A wireless keyboard and mouse that are used on a computer system should have a range of about 5 feet but typically only work no more than 2 feet away. If you want to use your wireless keyboard or mouse from farther away, a different model may be needed. However, if you do not want to purchase new equipment, a simple modification can be made to boost or increase the wireless signal.
Connect the male end of a USB extender cable into a USB port on the computer.
Plug the receiver for the wireless keyboard or mouse into the female end of the USB extender cable.
Move the receiver unit to a different location away from the computer and monitor. Make sure there are no obstacles in the way of the receiver.
Test the keyboard or mouse and see if moving the receiver provides an increased signal or any better reception.
Secure an FM wire to the receiver for the wireless mouse or keyboard using a small piece of masking tape.
Run the excess wire up along a wall and secure it with a small piece of masking tape.
Test the reception of the keyboard or mouse to see if there is any improvement in the reception or signal.
Keep the receiver in a location so that there is a direct line of sight between it and the wireless keyboard or mouse.
Any interference from an electrical device can prevent a wireless keyboard or mouse from working at longer distances. An antenna extension will only work on a wireless keyboard or mouse that uses a radio signal.
