APPLE MAC MINI M2 Wifi Dropping

Logic Board

The Wi-Fi and Bluetooth radio controller is an integrated component of the M2 System-on-Chip (SoC) on the logic board. Persistent packet loss and the inability to maintain a handshake with 5GHz frequencies—while other devices on the same network remain stable—point to a failure in the radio's PHY/MAC layer or the integrated power management of the wireless module.

Internal Wi-Fi Antenna Assembly

This model utilizes a specialized internal antenna plate situated near the bottom cover. If the U.FL micro-coaxial connectors have vibrated loose or if the antenna's dielectric material is compromised, the signal-to-noise ratio (SNR) drops significantly, causing the macOS networking stack to drop the connection in favor of a stronger (but potentially unreachable) band.

USB-C Shielded Data Cable

The Mac Mini chassis design is highly susceptible to Radio Frequency Interference (RFI) from unshielded USB 3.0/USB-C peripherals. These devices emit noise on the 2.4GHz spectrum that matches the Wi-Fi/Bluetooth resonant frequency, effectively 'drowning out' the router's signal and causing the dropping behavior.
