How to increase the range of the wireless keyboard / mouse?

Hi,
There is a set of Keyboard and mouse, Microsoft Wireless Laser Desktop 6000 v2.0, the receiver is connected to USB, very bad works, has heard that many are and can be refined - to make the dish.

If anyone has did, let me know?

Try with Logitech wireless kit Pro 2400 Cordless Desktop OEM, works even through the concrete wall, it looks nice, works better and, most importantly, much cheaper.

Check to see whether your wireless keyboard uses radio signals or infrared signals. Increasing the range is much easier if it uses radio signals, since this allows for the use of an antenna. If your keyboard does not operate by radio signals, you can always try to improve its range by making adjustments to where you place the keyboard and the receiver. For example, try placing the receiving unit on a high shelf.
