H!Fiber 2 Pack 1Gb PCIe Network Card, auto-Negotiation 10/100/1000Mb/s, Gigabit PCIe NIC with Realtek RTL8111H Chip, Single RJ45 Port, PCIe X1, 1G Ethernet LAN Network Card for Windows/Linux/MAC

Works decent would probably perform better with heat sinks and a fan

I've had no issues; works great. The low-profile bracket attaches easily, and fits low-profile cases, and i do get close to the full 1 Gbps speed during a large file copy. Not bad for $60.The last one got fried in a lightning strike that happened nearby; even behind a UPS. I guess the EMP on the network cables was too much for it.

Great product and a great price for dual ethernet port card. Unbeatable price on name brand part. Cant beat the quality.

I was trying to install VMware ESXi 7 on an old Dell XPS desktop system, but ESXi would not recognize the built-in NIC, and thererfore wouldn't complete the installation. After multiple failed attmpts to follow online and YouTube instructions on how to "inject" NIC drivers into the ESXi ISO, I gave up and decided to try a new card.I purchased the "Gigabit PCIe NIC with Intel 82574L Chip" since this chipset is actually listed in the VMware Hardware Compatibility Guide, and the Amazon description claimed it to be ESXi 7 compatible. I was pleasantly surprised that the card was identified by ESXi, and the installation completed without any problems.I can't speak about whether the other NICs on this Amazon page would work with ESXi 7, mainly because the descriptions for some of the cards do not explicitly mention being ESXi compatible. But I can definitely recommend the one with the 82574L chipset based on my success... plus the price is right!

The adapter works and negotiates 1Gb speeds; however, when using it under both pfsense and opnsense, the adapter will lock up the machine occasionally, about once a week, causing my entire network to go down. I've tried two of these adapters and both have the same issue. Replaced with a genuine adapter and the problems are now gone. Avoid, don't waste your money.

Easy to install and drivers already built into Debian

Our Dell XPS 8930 at church that we use for streaming has the Intel "killer" ethernet E2500 chipset in it. Worked good for a long time, but then all of the sudden it would start dropping out during a service. It would disconnect for a few seconds, then reconnect. It would do it quite often. Tried updating the drivers and trying other tweaks found with net searches but no luck.We switched to wifi but that was causing issues too, the video would stutter or freeze from time to time. Probably because too many devices were connected to it?So decided to try add-on card in the computer. The X4 slot was being used for a video capture card and the X16 for a video card. It has 2 X1 slots but I think the video card covers one of them.After the fiasco with the E2500 was hesitant to go Intel again but the I210 chipset gets good reviews so got this one. Thankfully was able to squeeze this into the open X1 slot and so far so good, our streaming connection appears to be solid now and speedtest is reporting 200/200 which is what our internet service is. Even changed the settings in OBS to get a better picture and it handled it like a champ.

Perfect as advertized.
