## Overview

The USB 4.0 Type-C 10G Ethernet Adapter by IO CREST delivers ultra-high-speed 10Gb/s network connectivity via USB-C or Thunderbolt 3/4/5 ports.

## Description

This network adapter offers a portable, bus powered, fanless and low-cost 10GbE solution enabling 10GBase-T and NBASE-T (IEEE 802.3bz-2016) connectivity for Apple® OS X® and Microsoft® Windows® environments over USB4.0. It is compatible with Thunderbolt 3/4/5. Ideal for notebooks like the MacBook Pro (late 2016) and professional workstations that require reliable, accelerated access to external storage and networks for I/O demanding applications.

Review: Gets HOT, but pulls data at 10GbE. Requires Thunderbolt, not just USB 4! - Have not used it for extended periods of time, but seems to work correctly when combined with a USB4 or Thunderbolt4 port. It does get HOT, so don't put anything on top of it. Windows 11 driver worked just fine out of the box, but I did tweak some settings. I do this on all my Ethernet adapters. If your USB4 port is not also Thunderbolt, this device will not show up as a network adapter. It uses the Aquantia chip. It will show up as a USB device with no function.
Review: 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.

### ⭐ Linux/Fast/Stable
*by D***N on July 28, 2025*

Linux plug and play. Works great on 6x kernels. 600MB/s to and from my TruNAS machine running four Hitachi 10TB platter drives in zraid. Performance is steady and stable. EDIT Nov.25 Updated to 1 star. Less if I could. I've had two of these burn out this year and had to return them. Still recognized as present but fail to connect or get an IP. Real pain too because I have to remove my 4090 bracket to remove the card. Truly happy this works because it's the only x1 card I could find. Most of my board is blocked off by my RTX4090 and brace. Only other exposed slot is x8 but it has a card with 4x m.2 nvme drives on it. EDIT 8/16/2025 The card lasted less than three weeks and died. Does not recognize that a cable is even plugged in. I bought two and the second is working in place of the failed nic. We will see how long that lasts.
