Check the supplied C-type power adapter, placement distance, and LED colour
- Who:
- TV owner inspecting the external Wireless One Connect box.
- How:
- Confirm the box is plugged into a wall outlet using only the supplied dedicated C-type adapter and cable, keep it in the same room within 10 metres outside closed cabinets and away from metal or concrete walls, and select Adjust on the TV while repositioning the box until the LED turns blue.
- Result that matters:
- The LED indicator changes from red or yellow to solid blue (good signal) and Low Signal Check or Power Adapter Check alerts clear.
- If the LED stays solid blue and picture returns:
- the disconnection was caused by placement or power supply.
- If the TV still reports Wireless One Connect is disconnected:
- run the built-in Self Diagnosis test.
- Evidence to keep:
- Photo of the LED indicator colour on the Wireless One Connect box and its placement relative to the TV.

What it means
On Samsung's official Wireless One Connect support guide (covering compatible models such as QN990FW and LS03FW; other models and regions may differ), the Wireless One Connect is disconnected message appears when the box loses power, experiences weak signal, or becomes unpaired, and Self Diagnosis reports Case 1 (Wi-Fi is not detected), Case 2 (Wireless One Connect is not detected), or Case 3 (not paired with the TV). This message alone never proves a hardware part is faulty.
