Dual-Port PCIe Gigabit Network Card 1000M PCI Express Ethernet Adapter with Intel 82575/82576 Two Ports LAN NIC Card for Support PXE for Windows/Windows Server/Linux/Freebsd/DOS with Low Profile

Nice piece of hardware for a firewall build using free BSD Unix. Works as advertised by seller. Is indeed compatible with Linux, free BSD Unix and Windows. I ordered 2x more for a backup build and to have as a spare, just in case.

I have written device drivers for several Ethernet chips. Intel Ethernet chips are my favorite. This product does not disappoint. Solid performance.

I have had a series of problems downloading large medical image files - typically about 1 gigabyte zip files with DICOM images using an 8930 Dell with Windows 11. After a recent Microsoft Windows upgrade - all downloads were failing. I have used up the PCEI X16 and one of the PCIE X1s with a 2 slot video card, and used up the PCIE X4 with a USB-C thunderbolt card. I needed to handle 500Mbps up and down symmetric in the remaining PCIE X1 slot. This card was one of the few PCIE X1's with this level of performance claimed. The drivers had a great interface and installed without difficulty. The result - I have my 2 slot video card, by USB-C card and - this card totally solved the download problems. Great product!!!

I built out a new PFSense box to replace the fanless microcomputer I had that died in a lightning strike. I had several TPLink 2.5 Gbit cards laying around, but to my chagrin, PFSense wouldn't recognize them. And looking online, it seemed that I wasn't the only one with this problem. I did find that it played nicely with Intel-based network cards such as this one. One quick order away, and my new firewall box is up and running.

Item is defiantly plug and play, easy to install and get going.... Looks really nice seems to be good for internet and file transfers to and from my server, appears to be functioning at full speed to and from the file transfers.

When I installed it initially, it wasn't recognized by Windows 11. After setting the BIOS configuration for the PCIe slot from "Auto" to "Gen3," it is now recognized and works fine.

I put this card in a used small form factor PC I bought online using the included SFF plate. I installed Proxmox onto the PC and created an Opnsense virtual machine to act as my home router. I needed this NIC to add extra ports for my WAN and LAN interfaces. I used PCIe passthrough to bind the NIC to the VM in Proxmox. Once I had Opnsense set up, I've been able to get gigabit or higher (~1.2Gbps) speeds both locally (using iperf3) and with speed tests over my fiber internet. I'm now getting faster speeds than the "traditional" gigabit router+wifi I was using before. Very happy with this card.

It was great when it worked but after a month mine died and stopped negotiating at 1GB
