Syba Dual 2.5 Gigabit Ethernet PCI Express PCI-E Network Controller Card 10/100/1000/25000 Mbps RJ45 LAN Adapter Low Profile Bracket, SD-PEX24066

Used in both Windows 11 and Linux (Fedora) machines. Both recognised the hardware on boot with no firther action or configuration required. One machine has a slimline form factor which required changing the bracket over to the supplied SFF bracket. This involved two screws being removed and reinserted. Performance has been well within expected parameters. No attempt has been made to bond the cards though no expectation of this protocol was expected.

Work as expected with claimed speeds, there good value too

Seems to work ok, was sceptical it could provide dual ports at full 2.5GbE - but it's on a homelab server and it's two ports for redundancy, so does the job. Not had any issues with it this far (on Proxmox).

I've tested Pfsense - not working no driver Opensense - not working no drivers Windows - working OpenWRT - working out the box. Ubuntu - working Unraid - working

Works fine apart from wol isnt working on my Z390 Aorus Master My old Intel I350-T2 wol worked fine I have had to enable the onboard i219v for wol until i can find a fix Update with regards to speed A single nic gets 284MB/s via Windows SMB Two Nic's with Two PC's gets 366MB/s (2 x 183MB/s) via Windows SMB It wasnt a drive speed limit I used an Intel 800P 118GB Optane Drive as the test device I dont have another PC with 2x2.5 Gigabit Nics so cant test SMB Multichannel on them It may be better to wait for someone to release a PCIE 3.0 X1 Solution With Regards to WOL I contacted Syba and here's the reply This multi port NIC does not support Wake on Lan.

It does what is in the description, Dual 2.5 Gigabit works with pfSense perfectly.

I don't know why this has to cost so much but it works, easy to install and setup. However, if you have or intend to upgrade to windows 11 it will NOT work, and I cannot find an updated driver from manufacturer which is pretty pathetic considering windows 10 is being discontinued !!

Bought because I needed two extra ethernet ports on a 2019 Mac Pro. The card has an Aquantia chip and system profile showed it as an ethernet card, however network preferences showed it as a serial card (dial up modem) which was weird. Couldn't really get further than that. Probably more a driver fault than the card. The card came with a shiny round object called a Ceedee Rom which wasn't much use. No link to driver from manufacturer. The Aquantia chip is compliant with MacOs so shouldn't have really been an issue.

So far so good, data transfer at reasonable speed.

Funktioniert soweit unter Win7 und ist damit eine sehr günstige Erweiterung um 2 Multi-Gigabit-Anschlüsse. Vor der Installation muss ggf. der Ausschnitt des Slotbleches mit einer kleinen Mettallfeile bearbeitet werden. Ohne leichtes Anschleifen passte die Karte nicht sauber durch das mitgelieferte und bereits verschraubte Slotblech und passte so nicht in meinen Rechner.

Using this dual port card in a PC running Proxmox 7.3 and OPNSense 22.7.9. I passed both ports as virtio Network Devices from Proxmox to OPNSense. It worked right away and has been stable and solid since then (over a month running 24/7).

I have three of these in a Proxmox cluster of machines, and all of them have worked out of the box with no issues. Repeat iperf3 tests has them pushing full speed without complications.

I installed this on a windows computer at first, and had to fight with the drivers a bit to get it working as expected. I later installed Proxmox VE onto the same hardware, and was pleasantly surprised when both NICs were recognized without needing to install any drivers. On both Windows and Proxmox, the NICs performed at advertised speeds. I'm impressed with how this has performed for the money.
