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

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!

This was an easy to install product that let me run my PC at the full 2.5gb/s I'm paying for. Keep in mind, speeds depend on Ethernet wire rating AND your Ethernet splitter rating (if you're using one). I've had mine for about a year now and it still works great and fits well.

Easy to install, worked with windows without installing drivers. Fast speed.

I couldn't be happier with this network adapter! It was incredibly easy to install—literally plug and play. I didn't have to deal with complicated drivers or troubleshooting, which made the whole process a breeze. Once installed, it worked perfectly. My internet connection has been fast and stable, with no drops or interruptions. Whether I'm streaming, gaming, or just browsing, it performs flawlessly. For the price, this adapter is a steal, and it’s been a great upgrade for my setup. Highly recommend it for anyone looking for a hassle-free, reliable network adapter!

Installed on a 2010 MacPro running Mojave. The card was recognised but would not connect to internet. The Realtek site has drivers for MacOS 10.7 (Lion) which is over 10 years old. I hope the seller and manufacturer clarify which OS this has been tested on. (4 stars because I see it runs well on PCs. Good device just not for most Macs)

Just what I needed. My fiber internet provider talked me into upgrading from 1 Gig to 2 Gig service, but I quickly found I needed some new hardware to be able to take advantage of the new speed. The 10/100 network cards in most PCs top out at 1 Gig, so you're throttled to a Gig no matter what speed the provider delivers to your modem. Oh, yeah, and I needed a new modem, too, but they provided that. A quick speed test confirmed I was still at 1 Gig before I installed the new card, but then it immediately jumped to over 2 Gigs. The new card required no setup or configuration, but I did need to go into Windows Device Manager and disable the old integrated card to keep it from conflicting. Easy. I liked that the new router included a CAT 6e cable, because you'll likely need to upgrade those, too. Overall, I'm happy with the new card.

I've been using this card for quite a while before writing this review and I can say for the cost, this card is worth it. I get a full 2.5Gbit when connected to a 10G network and the card has no problem with flaking out, dropping packets or getting squirrelly even over transfer that take sever days. The card keeps outputting like it's supposed to even under full load for extended periods of time. One thing I will note is that it runs extremely hot, so just make sure you have good airflow over the surface of the card and it will be fine. I am sure if you didn't have good movement of air you might run into a problem where the card overheats, but I never had this issue personally because I just made sure it wasn't crammed right up against another card and there was no problem! Hope you found this useful!

This fits the PCIe slot in my Dell SFF home lab perfectly. While Windows automatically picked up an older driver, I'd suggest downloading the latest Realtek Win10/Win11 Auto Installation Program instead. Just extract the .exe and update the driver manually by pointing it to that extracted driver folder. Performance is solid. It fully delivers on speed, consistently maxing out both my internet speed tests and local transfers to my NAS. Amazing value if you want to harness your 1+ gig internet connection.

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

Having got new broadband I was gutted to be restricted by my network card. This little number soon arrived from Amazon, was plug & play therefore i did not need additional drivers, Windows done all the work for me. I was soon at full speed with this great, value for money, NIC
