My wireless keyboard / mouse doesn't have enough range, what can I do?

Tried many different wireless keyboard / mouse combos. Their advertised range is often huge, but even at half that distance performance is quite poor. Is there any way to improve it?

Solution 1:

Couple things I can think of...

Get both the mouse/keyboard & the antenna as far away from anything electrical as possible, TV, fridge, microwave,computer itself & ensure direct line-of-sight from antenna to keyboard/mouse.
Make sure everything has fresh batteries.
Maybe try a USB Extender cable to get the antenna nearer. Like this one - http://www.maplin.co.uk/p/nikkai-pure-connectivity-usb-20-a-male-to-a-female-5m-l11bt [example only, there are many types available]
