10Gtek 10/100/1000Mbps Gigabit Ethernet Converged Network Adapter (NIC) with Intel 82576 Chip, Ethernet PCI Express Network Card, Dual RJ45 Copper Ports, PCI Express 2.0 X1, Compare to Intel E1G42ET

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 distribution The 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.

I am using the network board in a running a pfSense firewall. It is providing firewall services for a medium size public library. Just a bit of volunteerism, so I appreacated the extremely rea.sonable price! Since the board features an Intel chipset, it is highly compatible with both pfSense (which does not like realtek network cards). The board has performed flawlessly.

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=0x00 vendor = 'Intel Corporation' device = '82576 Gigabit Network Connection' class = network subclass = ethernet cap 01[40] = powerspec 3 supports D0 D3 current D0 cap 05[50] = MSI supports 1 message, 64 bit, vector masks cap 11[70] = MSI-X supports 10 messages, enabled Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] cap 10[a0] = PCI-Express 2 endpoint max data 128(512) FLR link x1(x4) speed 2.5(2.5) ASPM disabled(L0s/L1) ecap 0001[100] = AER 1 0 fatal 0 non-fatal 1 corrected ecap 0003[140] = Serial 1 6cb311ffff1b17c0 ecap 000e[150] = ARI 1 ecap 0010[160] = SR-IOV 1 IOV disabled, Memory Space disabled, ARI disabled 0 VFs configured out of 8 supported First VF RID Offset 0x0180, VF RID Stride 0x0002 VF Device ID 0x10ca Page Sizes: 4096 (enabled), 8192, 65536, 262144, 1048576, 4194304 igb3@pci0:3:0:1: class=0x020000 card=0xa03c8086 chip=0x10c98086 rev=0x01 hdr=0x00 vendor = 'Intel Corporation' device = '82576 Gigabit Network Connection' class = network subclass = ethernet cap 01[40] = powerspec 3 supports D0 D3 current D0 cap 05[50] = MSI supports 1 message, 64 bit, vector masks cap 11[70] = MSI-X supports 10 messages, enabled Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] cap 10[a0] = PCI-Express 2 endpoint max data 128(512) FLR link x1(x4) speed 2.5(2.5) ASPM disabled(L0s/L1) ecap 0001[100] = AER 1 0 fatal 0 non-fatal 1 corrected ecap 0003[140] = Serial 1 6cb311ffff1b17c0 ecap 000e[150] = ARI 1 ecap 0010[160] = SR-IOV 1 IOV disabled, Memory Space disabled, ARI disabled 0 VFs configured out of 8 supported First VF RID Offset 0x0180, VF RID Stride 0x0002 VF Device ID 0x10ca Page Sizes: 4096 (enabled), 8192, 65536, 262144, 1048576, 4194304

In my homelab, I have a pretty robust server based around Proxmox 7.1, an AMD 5950X and 128GB of RAM. It's a sweet little playground. I wanted to play around with virtualized firewalls, particularly PFSense. The cheapest way I could find to do it was by adding NIC's to my existing server. I selected this dual NIC primarily because it used an x1 PCIe interface. My mainboard has two of these slots. The 4 port version is an x4 PCIe and my mainboard has none of these, meaning I'd have to use the x16 slot. I generally prefer to reserve my higher end x16 PCI slots for more capable hardware, not a basic 1G multi-NIC. Install was standard PCIe, about as simple as it gets. I read the reviews indicating compatibility with Proxmox and I can attest that it works well in my 7.1 build. I had the typical issue where Linux's dynamic network interface monitoring feature jacked up my interface name and bridge configuration. Easily fixed with a trip to /etc/network/interfaces though. (And to be sure, this is a Linux issue, not a hardware one.) I've had my setup going for a few months now with no troubles. I don't know much about this network card, such as who makes it or where to get drivers that I didn't need in Proxmox. That hasn't seemed to matter. Oh, and if you're interested in virtualized firewalls, I'd encourage you to explore it. I've had a lot of fun with PFSense so far.

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!

I picked up this card for use with an older ESXI host. It was recognized and worked great but I didn't realize that the card is not supported in v7.0 and above (I was running 6.5 previously). Where you don't need to use this latest version or use another supported OS I recommend it. I'll likely end up putting the card in a pfSense box instead which is another great use for these. Quick note: Avoid Realtek NICs in general but especially in pfSense and VMware.

A good ethernet card, but it's an older chip and Windows 10 and 11 doesn't support the drivers, but what's really well with the linex, I did find some drivers on the Dell website for Windows 10 that I used in are working really well

First, let me say that I'm an IT professional with over 30 years of experience. I know what I'm doing when it comes to building computers and firewall systems! I bought these cards after reading that other buyers had used them with pfSense without issues in the reviews. Unfortunately, none of mine would work out of the box with pfSense, OPNsense, IP Fire, or any other BSD or Linux based firewall I've tried (I tried 7 in all). I've tried all 3 cards I bought in 3 different computers, so I know it isn't the motherboard that's at fault. I have a hard time believing that all 3 cards I bought are defective, but it sure looks that way. If these cards don't work in a Windows box, I'm sending them back! I was going to try loading the drivers included in the box, but the driver CDs don't work, either. I've tried all 3 of those in 3 different drives on 3 different computers. Complete waste of my hard-earned money! Edit: After leaving my review above, I was contacted by the seller. They were apologetic that the NICs didn't meet my needs and offered a full refund, which I gladly accepted, without trying them in Windows. We made arrangements for me to ship them back, and I was refunded my money once the cards arrived. I did have to pay to ship the cards back, but I'm out a LOT less than I was before (less than the cost of one card). I will not hesitate to buy other products from this seller again. I must give them kudos for doing their best to rectify the situation! I appreciate the integrity this shows on their part.
