Main Logic Board Assembly
The Sonos Sub (Gen 3) relies on a dedicated 5GHz radio module to establish a low-latency peering bond with a primary speaker. A failure to connect, especially when prompted for a PIN, indicates a logic failure in the device's ability to negotiate a secure handshake or resolve an IP address via the primary speaker's bridge. Replacing the main logic board resolves potential hardware-level radio degradation and clears corrupted internal firmware states that prevent network discovery and authentication.
