2.5 Gigabit Ethernet PCI Express PCI-E Network Interface Card 10/100/1000/25000 Mbps RJ45 LAN Intel I225 Chipset

The additional speed and compatibility with my ThinkCentre were very welcome, all file transfers etc have the hoped for boost. It seems to take 5-10 seconds to wake up and reconnect to the network after a sleep mode/ standby period with the PC, but that's long enough to make sure your tea is properly stirred.

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.

Works well for what I needed it for

This is working great in Unraid. Showed up as an interface as soon as I installed it. I have 1.5Gbps internet service and speed test is showing 1.6Gbps from Unraid server. Price was great for an Intel card and was shipped in 1 day.

当時のFreeBSDのバグで2022/09時点で最新のXigmaNASではI225-Vが動作しないようです。 dmesgではI225-Vとして認識されているようでしたが、次の行で 『Setup of Shared code failed, error -2』と出ていました。 現状最新版のFreeBSDでは改善されているようですが、XigmaNASの対応後に追記したいと思います。

I installed this in my old QNAP TS-563 expansion slot. I had to change to the low profile header, and then bend the header flat because QNAP decided to use a flat header. I will duct tape the header to the chassis. But the good news is that it works at 2.5G. Price of this was $17 and change, the QNAP one is $70. I will deal with the duct tape. Edit 6 months later - still working great
