USB 2.0 Wired Network Adapter

The Tccmebius TCC-S20A adds a 10/100 Mbps RJ45 port to any device with a USB 2.0 socket. It is aimed at laptops, tablets, TV boxes or projectors that lack a built-in Ethernet jack or have a damaged one.

RTL8152B Chip and Plug-and-Play Design

The adapter uses an RTL8152B controller to deliver up to 100 Mbps over a wired link, avoiding Wi-Fi interference and drop-outs. Driver-free on Windows 10, 11, Android and Mac OS X 10.6 through 10.12; Windows 7, Vista, XP and Linux need a one-time driver install from the appearing folder.

Replaces Unreliable Wireless or Missing Ports

It upgrades a wireless-only or port-less device to a stable wired connection for streaming, gaming or secure file transfers. The jump is worth it when Wi-Fi is congested, the internal NIC has failed, or the hardware simply shipped without an Ethernet socket.

Questions about this item

What practical speed does the USB 2.0 interface cap this adapter at?

The USB 2.0 link limits real-world throughput to 100 Mbps even though the RTL8152B chip can handle faster Ethernet standards.

What physical port and space does the TCC-S20A need on the host device?

It plugs into any USB-A 2.0 or 3.0 socket and adds a single RJ45 jack; the dongle weighs 25 grams and is small enough to sit beside other ports.

How is the adapter installed and which step do users often miss on older systems?

On Windows 10/11, Mac OS X 10.6–10.12, Android and Chrome OS it works driver-free; on Windows XP/7/Vista and Linux a driver folder appears on the desktop and you must run its installer before the link comes up.
