"I have the 10gbe M.2 form factor card, disregard all of this if you're considering one of the 2.5gbe cards.This card uses a Marvell/Aquantia ACQ107 chip. Don't expect Windows to have a driver for this.Setting up: Grab the newest driver from Marvell's "Public Driver Downloads" page. (You can just google your way there.) Your search category on the download page is "Marvell Public Drivers" - select your OS of choice and your part number is ACQ107. On Windows, you'll need to unzip the driver into a folder and point Device Manager's driver installer toward that folder manually.After setup, I've been getting intermittent disconnections that I can't seem to resolve. The card hits 10g speed while it's actually working, but it will lose connection for four or five seconds at a time, seemingly at random.[Update: Chip is overheating and shutting down. The short M.2 heatsink isn't enough to keep this thing happy without quite a bit more airflow than my machine has.]"

I installed this on a repurposed HP willow 2 motherboard with an AMD A10 chip running ZimaOS and it was recognized as 5G Ethernet device immediately. I needed at least a 2.5G solution, since my pcie was populated with a 10G SFP as I plan to use this machine as an OPNsense router on my 2G fiber network. I am very happy with this device since I now have room to upgrade my network in the future without the need to upgrade my hardwaretinkerton

Have not used it for extended periods of time, but seems to work correctly when combined with a USB4 or Thunderbolt4 port. It does get HOT, so don't put anything on top of it. Windows 11 driver worked just fine out of the box, but I did tweak some settings. I do this on all my Ethernet adapters.If your USB4 port is not also Thunderbolt, this device will not show up as a network adapter. It uses the Aquantia chip. It will show up as a USB device with no function.anthony w herbert

Was able to get this working for pfSense 2.7. You have to install the Realtek package. Try to do this prior to installation of the card or it’ll be impossible to get the packages (you need a working WAN port).1. Enable secure shell in Advanced settings and SSH as admin to your firewall management address2. Select 8 for shell and run “pkg install realtek-re-kmod” (the package installer will instruct you to do the following)3. Edit boot “ee /boot/loader.config”4. Add the two lines if_re_load=“YES” if_re_name=“/boot/modules/if_re.ko”5. Save file by pressing ESC and answering leave editor and save5. Reboot by typing rebootjustin

This is the only only 10Gb PCIe x1 NIC I could find but it works great so far. This works out of the box on Windows 11. I was pleasantly surprised to see a significant decrease in my loaded upload latency compared to the onboard NIC I've been using. It dropped from around 50ms down to 3ms. For some reason my loaded download latency increased from around 3ms to 11ms with this card but that's a trade-off I'm happy to make. With this I'm finally able to take full advantage of my 5Gb fiber internet.tandy norris
Works great with my MacBook Pro M3.
