10Gtek 10/100/1000Mbps Gigabit Network Card (NIC) with Intel I210AS Chip | Ethernet Converged PCI Express Network Adapter | Single SFP Port | PCI Express 2.1 X1

When building a Linux system the last thing you want to deal with is weird drivers. So I always look for Intel or Broadcom chipsets in ethernet cards. Intel chipsets in particular are pretty much guaranteed to work. Most of the servers I build have Intel I350 ethernet cards for a reason. They're fast, reliable, and use the rock-solid "igb" driver that you can be absolutely certain will be included in the stock kernel from any Linux distributionThe I350 controller chip has been in production since 2011 and Intel plans to manufacture it through 2031. It's fast, reliable, inexpensive, and uses only 2.8W of power. Those features, combined with the high availability of the chip has made it ubiquitous on server motherboards. As a result it's extremely well supported by any operating system you might want to use.Thie PCI interface on the card identifies itself as being built by Beijing Sinead Technology Co. The ethernet MAC address has the correct prefix (98:b7:85) for Shenzhen 10Gtek Transceivers, which matches the name of the seller on Amazon. That's always a good sign; they're using properly assigned MAC addresses rather than just cloning some other card.The card appears to be identical to the I350 cards sold by Intel. The only difference is the price, which is less than half what Intel charges.I'll probably buy more of these in the future. Great pricing and like the other 10Gtek products I've purchased in the past it's a solid product.

This was a perfect replacement for my Proxmox system, the onboard nic was a realtek and started giving me errors. I wish I bought a two port version so I could play with opnsense, but I'm sure their will be opportunity later.

Not a technical review but my experience from being a sudo-tech. I have a TrueNAS only to host content for Plex. If Plex wasn’t a thing I would never have built two machines over the last seven years. The first one was dated two years ago easily so I had to upgrade. I bought a older MB but still lights out better than before- a ASRock B550 Pro4. What I didn’t know was that MB has a RealTek ethernet chip. I pulled everything in and all was well. I went to move data and my network started to drop. After seeing that I saw an error on the TrueNAS about the network. After researching the problem was the RealTek 2.5. I then bought an Intel 2.5 and found that those don’t have proper driver so that was returned. Then I found reviews about this 1G card and bought it. Immediately plugged in and worked with no extra effort from me. Moved big data files with no errors. I was relieved. How long will this last? I will see. I wish I could have gotten the 2.5G to work to stay up to date but that is fine. On to the next problem!

Very good product and working fine with pfsense and good performance with suricata IPS inline mode.pciconf -lcv #Output of pciconf command on freebsd.igb2@pci0:3:0:0: class=0x020000 card=0xa03c8086 chip=0x10c98086 rev=0x01 hdr=0x00vendor = 'Intel Corporation'device = '82576 Gigabit Network Connection'class = networksubclass = ethernetcap 01[40] = powerspec 3 supports D0 D3 current D0cap 05[50] = MSI supports 1 message, 64 bit, vector maskscap 11[70] = MSI-X supports 10 messages, enabledTable in map 0x1c[0x0], PBA in map 0x1c[0x2000]cap 10[a0] = PCI-Express 2 endpoint max data 128(512) FLRlink x1(x4) speed 2.5(2.5) ASPM disabled(L0s/L1)ecap 0001[100] = AER 1 0 fatal 0 non-fatal 1 correctedecap 0003[140] = Serial 1 6cb311ffff1b17c0ecap 000e[150] = ARI 1ecap 0010[160] = SR-IOV 1 IOV disabled, Memory Space disabled, ARI disabled0 VFs configured out of 8 supportedFirst VF RID Offset 0x0180, VF RID Stride 0x0002VF Device ID 0x10caPage Sizes: 4096 (enabled), 8192, 65536, 262144, 1048576, 4194304igb3@pci0:3:0:1: class=0x020000 card=0xa03c8086 chip=0x10c98086 rev=0x01 hdr=0x00vendor = 'Intel Corporation'device = '82576 Gigabit Network Connection'class = networksubclass = ethernetcap 01[40] = powerspec 3 supports D0 D3 current D0cap 05[50] = MSI supports 1 message, 64 bit, vector maskscap 11[70] = MSI-X supports 10 messages, enabledTable in map 0x1c[0x0], PBA in map 0x1c[0x2000]cap 10[a0] = PCI-Express 2 endpoint max data 128(512) FLRlink x1(x4) speed 2.5(2.5) ASPM disabled(L0s/L1)ecap 0001[100] = AER 1 0 fatal 0 non-fatal 1 correctedecap 0003[140] = Serial 1 6cb311ffff1b17c0ecap 000e[150] = ARI 1ecap 0010[160] = SR-IOV 1 IOV disabled, Memory Space disabled, ARI disabled0 VFs configured out of 8 supportedFirst VF RID Offset 0x0180, VF RID Stride 0x0002VF Device ID 0x10caPage Sizes: 4096 (enabled), 8192, 65536, 262144, 1048576, 4194304
