SONY TV A80K OLED WIFI WON T CONNECT General Troubleshooting

Wi-Fi/Bluetooth Transceiver Module

This internal component handles all wireless handshaking. Research suggests the SoC/connections in the A80K are 'showing signs of age' and instability; replacing the physical module resolves hardware-level connection failures where the SSID is not found or fails to authenticate.

USB 3.0 to Gigabit Ethernet Adapter

Statistically, this is the most reliable 'field fix' mentioned in owner discussions (Source 1). It bypasses the problematic internal Wi-Fi and 100Mbps Ethernet controller entirely, utilizing the TV's USB 3.0 bus to provide a stable network connection without opening the chassis.

Main Board (A-Board)

The network interface controller (NIC) and PCIe lanes for the Wi-Fi module are integrated into the main system-on-chip (SoC). If a cold reboot and module replacement fail, the failure is likely a trace-level defect or SoC degradation on the main logic board.
