Syba Dual Port Gigabit Ethernet PCI Express 2.1 PCI-E x1 Network Adapter Card (NIC) 10/100/1000 Mbps Card with Realtek RTL8111 Chipset, 2 Port (SD-PEX24041)

Great in my Windows server 2012R2 HyperV. works with almost ALL virtual OS. we are using Linux, Unix, Windows in the VM environment.simply works. windows has already got the drivers for it, so install is very extremely easy. If you have PCIexpress 1.0 (the smallest one) and higher, no worries, this card works for ALL of them. buy it you will love it..

This replaced the failing NIC on my motherboard and have been faithful to me since. They both run at full 1Gbp/s and I use one at the default DHCP setting and the other as a static setting with Google's DNS for redundancy in-case my DHCP fails or my ISP's DNS should fail. This is a PCIe 1x card which will work snuggly into any free port even if you are doing a multi-GPU set up.

Works quite well to add zones/networks to a Sophos UTM network security appliance/server. Good speed/throughput on both ports. Didn't have an issue with install or setup, and both cards (I purchased 2) worked out of the box. Couldn't be more pleased with the purchase.

Spent 5 hours to get this card working with ubuntu 16, no luck. Appears that the recommended driver has a memory leak. Card will work correct for the first couple of packets and then degrade drastically. End game I settled for an Intel PRO/1000 Pt Dual Port Server Adapter. Works great! 5 hours I'll never get back... thanks Syba. Beware of this card as there is no RETURN! Questioning my Amazon Prime subscription.

Popped into my old Dell server, installed drivers and we're up and running with two extra gigE ports. Running under Windows 7. Have several VMs sharing this card via VMware Player without issue. Haven't speed tested it, but I've got it watching a port mirror on my router which sees ALL of my LAN traffic and it's keeping up just fine, so for even causal networking chores I suspect it's just fine.

This is just what the doctor ordered. If you are looking for a Gigabit Ethernet card with perfect Linux compatibility, look no further. No fuss and no mess. It just works. Unfortunately many of the other Gigabit Ethernet cards have problems under Linux (mostly due to a bad RT8169 driver), but this one works perfectly.

Product works as advertised, meaning it's a NIC that does NIC things. Does -not- work with ESXi out the box, you have to attach drivers to the installer which was expected, however, PCI passthrough will not work at all regardless of driver version. Additionally PFsense didn't seem to like this NIC as well, even though it worked well with my other realtek card. I sent this back for an Intel nic just to remove the headaches.

I installed this card in a Lenovo TD340 running Hyper-V Server 2016 TP4 and it recognized it no issue and has worked perfectly. I actually passed the two ports directly to a VM running PFSense which also no issue with card. Speed has been amazing so I am very happy for the price.

Husband installed it into his computer. Works great. He has two internet lines coming into the house and there has been no issues with it, both internet lines are coming in and hooked up, it creates its own load balancer and manages both internet lines appropriately.

Mis en place sur un petit serveur escorté fonctionne parfaitement

Funktioniert einwandfrei (und treiberfrei) sowohl unter Linux als auch unter Windows.

Funciona muy bien, es lo que esperaba, trae un adaptador para colocarlo a la computadora

Una odisea para encontrar los drivers Linux. Menos mal que al final en el foro del sistema de Vmware los encontré
