So far no issues. Recognized immediately by a proxmox host. Review: Nice and fast - Has been running rock solid in a PCIe 3 slot in an old Lenovo box and has been solid and reliable for OPNsense to use without fail. The NIC worked great with the FreeBSD based router OS, so drivers were already good to go. It is very nice to have 2 NICs only taking up one slot and this leaves my x16 slot open for other uses. I was able to test a full 2.5gbe connection/link and had no trouble at all. Great value. ## 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.

No need to install any new drivers, and my FW is now upgraded from 1gb to 2.5gb - used one for the fiber modem -which to be fair is only 1gb and one to my network connected to a 2.5gb switch. ## Frequently Bought Together - Dual PCIe 3.1 2.5GBase-T Network Adapter with Intel I225-V 2500/1000/100Mbps PCI Express Gigabit Ethernet NIC Card RJ45 LAN Controller for Windows 10/11 with Low Profile Bracket - TP-Link 2.5GB PCIe Network Card (TX201) – PCIe to 2.5 Gigabit Ethernet Network Adapter, Supports Windows 11/10/8.1/8/7, Win Server 2022/2019/2016, Linux - TRENDnet 8-Port 2.5Gb Multi-Gigabit Unmanaged Gaming Switch, TEG-S380, 8 x 2.5GBASE-T Ports, 25Gbps Switching Capacity, Ethernet Splitter, NDAA & TAA Compliant, Fanless, Lifetime Protection, Black --- ## 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.it/products/624133858-st7207](https://www.desertcart.it/products/624133858-st7207) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-08*
