With support for multi-gigabit speeds and advanced features, it delivers seamless networking experiences. OS Support Description This PCI Express controller with Base-T copper networking interface,provides compact, single-port integrated multi-gigabit (up to 2.5G) -MDI (Copper) standard IEEE 802.3 Ethernet interface for 2500BASE-T,1000BASE-T, 100BASE-TX, 10BASE-TE connections (IEEE 802.3,802.3u, 802.3ab). The Ethernet Controller I225 is designed for use on any mobile,desktop, workstation, value-server, or industrial designs that have critical space constraints. The I225 can also support Intel vPro technology onspecific Intel platforms and chipsets. The Ethernet Controller I225 also supports the latest time sensitive networking (TSN) features, along with best in class power management and Operating System Support Specification Compliant with PCI Express specification Revision 3.1(5GT/s) MDI(Copper) standard IEEE802.3 Ethernet interface up to 2.5Gb/s Complies with single port 1GbE RJ45 port (copper) Complies with the MDI standard IEEE802.3 Ethernet interface for 2500BASE-T,1000BASE-T,100BASE-TX,10BASE-TE application( IEEE802.3bz, IEEE802.3ab ,IEEE802.3u and IEEE802.3 ) IEEE802.3 Auto-negotiator IEEE802.3x and IEEE802.3z compliant flow control support with software-controllable RX thresholds and TX pause frames Automatic cross-over detection function(MDI/MDI-X) IEEE 1588 Protocol and 802.1AS implementation Supporting Time Sensitive Networking(TSN) Capabilities Support IEEE802.3az-Energy Efficient Ethernet(EEE),EEE is supported for 2500BASE-T, 1000BASE-T and 100BASE-TX.

No compatibility issues. Good value Review: Exactly what I needed - I purchased this NIC to bypass my motherboard’s integrated Realtek controller that was forcing my computer to be limited to 100mb/s network speeds. This NIC was very easy to install, and I was immediately able to see an improvement in speed as it auto negotiated true gigabit speeds with my switch. My ping dropped from 7 to 1ms, and streaming videos no longer freeze temporarily. Delivery was fast, and the contents were well protected. A great value for the money for the performance of this NIC. ## Features - PCI Express 3.1 :5GT/s Support for x1 width (Lane).The I225-V has been discontinued, and the I226-V will replace it. The two models have identical functionality. Compared to the I225, the I226 has improved error rates, offering better data packet stability over longer cable lengths and providing a more stable network connection. It also enhances the accuracy and stability of data transmission. Additionally, the I226 reduces active power consumption compared to the I225, making it more energy-efficient - Network Interfaces:Integrated MAC + BASE-T PHY. MDI (Copper) standard IEEE 802.3 Ethernet interface for 2500BASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-TE applications (802.3, 802.3u, 802.3bz, and 802.3ab) - Compatible for X1,X2,X4,X8,X16，Comes with low profile bracket - Support ESXI7.0/OPENWRT/UNRAID/PVE/WIN10/11/Linux.Support PXE function , Full Wake on LAN and TSN - 180 day worry-free warranty and friendly customer service. If you have any questions, we will help you solve the problem when you need it, and if it can’t be solved, we will provide a refund and no return is required. