2.5GBase-T PCIe Network Adapter RTL8125B 2500/1000/100Mbps PCI Express Gigabit Ethernet Card RJ45 LAN Controller Support PXE for Windows/Linux/MAC with Low Profile

Simple, plug and play, works as it should, nicely packaged.

Doing the job fine as far as I can tell.

Great. I've been using this on my desktop PC, and it's been flawless: it sends and receives data like a champ.

For those looking to make the jump to 2.5GBe this isn’t a bad choice. However as others have said only use the Realtek drivers that are available on the Realtek website. The windows driver version which are automatically installed are unreliable. The chap that mentioned the Qnap 10gb/2.5gb 6 port switch is not wrong but these issues appear to have been resolved in the new Realtek driver and connecting to one of the 10gb ports. Up until then I was occasionally having issues with it too. No matter which card you pick drivers are all quite new and the usual bleeding edge issues will apply.

This has hugely improved my wife Ethernet speed, her old motherboard has a slow connection speed and this has just worked. Windows 11 advice, don't need a driver, if it doesn't recognize the 1st time, go into network setting, advance setting and do a network reset, reboot system and it will just start.

Bought after the ethernet port on my motherboard stopped working and this took its place perfectly.

Fitted it and worked first time No problems

Installed on an AMD X570 board and Windows 11. I tried to run OOKLA speed test but it couldn't finish. I had already downloaded the RTL8125B driver from the realtek site so I then installed. It all worked perfectly. Getting 1160 MB download and 104 MB upload from OOKLA speed test now. I also have 3 Linux distros installed and all worked out of the box, no drivers necessary. Very happy with this card.

I recently purchased the 2.5GBase-T PCIe Network Adapter with RTL8125B chipset, and it has been a game-changer for my home network. This little powerhouse of a network card has made a significant difference in my data transfer speeds and overall network performance. Installation was a breeze, as the card fits perfectly into a PCIe slot on my motherboard. The drivers were easy to find and install, and I was up and running in no time. I was pleasantly surprised by the compatibility and stability of this card with my system. The most impressive aspect of this network adapter is, of course, its speed. The 2.5 Gigabit per second throughput is a substantial upgrade from my previous 1Gbps network card. I've noticed a significant improvement in file transfer speeds, online gaming, and 4K video streaming. Whether I'm transferring large files or enjoying lag-free online gameplay, this card has consistently delivered. The RTL8125B chipset seems to be doing a fantastic job in managing network traffic. I haven't experienced any connectivity issues, and it's been rock-solid since I installed it. It also supports various advanced features like Wake-on-LAN, which is a handy addition for remote management. Additionally, this network card remains cool and doesn't heat up excessively, even under heavy usage. It also features an efficient power management system, which is great for energy-conscious users. In conclusion, the 2.5GBase-T PCIe Network Adapter with the RTL8125B chipset is an excellent addition to any PC or server setup. If you're looking for a cost-effective way to upgrade your network speeds and improve overall network performance, this card is a solid choice. I couldn't be happier with my purchase, and I highly recommend it to anyone looking to make the leap to faster networking speeds without breaking the bank. Kudos to the makers of this fantastic product!

It Does the JOB!

Ayant un ancien PC que je voulais upgrader j'ai installé cette carte sur le port PCIEx16 libre de ma carte mère. Sur le port PCIEx1 cette carte ne pourra pas donner tout son potentiel. Temps d'installation 5mn, il suffit de la clipser dans le PCIE de la carte mère. Au moment du boot du PC vous aurez un message "Realtek PCIe 2.5 Gigabit Ethernet Boot Agent Press Shift F10" Cela permet d'accéder à quelques réglages de la carte, mais c'est très sommaire. En fait rien à changer sauf peut-être le temps d'affichage de ce message. Autant sous windows11 que linux (ubuntu) aucun driver à installer. La carte est immédiatement détectée et se connecte en 2.5Gb sous réserve d'avoir une box avec un port ethernet 2.5Gb. Sinon elle se synchronisera en 1Gb ou 100 Mb selon ce que propose votre abonnement internet. Les tests de débit faits sous Win11 montrent que j'atteins bien 2Gb (le max que peut donner ma box internet). Tests réalisés avec l'application speedtest téléchargée sur le store. Sous windows/linux pour être sûr d'avoir les derniers drivers il faut aller sur le site de Realtek, récupérer le driver en cherchant Realtek PCIe FE / GBE / 2.5G / Gaming Ethernet Family Controller Software. Au final une bonne carte qui permet d'upgrader son PC très facilement et de profiter des débits de sa box.

Instalado en un slot PCIx12 de una placa madre Asus. Windows 11 pro. Funcionó a la primera, sin instalar drivers. Rendimientos perfecto. Me da la velocidad máxima contratada en subida y bajada. Estabilidad perfecta. Muy buena relación calidad precio
