2.5G PCIe LAN Adapter with Intel I226

This network interface card adds a 2.5 gigabit RJ45 port to a desktop PC through any PCI Express x1, x4, x8 or x16 slot. It is intended for users who need wired throughput beyond standard gigabit but do not require 10G infrastructure. The Intel I226 controller handles 100M, 1000M and 2500M speeds with full-duplex flow control and Energy Efficient Ethernet support.

Check slot type and OS version before ordering

The card fits any PCIe slot from x1 to x16, so verify that a free slot is physically accessible on the motherboard. Driver support is provided for Windows 10 and Linux kernels 4.20, 5.x or later, CentOS/RGEL 8.1 or later, and Ubuntu 14.x, 15.x, 16.x or later. Systems running older kernels or unsupported Windows releases will not recognise the adapter without manual driver work.

Low-profile bracket included for small-form-factor

A 12cm standard bracket and an 8cm low-profile bracket are supplied, letting the card fit full-height and compact chassis alike. The single RJ45 port connects to existing Cat5e or better cabling, freeing the motherboard's onboard gigabit port for a separate network segment or failover. Buyers needing multiple 2.5G ports, fibre uplinks or Wi-Fi capability should look at multi-port or combo cards instead.

Questions about this item

Does the card include both mounting brackets or do I need to buy the low-profile one separately?

The adapter ships with a 12cm standard bracket and an 8cm low-profile bracket so it fits full-height and small-form-factor PCs without extra parts.

Should I choose the 100M, 1000M or 2500M setting for my network?

The card auto-negotiates; it will run at 2500M on a 2.5GBASE-T switch, drop to 1000M on Gigabit gear, and fall back to 100M on older 100M links.

What does the 2.5Gbps rating mean when the card is installed in a PCIe x1 slot?

A PCIe x1 Gen 3 link provides roughly 8Gbps bandwidth, so the 2.5Gbps Ethernet throughput is not limited by the slot.
