Description
The TP-Link UE306 USB 3.0 to Gigabit Ethernet Network Adapter is a compact, high-performance adapter designed to add wired Gigabit Ethernet connectivity to devices lacking an RJ45 port, such as ultrabooks, Chromebooks, laptops, desktops, and Nintendo Switch. Equipped with a USB 3.0 Type-A interface and a Gigabit Ethernet port, it supports network speeds up to 1000Mbps, delivering fast and stable connections for large file transfers, HD video streaming, online gaming, and video conferencing, offering better reliability and lower latency compared to Wi-Fi. The adapter uses the Realtek RTL8153 chipset for consistent performance and is backward compatible with USB 2.0/1.1, though speeds are limited to ~300Mbps on USB 2.0 ports.
The plug-and-play functionality ensures instant setup on Nintendo Switch, Windows 11/10/8.1, and Linux OS, with no drivers required. For Windows 7/8 and Mac OS X 10.6–10.15, drivers must be downloaded from TP-Link’s website. The foldable cable design and compact size (71 × 26 × 16.2 mm, ~20g) make it highly portable, ideal for travel or gaming setups. An LED indicator displays network status. Reviews highlight its fast speeds, ease of use, and Nintendo Switch compatibility, though some users report heat buildup after prolonged use (8–10 hours) and occasional disconnections on M1 MacBooks. A CAT6 or higher Ethernet cable is recommended for full 1Gbps speeds.
Compared to the UE300, the UE306 is a newer model with enhanced Nintendo Switch support but similar core specs. Unlike the UE300C (USB-C version), it’s designed for USB-A devices. Compared to the UH7020C (7-in-1 hub), it focuses solely on Ethernet connectivity without additional ports like HDMI or USB hubs. It’s ideal for adding wired connectivity or replacing broken Ethernet ports on USB-A devices.
