USB 3.0 Gigabit Ethernet with 3-Port Hub
This adapter adds a gigabit RJ45 port and three USB 3.0 ports through a single USB 3.0 connection. It is aimed at users whose laptop or desktop lacks a wired network jack or needs extra peripheral ports. The aluminium body helps dissipate heat during extended use. No driver installation is required on Windows 8, 8.1, 10, macOS 10.9 and newer, or supported Android and Linux devices.
Sustained throughput on the USB 3.0 link
The USB 3.0 input is rated at up to 5 Gbps, which caps the combined bandwidth available to the Ethernet port and the three downstream USB ports. Under continuous heavy traffic the gigabit Ethernet connection will share this pool with any active USB devices, so aggregate throughput cannot exceed the host link. The aluminium casing provides passive cooling to maintain stable operation during long transfers.
Practical limits of the USB 3.0
The RJ45 port follows IEEE 802.3, 802.3u and 802.3ab, delivering 10, 100 or 1000 Mbps Ethernet with auto-negotiation and pause-frame support. The three USB 3.0 ports are backward compatible with USB 2.0, 1.2 and 1.0 devices. On Windows 2003 through Windows 7 and macOS versions below 10.9 a virtual CD-ROM step is needed before the adapter becomes driver-free.

Questions about this item
Does the aluminum-alloy casing keep the adapter cool when the Gigabit RJ45 port and all three USB 3.0 hub ports run continuously?
The supplier describes a mini-sized aluminum alloy housing for heat dissipation, but no thermal ratings or power-draw figures are provided.
Must the host computer have a USB 3.0 Type-A port, or will a USB 2.0 port work for the Gigabit Ethernet and hub functions?
The adapter plugs into a USB 3.0 interface for up to 5 Gbps throughput; the three downstream USB ports are backward compatible with USB 2.0, 1.2 and 1.0 devices.
Will the Gigabit RJ45 port negotiate 1000 Mbps on an older Cat 5 cable, or does it require Cat 5e or better?
The RJ45 interface follows IEEE 802.3, 802.3u and 802.3ab standards and is downward compatible with 100 M network cables.
