TeKit USB 3.0 Gigabit Ethernet Adapter

This TeKit adapter adds a wired RJ45 network port to devices that lack one, such as ultrabooks, tablets or a Nintendo Switch. It connects through a USB 3.0 Type-A plug and draws power directly from the bus, so no external supply is needed. The compact dongle suits home office users, travelers and gamers who prefer a stable cable link over Wi-Fi.

10/100/1000 Mbps over USB 3.0 5 Gbps bus

The adapter negotiates at 10, 100 or 1000 Mbps and runs on the USB 3.0 5 Gbps channel, with fallback to USB 2.0 and 1.1 ports. Link and Activity LEDs show connection status at a glance. It complies with IEEE 802.3, 802.3u, 802.3ab and 802.3az Energy Efficient Ethernet standards for broad switch compatibility.

Works with Windows, macOS, Linux and Chrome OS

Supported systems include Windows 8.1, 8, 7, Vista and XP, macOS 10.6 through 10.12, Linux kernel 2.6 and 3.x, and Chrome OS. Windows RT and Android are not supported. The adapter frees up a damaged onboard port or provides Ethernet where none exists, leaving other USB sockets free for peripherals.

Questions about this item

What does the 1000 Mbps rating mean once the adapter is plugged into a USB 3.0 port?

The adapter delivers full gigabit ethernet speeds of 10/100/1000 Mbps over the USB 3.0 5 Gbps bus, giving a wired connection that is faster and more reliable than most wireless links.

Which USB standard does the adapter use and what speed does that cap the connection at?

It uses a USB 3.0 male A connector with a 5 Gbps bus, backward compatible with USB 2.0 and 1.1, so the ethernet link is limited by the USB 3.0 bandwidth.

What physical ports and connectors are needed to fit this adapter?

A free USB 3.0 Type-A port on the host device and a standard RJ45 ethernet cable are all that is required; the adapter is USB powered with no external supply needed.
