Say, the Microsoft Wireless Mouse AND Keyboard has a wireless dongle. This has gone missing. What items can we purchase to replace it? Is it economical to buy a dongle? We based in South Africa. Kindly suggest something decent that will be easy to configure with it.
Each wireless dongle and mouse/keyboard set are "matched" to the radio frequency that they've been configured to use, this is set at the factory.
No two wireless sets have the same frequency to avoid "crossover" when two sets are being used in close proximity (college PC classes, family members at home, etc).
You'll have to buy a new wireless set complete with matching transceiver.
I suggest that you seriously consider a Bluetooth keyboard/mouse system.
