USB 3.0 Gigabit Ethernet Adapter

The TeKit 20256 adds a wired network port to laptops, tablets or ultrabooks that lack one. It connects via a USB 3.0 male Type-A plug to an RJ45 female jack, supporting 10, 100 and 1000 Mbps Ethernet speeds. The short 0.5 ft cable keeps the setup tidy for desk or travel use. It is suited for users who need a stable wired link for file transfers, video calls or streaming.

Thermals, noise and power

The adapter draws power directly from the USB port with no external supply needed. It runs silently because it has no fan or moving parts. The aluminium casing helps dissipate the small amount of heat generated during sustained gigabit throughput. Energy Efficient Ethernet (IEEE 802.3 az) reduces power draw when the link is idle or lightly loaded.

Build integration

The white 0.5 ft dongle plugs into any USB 3.0, 2.0 or 1.1 Type-A socket and works with Windows 8.1 down to XP, Mac OS X 10.6 through 10.10, Linux kernel 2.6 or 3.x and Chrome OS. It does not support Windows RT or Android. Link and activity LEDs on the RJ45 face show connection status at a glance. The shielded cable resists interference in busy environments. Buyers who need a longer reach or a USB-C connection will need a different solution.

Questions about this item

How do I install the USB 3.0 to RJ45 adapter and what step do users often miss?

Plug the USB 3.0 male A connector into your computer and the RJ45 cable into the female port; the step often missed is ensuring the host USB port is actually USB 3.0, not USB 2.0, to reach 1000Mbps throughput.

What maintenance or replacement will this adapter need over time?

No scheduled maintenance is required; if the USB connector or RJ45 port wears out after repeated insertions, replace the entire 0.5 ft adapter unit.

What limit appears first during sustained high-throughput use?

The USB 3.0 5Gbps bus caps real-world throughput below the 1000Mbps Ethernet ceiling, so sustained transfers hit the bus limit before the network limit.
