Framework's 10G Ethernet module exposes USB-C's complexity
The article reviews WisdPi's new 10G Ethernet Expansion Card for Framework laptops, which uses a Realtek chip and fits any Framework expansion slot via USB-C. The author notes that while the card offers high-speed connectivity, USB-C's inherent complexity and Linux compatibility quirks present challenges.
Background
Jeff Geerling is a prominent YouTuber and blogger focused on Raspberry Pi, Linux, networking, and open-source hardware. Framework is a company that makes modular, repairable laptops (and now a desktop) whose expansion slots use USB-C internally. WisdPi is a small hardware maker that produces third-party Ethernet adapters for Framework's ecosystem. The "10G" refers to 10 Gigabit Ethernet (10 Gbps), a high-speed networking standard roughly 10× faster than typical home internet connections. The core issue: USB-C seems simple on the outside but has deeply complex signaling under the hood (different speeds, protocols, power delivery modes), and plugging a fast Ethernet chip into a USB-C port meant for general expansion can reveal performance bottlenecks, driver problems, or thermal issues that casual users don't expect.
