H!Fiber Gigabit 4 Port NIC with Intel I350 Chip, 1Gb Network Card Compare to Intel I350-T4 NIC, Quad RJ45 Ports, PCI Express 2.1 X4, Ethernet Card with Low Profile for Windows/Windows Server/Linux

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.

I'm using a pair of these Gigabit Dual NIC with Intel 82576 Chip on OpenBSD. Worked OOB. It's been running for about a month now. I've had no trouble getting ~1gbps saturation on these cards between machines tested with iperf or through the internet with various speed test sites.

Fast and absolutely compatible with my older motherboards.

Machine goes into power cycling and will not post with this card installed. Motherboard is a Gigabyte X299 Aorus Master. Without this card it operates properly. Sad that there is such a short return window for a non-working product.

Worked in my Nuc9 Extreme's like a charm... unlike my first attempt... wish 2.5 or 10Gb Base-T were affordable like this product is.

Works great.. no problems..

This is a review of four related products purchased here on Amazon.1. Klein Tools VDV826-703 Pass-Thru™ Modular Data Plug, CAT6, 50-Pack (ASIN B076PRM7W8)2. Klein Tools VDV226-005 Compact Pass-Thru™ Modular Crimper (ASIN B07R3GK9FQ)3. Soft Plastic Ethernet RJ45 Cable Connector Boots by Copapa (ASIN B07219KGC4)4. H!Fiber 1Gbe Ethernet Network Adapter (ASIN B074PPRQQK)I’m using CAT 6 UTP (23 AWG) that I bought from a local home center.1. I found the Klein Tools VDV826-703 Pass-Thru™ Modular Data Plug, (CAT6, 50-Pack) to be easy to use. This is my first-time using pass-thru connectors, and I have mixed feelings, but that’s not what this is about. The 23 AWG wires fit in snuggly but did require a bit of convincing to pass thru. They are more expensive than some others that are available, but I know these will work perfectly, especially with a same brand crimper.2. The Klein Tools VDV226-005 Compact Pass-Thru™ Modular Crimper did its job flawlessly. The insulation is held tightly in place, the crimp felt secure, and the pass-thru wires were cut perfectly flush. I still need to try this with cheap plugs, to see if they are cut just as flush, but these work great with their own.3. While I don’t usually use boots, I decided to give them a shot as they make the wires look more “finished”. I purchased the blue Soft Plastic Ethernet RJ45 Cable Connector Boots by Copapa. While they didn’t cost much, they were very soft and fit okay. I wish they were a little tighter around the wire, but that can vary from brand to brand. Overall, I’m happy with them.4. Once the cables were completed, I plugged them into a H!Fiber NIC (Intel I350-T4 chipset). They all fit nicely together, even with the boots. That network card is not the V2, and that was expected. The V2s are harder to find and there are no performance differences. The revision was made to fix a slight power surge during power-on. The network card performed flawlessly with pfSense and I was able to configure two LAGGs with LACP support. One to a Cisco managed switch, and the other to my cable modem (SB8200) but I’ll save those for a different review. This card is working perfectly.

I purchase several things on Amazon and was giving pretty in-depth reviews. From this point on, here's the new agenda…. if it works as advertised, is well made, meets or exceeds the description, is a value, and arrives in a fair amount of time, it will get a "star rating" equal to what my expectations were/are. If it doesn't meet these criteria, then I will most definitely and descriptively tell the short comings of the products and you as a consumer will not have to go through the trouble of buying the product without some background knowledge. If the sell pulls that item and relists under another description, I will put the exact same review on the seller's feedback page. Sellers have done this a couple of times in the past, and I was true to my word then as well as now. DR
