5gb switch.

Bought to replace a realtec nic in my unraid server. Realtec is tricky with Linux and obtaining correct drivers. This was 100% plug and play. Will only be buying intel from now on.
