You installed a new wireless mouse on every computer in the Sales department. You check if every mouse is working correctly and notice that at one of the computers, the pointer is jumping across the screen instead of moving smoothly. What should you do first?
  1. Check if the receiver station is too far from the mouse.
  2. Reboot the computer.
  3. Connect the receiver station to another port on the computer.
  4. Reinstall the drivers.
Explanation
Answer: A - You need to check if the receiver is too far away from the mouse. This may cause signal loss and the mouse may not be able to communicate with the transceiver.

Key Takeaway: In case you are on the boundary of signal reception, the mouse pointer may behave erratically due to lower signal strength of the signals sent to the receiver. Get the mouse closer to the receiver.
