Wireless Keyboard and Mice: More Troubleshooting Steps
Another common problem is that the receiver for the wireless keyboard or mouse can be too far away for them to work. I have personally seen cases where the mouse works if used on one side of the mouse pad, and not the other. This was due to the distance of the mouse from the receiver being too great when on the far side of the mouse pad. The same can be true of a keyboard. This will also cause the same jerky motions to a mouse, and missed keys on a keyboard.
The solution to this problem is to move the receiver closer to the keyboard and mouse. If the receiver is of the USB fob type (similar in shape to a USB memory stick) then you can buy a USB extension cable and place the fob closer. Perhaps placing it next to the monitor would work best. If the receiver has a tendency to fall behind your desk, a small, clear piece of scotch tape will hold it down, and will be one hundred percent removable if you decide to move it later.
If your wireless keyboard or mouse have a desktop receiver, try moving it a little closer.
You may also need to press the "connect" buttons on the receiver and also underneath the keyboard and mouse. If they have an on/off switch you should turn them on and off.
