- Framework's new 10G Ethernet Expansion Card uses USB-C, which complicates achieving full 10 Gbps speeds due to bandwidth limitations and compatibility with Realtek RTL8159 controller.
- Performance varies: On some Framework laptops with USB 3.2 Gen 2x2, real-world speeds reach up to 9.4 Gbps on Windows with Realtek drivers, but Linux often shows lower performance.
- The module generates significant heat, with surface temperatures nearing 70°C, raising concerns for lap use despite meeting safety standards if contact is brief.
- Recommended for non-lap scenarios; for most users, the cheaper 2.5 Gbps Ethernet card is sufficient, with the 10G card advised only for specific high-speed needs without external dongles.
