Wireless mouse movement may be slow due to several reasons:
< br >
1. Low battery: If you are using a battery powered wireless mouse, low battery may cause the mouse to move slowly or not smoothly. Try replacing the battery or charging it to make sure the mouse has an adequate power supply.

2. Interference: The performance of the wireless mouse may be interfered with by other wireless devices, such as wireless keyboards, Bluetooth devices, mobile phones, etc. Try to keep these devices at a sufficient distance from the wireless mouse to reduce interference.

3. Weak signal: If the distance between you and the computer is far away, or something blocks the signal transmission path between the wireless mouse and the receiver, the wireless mouse may be slow to respond or move slowly. Try to narrow the distance between the wireless mouse and the receiver, and make sure that no objects block the transmission of the signal.

4. Wheel dust: When the wheel dust or dirt accumulates, it may cause the mouse to move slowly. Use a can of compressed air or a small brush to clean the area around the mouse wheel to ensure that the wheel is unimpeded.

5. Driver issues: If your wireless mouse uses a specific driver or software, make sure you have the latest driver installed. Sometimes, updating or reinstalling drivers can solve the problem of slow mouse movement.

If the above methods do not work, you can try to connect the wireless mouse to another computer to determine whether the problem is related to the wireless mouse itself or the computer. If the problem occurs on multiple computers, you may want to consider replacing or repairing the wireless mouse.
