This upgrade to 2.5gig Ethernet is easy to install into a PCIe slot and drivers are included on the
supplied mini CD. Many drivers are included including Windows 11, 10, Mac and Linux. Full speed
is achieved using Cat 6 wire. Both full form and small form factor hardware included - easy to change out.
Ethernet socket has two LED indicators for link and speed which is good since other cards may not have
these indicators or have holes to see through to an LED on the inside surface of the card. The Realtek chip
and the software may be able to go to 10gig in the future since there is some references in drivers and
other information of the system. Maybe a firmware update in the future for this?
Overall, this is a great product and very reasonable in price and support.

Is revision 03, but be wary of Linux/BSD use
Edit: as of XigmaNAS 13.1.0.5.9725 this adapter is now recognized and works as-expected! Thanks to ms49434 and zoon01 for applying a kernel patch to accept the PHY that is present. Original review follows.The adapter arrived in a small, cardboard box. The heatsink is attached securely. A hardware check indicates that the chip is revision 03.Under Windows 10/11, the adapter is usable with no additional effort or configuration on the user's side.Under Linux/FreeBSD, the adapter may or may not work depending on the version of the driver used to attempt init. Under FreeBSD specifically, support for the I225 was added in 13.1 via 𝚒𝚐𝚌, however the driver performs an unnecessary PHY vendor ID check, which may fail if the adapter reports an ID that isn't listed in an internal table.The fix (recommended by Intel themselves) is to no longer perform this check and instead assume a PHY for all I225 adapters. This fix is available in FreeBSD 13.2 and/or 14, and would need to be backported if using anything earlier.Examples; TrueNAS Scale 22.12.0 supports this adapter, while XigmaNAS 13.1.0.5.9687 (latest as of this review) includes 𝚒𝚐𝚌, but fails to init with the adapter I received.
