Why Your Raspberry Pi's Wi-Fi Keeps Dropping

Your Raspberry Pi's built-in Wi-Fi isn't badly designed — in an anechoic chamber it measures above -2 dB, roughly 70% efficiency. So why does the link fall apart in the real world? This episode digs into the physics and field data behind unstable SBC connectivity: PCB trace antennas that are narrowband and placement-sensitive, USB 3.0 broadband noise that can raise the 2.4 GHz noise floor by up to 25 dB, and why the adapter you should buy is the best-supported one, not the fastest. We also cover what "high gain antenna" claims actually mean, why chipset choice has narrowed to three suppliers, and how USB bus power budgets cause drops that look exactly like Wi-Fi problems.
