Framework's 10G Ethernet module exposes USB-C's complexity

This article reviews the WisdPi 10G Ethernet Expansion Card for Framework computers, focusing on performance and thermal challenges. It explains how USB-C bandwidth complexity, especially with the Realtek RTL8159 controller requiring USB 3.2 Gen 2x2, limits real-world speeds to under 10 Gbps on many Framework laptops. Testing on Windows and Linux reveals varying results, with Linux driver issues and overheating reaching nearly 70°C. The article provides technical insights into USB-C standards, driver compatibility, and safety concerns, making it relevant for IT/tech enthusiasts interested in hardware performance and networking.
