2.5Gb PCIe Network Card with Intel I226-V Chip, 2.5GBase-T Network Adapter NIC, PCIe 3.1 X1, PCI Express Gigabit Ethernet Card for Windows 10/11, Linux Kernel 5.16.18/RHEL8.6, VMware ESXi8.0

I have an older PC that has been repurposed to be my NAS using Unraid. I purchased this to replace an intel based 2x1Gbps card that was running as an aggregated LACP bond. It took a little bit to learn how to get Unraid to make this the primary NIC, but that's not the card's fault (it wasn't really that hard, I am just not familiar with Unraid just yet). After installing the card and getting it connected to my Ubiquiti Unifi Cloud Gateway Max, I ran In iperf3 test to another Unraid system on the network. I am no network engineer, but I'm getting "close enough" to the advertised maximum bandwidth to make me very happy. My iperf3 results are below: iperf3 -c 10.0.20.21 Connecting to host <targetIP>, port 5201 [ 5] local <sourceIP> port 58840 connected to <targetIP> port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 282 MBytes 2.36 Gbits/sec 0 311 KBytes [ 5] 1.00-2.00 sec 278 MBytes 2.34 Gbits/sec 0 308 KBytes [ 5] 2.00-3.00 sec 279 MBytes 2.34 Gbits/sec 0 311 KBytes [ 5] 3.00-4.00 sec 278 MBytes 2.34 Gbits/sec 0 305 KBytes [ 5] 4.00-5.00 sec 280 MBytes 2.35 Gbits/sec 0 308 KBytes [ 5] 5.00-6.00 sec 278 MBytes 2.33 Gbits/sec 0 305 KBytes [ 5] 6.00-7.00 sec 280 MBytes 2.35 Gbits/sec 0 308 KBytes [ 5] 7.00-8.00 sec 278 MBytes 2.33 Gbits/sec 0 311 KBytes [ 5] 8.00-9.00 sec 279 MBytes 2.34 Gbits/sec 0 308 KBytes [ 5] 9.00-10.00 sec 278 MBytes 2.33 Gbits/sec 0 5.66 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 2.72 GBytes 2.34 Gbits/sec 0 sender [ 5] 0.00-10.00 sec 2.72 GBytes 2.34 Gbits/sec receiver I may try to set up jumbo frames (I don't know if that' still a good way to increase throughput, but I seem to remember 'back in tha day' it being one way to improve performance) but I'm not sure. For now, it gave me what I wanted: a very affordable and fast speed boost on my small home network.

Detected fine in an Asus AMD x570 motherboard. No windows 10 drivers automatically found. Unfortunately Intel's website makes it a bit harder than it should be to find drivers. Search for "Intel Network Adapter Driver for Windows 10". Version 29.1 installed without issue. I ordered a second one and will update review if there are any problems.

It was easy to install and comes with a little screwdriver so I could change the bracket for a small half height slot. Just needed to enable the PCI slot in the BIOS and it was seen by Proxmox and it works well with Ceph. It was recommended by Copilot and has worked well, better than the USB C 2.5Gb adapter. It was cheaper than the USB C adapter as well. Well packaged had a little cover on the PCI fingers, make sure you take it off before you try and install it. I works with HP and Dell SFF computers.

Fast delivery! This i226-V works great with my vm pfsense running on Proxmox. No issues setting up.

Prompt delivery. Easy to install intel drivers compatible. And not cost prohibiting.

Warning 2 of these cards do not appear in the Windows 11 Device Manager on my two Gigabyte B450 Aorus Pro Wifi motherboards. I contacted support which tried helping, but none of the bios changes they suggested fixed my problem. I then installed the 2nd card with the same results. They then suggested another PC. I installed a fresh copy Windows 11, updated it with all Windows updates and installed all the current drivers. Made the bios changes tech support suggested. Same results, the card never appears in the Device Manager. Life is too short. Requested replacement cards or refund. Contacted Amazon, they refunded my money.

The card installed easily and setup without any struggles on Almalinux (RHEL) 8 machine, but when I booted the same machine into windows 10, there was no readily available driver. I had to download the full driver set from the Intel website, extract the appropriate driver for intel 226V from the .zip file, and via windows device manager point it to the extracted driver. Then all was well. No driver link or instructions found on the XikeStor support link. I took off 2 stars since no windows installation information was provided by the seller.

Aprés 2 mois d'utilisation la carte est hs. les 2 premières semaines, aucun problème, débit très correct. Du jour au lendemain la carte se désactive. Puis plus rien. Je ne sais pas si il y a un SAV, mais je ne le recommande pas pour l'instant.

2.5Gbpsで大満足している者のレビューです。 ASUS PRIME Z390-Aで使っていますが、通信がとても快適になりました。

Works well under FreeBSD/TrueNAS Core 13.3 out of the box. No drivers required. Arrived well packed. The set contains a short and a long bracket, a screw and even a mini screwdriver that you can see on the photo. More than expected. I recommend the seller.

Works great to SFP converter box for internet with 2.5G link. Behaves better than Realtek in Debian, at least in my case. Haven't had problems with any of those reported 225/226 bugs so far.

Ottima scheda e funzionante con VMWARE ESXI in modalità plug & play senza fare altro.
