USB 3.0 hub and Gigabit Ethernet in one

The Tripp Lite U336-U03-GB adds a Gigabit Ethernet port and three USB 3.0 ports through a single SuperSpeed connection. It is designed for laptops or desktops that lack a wired network jack or need extra USB ports. The compact black adapter weighs 0.7 units and works with USB 2.0 and 1.1 devices at their native speeds.

Sustained throughput on the Ethernet port

The Gigabit Ethernet port delivers true 10/100/1000 Mbps network speeds for consistent wired connectivity. All three USB ports support data transfer rates up to 5Gbps when connected to a USB 3.0 host. Under continuous load the hub maintains SuperSpeed bandwidth across all ports without throttling back to legacy rates.

Practical limits of the USB 3.0 interface

The adapter is backward compatible with USB 2.0 and 1.1 devices, though they operate at USB 2.0 and 1.1 speeds respectively. Total bandwidth is shared across the three USB ports and the Ethernet controller on the single upstream link. Buyers who need more than three downstream ports or a separate dedicated Ethernet controller should consider a different solution.

Questions about this item

Does the adapter run hot or draw much power when the Gigabit Ethernet port and all three USB 3.0 ports are active all day?

The unit combines a Gigabit Ethernet NIC with a 3-port USB 3.0 hub in a compact 0.7 kg housing and draws power from a single USB 3.0 SuperSpeed connection; no external supply is needed.

What must my computer already have for this adapter to work?

An available USB Type-A port running USB 3.0 SuperSpeed; the adapter is backward compatible with USB 2.0 and 1.1 hosts at their native speeds.

Will my older USB 2.0 flash drives and 10/100 Ethernet cables work properly through this hub?

Yes — all three USB ports support USB 2.0 and 1.1 devices at their rated speeds, and the Gigabit Ethernet port negotiates 10, 100 or 1000 Mbps automatically.
