1.25G Gigabit Ethernet Converged Network Adapter (NIC) with Intel I350AM2 Controller - Compatible for Intel I350-T2, Dual Copper RJ45 Ports, PCI-E 2.1 X4

I was using Realtek cards with my pfSense build before, which FreeBSD has a lack of support for. My internet would constantly drop, etc. But this card works wonders with it, and haven't had a connection drop of quirk ever since. Perfect for a home pfSense build.

A bit pricey but works very well so far - recommended. Speed is as expected and it's easy to install.

This card is detected right a way in debian 11 and openwrt without any issues and it works great. It comes with two brackets and I was able to change the long one to mini one and fit this into my dell optiplex 7010 small factor pc which is now my router + nas in one box. I recommend this card.

Having had enough of using awful ISP provided routers, I decided to use an old Dell Optiplex to build a router based of OPNSense so needed an additional network port in the system. The card was a simple solution, cheap and easy to install and works perfectly with OPNSense. All setup and running and so much better.

Working under Ubuntu LTS 20.04 using the IGB Driver. The MAC refers to Beijing Sinead Technology Co., Ltd. in China not Intel Corp so maybe it's a clone of the 82576 chip and not genuine Intel hardware. LAG and VLAN working fine. As people have mentioned, trying to use full 4Gbps bandwidth causes a drop in speed, even though it's connected to a 4x@PCIe2 Slot as confirmed by the LSPCI report which gives 16GBps in each direction, it should have more than enough bandwidth to saturate.

Had troubles with connection dropping on my pfsense virtual machine. Turned out to be the Realtek Nic I was using. Swapped over and runs perfectly Easy to install

Perfect

Works with proxmox pass-through to a vm router / opnsense. Can't comment on the performance as i only have 70Mbit internet but processor usage is almost 0 while running a speed test so something is working well behind the scene and i assume it supports IOSRV for virtual environments. Not noticed an increase in power usage on my hypervisor either so that's a bonus.

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.

Simple à implémenter et efficace.

La tarjeta funciona genial y agrega puertos sin problemas formando un canal de 2 gbps (conectado directamente a mi router Netgear Nighthawk X10 R9000, en los puertos que 1 y 2 que son los que soportan agregación de enlace, con la agregación de enlaces configurado como dimámico LACP 802.3ad. El CD que traía con drivers no se podía leer bien pero de todas formas están anticuados. En la página de Intel me bajé los drivers actualizados para Windows 7: PROWinx64Legacy y todo genial

Had al meerdere intel clones geprobeerd in mijn pfsense router maar ze bleven maar problemen geven. Beetje sceptisch deze besteld en na installatie geen uitval gehad. Dus perfecte kaart.

La scheda e' qualitativamente buona, tutto corrisponde alla descrizione. Buone prestazioni, montaggio rapidissimo, nessun problema con i driver. Aggiungo il prezzo conveniente, molto soddisfatto.