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BNHWZBCC | | Best Sellers Rank | #86 in Internal Computer Networking Cards | | Brand | ULANSeN | | Built-In Media | 1 x PCIe I225-V Single-2.5G Network card 1 x User’s Manual 1 x CD 1 x Low profile bracket | | Color | I225-Single Port | | Compatible Devices | Desktop | | Customer Reviews | 4.2 out of 5 stars 327 Reviews | | Data Link Protocol | 100BASE-TX Fast Ethernet IEEE 802.3z IEEE 802.1Qav IEEE 802.1Qbu IEEE 802.1Qbv IEEE 802.3br IEEE 1588 IEEE 802.3ad IEEE 802.3az - Energy Efficient Ethernet, IEEE 802.1bz 2500BASE-T Ethernet IEEE 802.3ab 1000BASE-T Gigabit Ethernet IEEE 802.3u Data Link Protocol 100BASE-TX Fast Ethernet IEEE 802.3z IEEE 802.1Qav IEEE 802.1Qbu IEEE 802.1Qbv IEEE 802.3br IEEE 1588 IEEE 802.3ad IEEE 802.3az - Energy Efficient Ethernet, IEEE 802.1bz 2500BASE-T Ethernet IEEE 802.3ab 1000BASE-T Gigabit Ethernet IEEE 802.3u See more | | Data Transfer Rate | 2500 Megabits Per Second | | Hardware Interface | Ethernet, PCI Express 3.0, PCI Express x1 | | Item Dimensions L x W x H | 2.83"L x 2.17"W x 0.71"H | | Item Weight | 40 Grams | | Manufacturer | ULANSON | | Product Dimensions | 2.83"L x 2.17"W x 0.71"H | | Warranty Description | 1-YEAR Warranty | ## Product Details - **Brand:** ULANSeN - **Color:** I225-Single Port - **Compatible Devices:** Desktop - **Data Transfer Rate:** 2500 Megabits Per Second - **Hardware Interface:** Ethernet, PCI Express 3.0, PCI Express x1 - **Item Weight:** 40 Grams - **Manufacturer:** ULANSON - **Product Dimensions:** 2.83"L x 2.17"W x 0.71"H ## Images ![PCIe 3.1 2.5GBase-T Network Adapter with Intel I225-V / I226-V 2500/1000/100Mbps PCI Express Gigabit Ethernet NIC Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket - Image 1](https://m.media-amazon.com/images/I/61rs64Imc-L.jpg) ![PCIe 3.1 2.5GBase-T Network Adapter with Intel I225-V / I226-V 2500/1000/100Mbps PCI Express Gigabit Ethernet NIC Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket - Image 2](https://m.media-amazon.com/images/I/51n8TNiv7lL.jpg) ![PCIe 3.1 2.5GBase-T Network Adapter with Intel I225-V / I226-V 2500/1000/100Mbps PCI Express Gigabit Ethernet NIC Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket - Image 3](https://m.media-amazon.com/images/I/611Qa7xjO5L.jpg) ![PCIe 3.1 2.5GBase-T Network Adapter with Intel I225-V / I226-V 2500/1000/100Mbps PCI Express Gigabit Ethernet NIC Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket - Image 4](https://m.media-amazon.com/images/I/618XSQeg3EL.jpg) ![PCIe 3.1 2.5GBase-T Network Adapter with Intel I225-V / I226-V 2500/1000/100Mbps PCI Express Gigabit Ethernet NIC Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket - Image 5](https://m.media-amazon.com/images/I/51RHTnYnxhL.jpg) ## Questions & Answers **Q: Will this work with Truenas Scale?

A great value for the money for the performance of this NIC. ### ⭐⭐⭐⭐ Easy to install and load drivers. *by A***A on July 1, 2023* DIED after two weeks. During its brief life it worked great. Guess I'll be spending a little extra money on something better. We had a lightning storm. I checked my computer devices to see if anything was damaged. Everything runs through an APC ups circuit protector. Everything is fine, however now the Network Adapter is working. Two weeks so far. I'll let you know if that changes. Spooky. ## Frequently Bought Together - 2.5GBase-T PCIe 3.1 Network Adapter with Intel I225-V+3ft Cat8 Ethernet Cable 2500/1000/100Mbps PCI Express Gigabit Ethernet Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket - 10Gtek SFP+ DAC Twinax Cable - 10GBASE-CU Passive Direct Attach Copper SFP Cable for Cisco SFP-H10GB-CU2M, Ubiquiti UniFi UC-DAC-SFP+, Meraki, Fortinet, D-Link, 2-Meter(6.6ft) | 0.25-12m Optional - 10Gtek 10Gb PCI-E NIC Network Card, Single SFP+ Port, with Intel 82599EN Controller, Ethernet LAN Adapter Support Windows Server/Linux/VMware, Compare to Intel X520-DA1(E10G42BTDA) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/502190384-pcie-3-1-2-5gbase-t-network-adapter-with-intel](https://www.desertcart.com.br/products/502190384-pcie-3-1-2-5gbase-t-network-adapter-with-intel) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-05-31*
