Supports PXE function Trouble shooting Tips Why can't my computer recognize the 2.5Gbps Ethernet PCIe card? 1. Check if the gold connectors of the card are clean, if not, clean the surface of the connector. 2. Make sure the PCI Express card is properly inserted into the PCI Express slot, if not, turn off the computer and plug it in again. 3. If this is still not the case, please change another PCI Express slot on your motherboard. 4. The motherboard itself could be defective. You can try another motherboard to test whether the 2.5Gbps Ethernet PCle Card works or not. Why can't I use Gigabit Ethernet transfer speeds? 1. Please confirm that your Ethernet environment supports Gigabit structure. 2. Please use CAT 6 UTP/STP cable

Review: No issues with a proxmox host. - I was just looking for a replacement for my onboard nic. 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. 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 Win10/11,Linux Kernel 5.8/5.16.18,RHEL 8.1/8.3/8.6,Ubuntu* 22.04 LTS,FreeBBSD 13.0,VMware ESXi7.0/8.0,DPDK 20.05/22.07,OPENWRT/UNRAID/PVE.Support PXE function
- 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

### ⭐⭐⭐⭐⭐ No issues with a proxmox host.

### ⭐⭐⭐⭐⭐ Works great on Opnsense FW - 2nd for unraid
*by C***S on April 15, 2025*

I installed this in my opnsense v17.1.5 firewall and it saw them right away. 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.
