USB 3.0 Gigabit Ethernet Adapter

The Tripp Lite U336-000-R adds a wired 10/100/1000 Mbps network port to any computer with a free USB 3.0 Type-A socket. It targets users whose laptops or desktops lack built-in Ethernet or need a replacement for a failed onboard controller. The compact black dongle draws power directly from the bus and requires no external supply.

IEEE 802.3az and checksum offload support

Compliance with IEEE 802.3az Energy Efficient Ethernet lets the link enter low-power idle periods when traffic drops, reducing host-system load. IPv4 and IPv6 checksum offload engines move packet validation into the adapter hardware, freeing CPU cycles for other tasks. These features change the adapter from a simple physical-layer bridge into a modest acceleration device.

USB 3.0 bus and 1 Gbps PHY ceiling

The USB 3.0 SuperSpeed interface caps practical throughput at the bus signalling rate, while the Ethernet PHY is limited to 1000 Mbps full-duplex. Real-world speeds will sit below the theoretical maximum due to protocol overhead and host-controller scheduling. Buyers needing multi-gigabit or 10 GbE performance must select a different interface class.

Questions about this item

Does the USB 3.0 male connector on the U336-000-R wear out after repeated insertion cycles?

The adapter uses a single USB 3.0 male plug rated for standard insertion durability; no moving parts or replaceable contacts exist on the unit.

What thermal limit appears first when the adapter runs at 1000 Mbps continuously?

The aluminium housing dissipates heat passively; sustained gigabit throughput stays within the IEEE 802.3az Energy Efficient Ethernet envelope without active cooling.

How much extra power does the U336-000-R draw from the host USB port during all-day operation?

It draws bus power only, compliant with USB 3.0 SuperSpeed limits, and the 802.3az feature reduces draw during low-traffic periods.
