FAQ
What operating systems does this USB-C Ethernet adapter support?
This adapter offers native compatibility with Windows 7, 8, 10, 11, and Server editions; macOS versions 10.14 through 13.0; Linux distributions with kernel 4.11 to 5.9.16 LTS; and Chrome OS. In most cases, no additional driver installation is required as the ASIX AX88179A chipset is recognized automatically by these operating systems.
Does this adapter require external power or is it bus-powered?
The adapter is completely bus-powered through the USB-C connection, drawing power directly from the host device. This eliminates the need for an external power adapter, reducing cable clutter and simplifying deployment. The design supports Energy Efficient Ethernet (EEE) to minimize power consumption during periods of low network activity.
What is the maximum network speed this adapter can achieve?
This adapter supports Gigabit Ethernet speeds up to 1000 Mbps (1 Gbps) on compatible networks. The USB 3.2 Gen 1 interface provides a 5 Gbit/s data transfer rate between the adapter and host device, ensuring the Ethernet connection is not bottlenecked by the USB interface. The adapter auto-negotiates between 10, 100, and 1000 Mbps based on network infrastructure capabilities.
Can this adapter be used with devices that only have USB 3.0 or USB 2.0 ports?
Yes, the USB-C connector is compatible with USB 3.0 and USB 2.0 standards when used with appropriate adapters or cables. However, when connected to USB 2.0 ports, maximum network speeds will be limited by the USB 2.0 bandwidth (480 Mbps), which may restrict Gigabit Ethernet performance. For full Gigabit capability, connection to USB 3.0 or later ports is recommended.
What advanced networking features does this adapter support?
Beyond basic Ethernet connectivity, this adapter supports several enterprise networking features including Wake-on-LAN for remote system activation, VLAN Tagging (802.1Q) for network segmentation, 9K Jumbo Frames for improved data throughput on supported networks, and Energy Efficient Ethernet to reduce power consumption. These features make it suitable for both basic connectivity and more demanding network environments.
