Quick Solutions
Still having issues? This is usually the deeper cause below.
If the device became unresponsive after a firmware update, a factory reset usually clears the corrupted state — the update itself is rarely the root cause.
Keep the controller near the center of the layout for better signal distribution.
Firmware updates that wipe settings are more common than brands admit — many devices silently reset to factory defaults on an OTA push with no warning.
