If the wireless mouse fails intermittently, you can first try to replace the battery or charge the battery to ensure sufficient power. Second, you can check whether the distance and position between the mouse and the receiver are appropriate, or try to reconnect the mouse and the receiver. If the above methods do not work, the hardware may be faulty, and the mouse needs to be replaced or repaired. At the same time, it is recommended to use a wireless mouse with a reliable brand and avoid buying cheap and low-quality products.
