WiFi/Bluetooth Module Board
This module handles all wireless RF handshaking; intermittent disconnects occur when the module's transceiver fails to maintain a stable clock signal or suffers from thermal instability. Replacing this granular board restores the physical interface between the TV's OS and the wireless environment.

Main Logic Board (A-Board)
The main board houses the SoC and the USB controller that manages the WiFi module's data lane. If the WiFi toggle in the menu automatically flips to 'OFF', it indicates the system-on-chip can no longer detect the peripheral hardware due to a failure in the main board's PCIe/USB bus or power regulation circuit.

USB 3.0 to Gigabit Ethernet Adapter
Due to a known engineering bottleneck where the internal NIC (Network Interface Controller) shares a congested bus, an external USB adapter serves as a functional 'service kit'. It bypasses the failing internal WiFi hardware and the problematic 10/100 Ethernet port to provide a stable network path via the TV's USB 3.0 port.
