TRENDnet 10G PCIe Network Adapter, TEG-10GECTX, Convert a PCI Express Slot Into a 10 Gigabit Ethernet Port, 802.1Q VLAN Tagging, Windows and Windows Server Support

Working well and stable on a Windows 10 machine, connecting at 10gbit without any issues. SFP+ transceiver is Ubiquiti 10G going to Ubiquiti Enterprise 8 PoE switch SFP+ port, same transceiver. Simple plug and play with Windows, but user reviews here are accurate, download the Marvell AQN-100 drivers and there is a firmware, which can be accomplished in Windows. Once driver is installed it will be ID'ed as "Marvell AQtion Felicity Network Adapter" ... everything working seamlessly, much easier managing files on the home environment with the speed boost from 1g to 10g. Its an extremely compact card (and heatsink) compared to the Mellanox ConnectX3 which was having stability issues installed in the same box.Tip...Download the drivers and firmware update first before installing, Windows didn't know what it is for me* iPerf3 results showing ~7-9gbit consistently to my 10Gbit enabled Synology NAS** Received hardware v3.0R

Great inexpensive cards. I'd like to echo what another review said and download the latest windows drivers from the Realtek website, do not use the drivers loaded by windows 10 nor the drivers on the Trendnet website. This resolved 1 of 2 of my windows issues. The second issue, though not related to this card, but maybe it will help others, is that I had to remove software was called cFosSpeed that was automatically installed by MSi. Once I did both of these things I hit my Gb speed up and down on my fiber connection. Lastly, I have these cards in 3 separate operating systems including Win10, Ubuntu, and Unraid. Ubuntu and Unraid accepted them without issue and correctly installed the right drivers, the little fiddling required with Win10 resolved those issues. I'll buy these again if needed!

Excelente equipo.

Worked well, plug and play. Came with a driver disc but Windows was able to update the driver before I could open Device Manager.

What can I say, it works as intended. I've got 2 of these: one is in an Ubuntu 22.04 server (an old 4770 i7 machine) and the second and Arch Desktop (a ryzen 3900x). Both recognized the cards immediately and set their speeds appropriately with auto-negotiate enabled. Both machines are connected through a 10g copper port switch connected to an OPNsense router (1520 XeonD) with a 10g port.People trying to speed test these with file transfers are going about it the wrong way ad will never see the total throughput because of drive read/write speeds and protocol limitations of the chosen share method (i.e. SMB).The easiest and truest method to test is to run iperf3 as a server on a machine with a 10g interface, on the second machine run an iperf3 test as a client to your machine. BUT that will not really give you the actual result you want, as standard iperf3 tests are run as a single process and will probably cap out around 2-4 gigs. You need to run the client with the -P option to enable more processes, I typically use 10.Example:on the server end:iperf3 -son the client end:iperf3 -c (ip of the server) -P 10iperf3 -c (ip of the server) -P 10 -RThat gives me the output that I would expect to see, typically in the 8.4 - 9.4 gig range. Also be sure to run it in reverse as well with the -R option the second time.The cards work exactly as intended for 10g, though admittedly I have not tried 2.5g or just standard 1g because I haven't the need to. And 5 gig is incredibly uncommon to find so I won't bother with it.I've attached 3 screenshots to show you the results of the 3 iperf3 tests I mentioned. The first pic is if you run iperf3 -c (ip of server) and caps out at 3.73gsecond is iperf3 -c (ip of server) -P 10 and caps at 9.34gthird is iperf3 -c (ip of server) -P 10 -R and caps at 9.37gBTW I should note that I'm not actually using Cat6a for any of these machines. I'm actually using standard cat5e, but the lengths are less than 10 feet. If I had to go longer or started to notice issues, I'd up it to cat6a but it's not always necessary. Just an FYI
