Gigabit Dual NIC with Intel 82576 Chip, 1Gb Network Card Compare to Intel E1G42ET NIC, 2 RJ45 Ports, PCI Express 2.1 X1, Ethernet Card with Low Profile for Windows/Windows Server/Linux

Used two of these - one in a pFsense box and one in an OpenMediaVault box. The pFsense box had no problem recognizing it. I backed up the existing pFsense configuration, pulled the old quad NIC Intel board, and replaced it with one of these (the quad NIC Intel board was being freed up for use in a ProxMox VM machine). I edited the pFsense config XML and replaced the existing WAN, LAN, and VLAN IDs to the old quad NIC board with the IDs for this new board (I was only using 2 of the 4 interfaces on the quad NIC, as I've resorted to using VLANs rather than physical NICs to isolate LAN, IoT, and Guest networks). I was able to restore the pFsense box with the modified backup config XML and it rebooted with no problem, showing gigabit speeds on both the WAN and LAN side. The second one of these devices I installed in an OpenMediaVault NAS, and the Intel NICs on this board showed a significant speed increase over the Realtek NIC on the motherboard; transfer speeds from the OMV box to a TrueNAS VM running under ProxMox showed a speed increase of about 600mbps from the Realtek NIC to 900+mbps using the newly installed Intel NIC. Quite happy with my purchase - I purchased a third one which will likely find its way into another pFsense build for a family member.

Works great, no issues at all. Recognized by windows and linux server. Fast.

Working great so far in an old pc repurposed as an opnsense firewall. Installer found and configured both ports with no trouble

decent, runs on debian

1 Gbe is pretty slow these days but being an intel NIC it has wide compatibility so you don't run into some of the issues you can run into with other brands like realtek on FreeBSD. Great replacement for a SuperMicro server whose NIC died on me recently.

Simple dual Intel NIC for standard or low profile systems. I'm using it for pfSense. The driver used is igb (iflib for pfSense) version. Works without any special install for windows and linux. It uses the the standard 1gig speed. For only $25, the value is perfect.

No issues with this NIC. Works great for expanding a VM server's available interfaces. Worked on a Windows Server and a BSD Unix server.

This dual-port Gigabit Ethernet card is a practical option when you need more wired network interfaces. The Intel 82576 chipset is a good reason to consider it, because Intel NICs are generally well-supported in Linux, Windows, and many router/server environments. The low-profile bracket is also useful for small-form-factor builds. This is not a 2.5G or 10G card, but for firewall, router, Proxmox, Linux server, or general dual-LAN projects, Gigabit is still very useful. I liked this better than using random USB Ethernet adapters because PCIe NICs tend to be more stable for always-on systems. I was satisfied with the card.

Really easy install and perfect working order.

Works great in my ESX 8.0.3 server

happy to get this network card i recommend this

Buyer beware... H!Fiber Gigabit 2 Port NIC - Diagnostic Report Amazon ASIN: B07KG3R2RF Date: 2026-07-03 ISSUE: Card advertised as "Gigabit 2 Port NIC" with "10/100/1000Mbps" capability, but both ports negotiate 100Mbps maximum. EVIDENCE: 1. Subsystem vendor is NOT Intel: Subsystem: Beijing Sinead Technology Co., Ltd. Device 0308 (Genuine Intel cards show: Subsystem: Intel Corporation) 2. Port 0 (lan0) firmware only ADVERTISES 100Mbps: Advertised link modes: 100baseT/Full (Missing: 10baseT/Half, 10baseT/Full, 100baseT/Half, 1000baseT/Full) 3. Port 1 (wan0) advertises all modes including gigabit but still negotiates 100Mbps only: Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Speed: 100Mb/s 4. Both ports support gigabit at the hardware level: Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full 5. Testing methodology: - Multiple Cat6 cables tested - All cables verified gigabit-capable with other devices - Switch ports confirmed working at 1000Mbps with other devices - Same cable + same switch port = 1000Mbps with other device, 100Mbps with this NIC 6. Speed test through NIC: 91 Mbps down / 91 Mbps up ISP speed (tested from another device): 333 Mbps down / 130 Mbps up NIC is the bottleneck. 7. Firmware version: 1.63, 0x800009fb, 1.791.0 Driver: igb (Intel kernel driver loads, confirming I350 chipset) CONCLUSION: The card uses an Intel I350 chipset but is manufactured by "Beijing Sinead Technology Co., Ltd." with defective EEPROM configuration and/or substandard analog components. The product does not deliver the advertised gigabit capability on either port. This constitutes a product that does not match its advertised specifications. SYSTEM TESTED ON: - Debian 13.5 (Linux 6.12.94) - Acer Aspire AX3400-E3212 - PCIe link: Speed 5GT/s, Width x4 (full I350 specification) If you need 1000 Mbps from both ports, look elsewhere.

only one port work at a time , never buy , waste of money
