WisdPi Launches the First USB-C Network Adapter with Realtek RTL8157 5Gbps Ethernet Chip
The widespread adoption of 4K video streaming, online gaming, cloud computing, and big data applications has driven growing demand among consumers and enterprises for higher-speed, lower-latency network connections. While 1Gbps and 2.5Gbps Ethernet ports remain mainstream today, attention is shifting toward even higher-speed solutions, particularly in scenarios requiring high-performance computing, HD video editing, and large-scale data transfers.
Historically, 5Gbps and 10Gbps network adapters have predominantly relied on PCIe interfaces, making them suitable primarily for desktops and high-performance workstations. However, lightweight laptops, tablets, and other devices without PCIe interface support have been underserved by this market segment.
Recently, ChargerLAB learned that WisdPi has launched a 5Gbps USB-C network adapter featuring the debut of Realtek’s RTL8157 chip. Here is a closer look at this innovative Ethernet controller.
The RTL8157 is a high-performance USB 3.2-to-5Gbps Ethernet controller chip developed by Realtek. It supports Ethernet speeds ranging from 100Mbps, 1Gbps, 2.5Gbps, to 5Gbps and is compatible with USB 3.2 while maintaining backward compatibility with previous USB standards. This makes it an ideal solution for USB-to-Ethernet adapters, embedded systems, and other networked devices.
The Realtek RTL8157 is among the world's first commercially available USB-based 5Gbps network chips. With its innovative design, the chip allows Ethernet connectivity to be extended to devices without traditional Ethernet interfaces. This includes ultra-thin laptops and tablets that lack 2.5G or higher network ports.
One of the standout features of the RTL8157 is its low power consumption, which strikes a balance between performance and energy efficiency. Compared to more power-hungry 10Gbps Ethernet solutions, the RTL8157 generates less heat while maintaining robust performance. During rigorous testing, the chip's maximum temperature under high workloads was recorded at just 38°C, showcasing its excellent thermal management and stable operation.
The RTL8157 is compatible with major operating systems, including Windows, macOS, and Linux. However, for Windows systems, only Windows 11 currently offers seamless plug-and-play functionality. Older Windows versions, such as Windows 10 and below, may face compatibility issues, awaiting future driver updates from Realtek. On Linux, additional driver installations or kernel adjustments may be required for optimal performance.
The launch of the WisdPi USB-C network adapter equipped with the Realtek RTL8157 chip addresses the growing demand for high-speed, portable Ethernet solutions. With its advanced technology, energy efficiency, and broad application scenarios, the RTL8157 chip is poised to set a new benchmark for USB-based network adapters in the 5Gbps market.
