5Gb Base-T Network Card, Realtek RTL8126 Controller, NICGIGA 5G PCIe Ethernet Adapter Support WOL, 5Gbe RJ45 Port NIC Card, Windows10/11/Windows Server/Linux

No fuss with windows 11. Installed the card and it just works. Purchased the 2.5gb model and speeds are as advertised. I also like the black finish since I have a black case and motherboard. Very inexpensive card. I can’t speak to the longevity of the product since I haven’t had it that long.

Out of the box this was not running at the 2.5Gb speeds (even though Windows reported it as running 2.5Gb) it was staying around 900mb with iperf3 test between 2 other machines on network that both have 2.5Gb NICs. Using the QNAP 2.5Gbe unmanaged switch for 3 PCs that all have 2.5Gbe NICs. They are segmented on their own VLAN coming from pfsense firewall appliance which also has 2.5Gbe. After updating the drivers from the Realtek site as per the pamphlet that came in the box along with a small form factor screw driver and 2 screws (using case screw to match black aesthetic) and the 2 I/O plates, then it unlocked the full menu in the interface's controller properties. Also was getting closer to the 2.5Gb speeds on local network, RDP feels smoother and stable connections without drops. There is some irregularity in the iperf3 tests though. Not getting the irregularities from 3rd PC to main PC so not sure if it's driver related or just an issue with the Realtek chipset of this card. Overall though satisfied with the price to performance and hope there will be future driver updates, not counting on it though. For what I need it to do, be a stable RDP connection it seems to be holding strong and helps not feel laggy like it did with the default 1Gb port on the X370 Taichi Mobo. This is an improvement. If you do want a blacked out PCB and the bright green LED isn't visible while doing work then this is a good 2.5Gbe card. Also make sure you get the latest driver from Realtek, out of the box is not fully unlocked. Happy packets :)

It's fast and works great. easy to install comes with low profile bracket (Thank you!) and even a little screwdriver that was too small to break the screws loose so you might still need a bigger one. everything nicely boxed and extra mount screws, They really packaged this well. I am impressed! This turns my older Dell into a streaming box, saving my old PC for a good cause.

It works at 5gig but ONLY if you install the offical realtec driver. Sticker to download driver on the bracket has a typo so never works. Nothing a quick search didn't fix. Has really good throughput when paired with a 5gb SFP in my Cisco Meraki switch. Does run hot but the heat sink helps

Card works well but doesn't support port trunking under Windows 11 Home/Pro Environment due to Intel disconntituing they "Port Teaming" function after Windows 10. Haven't tried it in Server or Windows 10 OSs. Supports Jumbo Frames Slot alignement is right on and installation is easy. Doesnt seem to heat up much.

I'm amazed by this NIC. For as inexpensive as it was, I expected a generic looking corrugated cardboard box with inkjet level labeling with the card wrapped in nothing but an antistatic bag, if that much. Instead I got a very well packaged card with antistatic foam, a low profile bracket, extra screws for the bracket, and an antistatic cover for the slot connector. In addition to the great packing, the card looks spectacular, easily nice enough for even the most appearance conscious to have in their windows showcase. Even the brackets are painted very nicely in black. The heatsink is attached by screws, not the cheap pushpins or soldered pins, so it's easy to clean up if needed. The surface of the back of the card is coated such that it seems dust would clean off easily, though I have no way to test that at the moment. The PCB is good quality, and it looks like it would be reliable for a good, long time. If only they made 10Gb NICs...

I bought this 10GbE Base-T adapter for my OPNsense firewall. It worked perfectly at first and was immediately recognized by the system. Performance was great for the first few months. After four months, my firewall suddenly stopped processing traffic. The card is still detected correctly by OPNsense, but there are no link lights, and it will not recognize any connection. I am very disappointed in the quality of this card. It worked well at first, but it failed far too quickly. Consider this a warning if you plan to rely on it for more than a few months.

This little PCI card packs a nice punch! I’m in the process of re-wiring and redoing my network setup to prepare for an internet upgrade in the future. I’m currently at a 1GB speed but plan on updating to 2.5GB later. Easy installation and works with the drivers that Windows 10/11 finds for you. It will boost your current speed as well. I was getting around 700MBPS on average on my 1GB Ethernet port built into my ASUS motherboard. Once I starting using this Ethernet card, my speeds are consistently close to max. I’m getting around 950MBPS consistently now! I bought two of these so far and highly recommend it if your Internet speeds are more than 1GB and you want to utilize all that extra bandwidth. Or if you have 1GB speeds and your current Ethernet port is not quite getting its max

In case you don't want to read the full review the short version is: Good card, worth the money, fully recommended. The problem: The first picture shows the problem: a 1Gbps connection that only reaches just over 300Mbps, with a wired connection. Having checked every piece of equipment between modem and motherboard, including running a CAT 7 cable directly between the two the problem was finally identified as a dodgy Intel chipset on the ASUS B550-F motherboard. In other words the onboard LAN was just unable to deliver the full broadband speed - and had been delivering substandard speeds for some time. The solution: pictures 2-4: a NICGIGA 2.5Gbps PCI-E card with a Realtek chipset. Why this card? Well, simply put, it has a black backplate that fits in with the motherboard's black backplates. I know, not the best reason but it also has a known chipset, a decent heatsink on the main chip, an handle over the 1Gbps bandwidth, future-proofs to a certain extent and is at good price point. (A quick note about the future-proofing: a 1 Gigabit connection can potentially deliver over 1Gbps - up to 1.3Gbps - whereas a 1Gbps card stops at 1Gbps. This card is 2.5Gbps and so will handle over 1Gbps and provides some future-proofing for when the next major speed increase comes in.) Install: was really simple: unscrew a backplate, install the card, screw in the card, close the case and plug in a CAT 7 cable bought at the same time - KINBETA high speed 10Gbps 2 metre CAT 7 flat braided cable - and switch on PC. See pictures 6-8. The result: picture 9 shows the result. As soon as the PC started the card was recognised, no driver download was needed. The download speed jumped from 321.5Mbps to 925Mbps (picture 9) solving the problem in a most elegant way. It is interesting to note that the ping was 9ms both before and after upgrading the NIC and upload also remained the same - the 52Mbps which was the expected speed and initially highlighted the problem. For those with a small form factor PC it is worth noting that a smaller backplate is provided (see picture 5) as well as a screwdriver and two screws. Overall very happy with this purchase it solved the problem at a reasonable cost and I can feel the difference the higher speed connection makes. Definitely recommend this card.

Eingebaut und hat direkt funktioniert. Meine 2gbps kommen ohne Probleme durch.

Le produit est Bon. Pas hyper simple à installer pour ce qui concerne les Drivers sous Windows 11 mais en insistant, la carte est reconnue. Les débits sont conformes, jusqu'à 650Mo/s. Stabilité OK. Pas de dégradation après 1 an d'utilisation.

Instalar y utilizar. 0 problemas y tasa de transferencia sostenida.

This runs perfect in my pc. My internet connection is stable and runs at full speed. I even get the 2,5gbs intranet connexion from my router. My internet plan is only 100mbs so that doesn't benefit of the full 2.5gbs obviously but maybe in few years I'll get an optic fiber connection that will take advantage of that pciE card. This was easy to install and has no Cons or whatsoever.
