Smart TV Wi-Fi troubleshooting guide
Need repair help? Wi-Fi problems can come from the router, TV settings, software, a wireless module, or the main board. Isolate the network before replacing parts. Repair Help

Confirm the Network Works First

Verify that another phone or computer can connect to the same Wi-Fi network. Restart the modem/router and the television, then try the connection again.

Forget and Reconnect to the Network

Remove the saved Wi-Fi network from the TV and reconnect using the correct password. If the TV can see nearby networks but not yours, check router band, channel, and security settings.

Test Ethernet if the TV Has a Network Port

If a wired Ethernet connection works while Wi-Fi does not, the internet service and most smart-TV software are functioning. That narrows the problem toward the wireless path, antenna, module, or main board.

Check the TV's Date, Time, and Software

Incorrect system time or outdated firmware can interfere with secure network connections on some smart TVs. Use the manufacturer's update procedure when the set can still access updates safely.

Wi-Fi Module vs. Main Board

Some TVs use a separate Wi-Fi/Bluetooth module connected by a cable, while others integrate wireless functions into the main board. If Wi-Fi and Bluetooth fail together, inspect the model's design before ordering a replacement.

Look for a Repeatable Symptom

Note whether the TV sees zero networks, connects and immediately drops, works only near the router, or fails after warming up. Those details are more useful than simply describing the TV as “offline.”
