Turn USB 3.0 into Gigabit Ethernet

The TP-Link UE300 adapter adds a 10/100/1000 Mbps RJ45 port to laptops and desktops that lack built-in Ethernet. It connects through a USB 3.0 Type-A socket and remains backward compatible with USB 2.0 and USB 1.1 hosts. The foldable white housing weighs 0.05 kilograms for easy travel. Driver-free installation works on Windows 11, 10, 8.1, 8, 7, Vista, XP, macOS 10.9 and later, Chrome OS and Linux.

USB 3.0 Type-A connector required

The adapter only fits a USB 3.0 Type-A port; it will not plug into USB-C, micro-USB or Lightning sockets without a separate adapter. Gigabit throughput relies on the host providing USB 3.0 bandwidth, so USB 2.0 ports limit speed to 10/100 Mbps. Nintendo Switch, Wii U and Wii are explicitly unsupported. macOS 10.6 through 10.8 need a manual driver download from the manufacturer.

Foldable design and broad OS support

The hinged body folds flat to protect the RJ45 jack and reduce bulk in a bag. Driver-free operation across current Windows, macOS, Chrome OS and Linux versions means no media or internet access is needed before the first connection. Compliance with IEEE 802.3, 802.3u, 802.3ab and 802.3az standards ensures compatibility with existing wired networks and energy-efficient Ethernet switches.

Questions about this item

How fast will file transfers actually run through the 1000 Mbps Gigabit port when the adapter is plugged into a USB 3.0 socket?

The USB 3.0 link provides enough bandwidth for the full 1000 Mbps Ethernet rate, so large-file copies and streams can sustain gigabit speed in practice.

Which Ethernet standards does the UE300 implement, and what is the highest negotiated speed?

It complies with IEEE 802.3, 802.3u and 802.3ab, enabling 10, 100 and 1000 Mbps auto-negotiation; 802.3az adds Energy Efficient Ethernet.

What physical space does the foldable UE300 need beside a laptop's USB-A port?

The folded adapter measures 2.8 by 1.0 by 0.6 inches and weighs 0.05 kg, so it clears adjacent ports on most ultrabooks and MacBooks.
