Question
A user reports that their wireless mouse lags intermittently. The mouse uses a USB receiver, and other USB devices work fine. What should the technician try first?
A. Replace the mouse batteries
B. Update the mouse driver
C. Change the USB port
D. Adjust the mouse polling rate
E. Re-pair the mouse with the receiver
Answer
E. Re-pair the mouse with the receiver
Explanation
Intermittent lagging in a wireless mouse is often due to a disrupted connection between the mouse and its USB receiver. Re-pairing the mouse can restore a stable connection.
Intermittent lag in a wireless mouse that uses a USB receiver, while other USB devices function normally, is frequently due to a disrupted or unstable connection between the mouse and its receiver. Re-pairing the mouse with the receiver re-establishes a clean, stable communication channel, which often resolves lag and connectivity issues.
This step is non-invasive and addresses the most common cause of wireless mouse lag not related to hardware faults or battery issues. If re-pairing does not resolve the problem, further troubleshooting can include checking for interference, relocating the receiver, or updating drivers, but re-pairing is the recommended initial action for this scenario.
