Some common problems with wireless keyboards are battery life issues, synchronization issues, interference, software problems such as device drivers, and security. Battery life is the most common complaint, but many keyboards are now being manufactured as rechargeable with a USB cable.
Wireless keyboards have a battery life that lasts roughly five to six months. One sign that the batteries may be low is erratic behavior from the device.
Synchronization issues come up when the keyboard and the USB receiver plugged into the computer get out of sync. To fix this issue, press the "Connect" button on the receiver, then the "Connect" button on the device. If the device does not have a "Connect" button, it has software that allows the user to reconnect the device to receiver.
Interference issues are common problems of Bluetooth keyboards. Microwave ovens, cordless phones and baby monitors can interfere with the keyboard's signal. If these items must be next to the computer, it may be better to use a 27 megahertz wireless keyboard.
Update all the device drivers if using Windows, and make sure the device's software is up-to-date. Finally, if data security is an issue, a regular 27 megahertz wireless keyboard may not provide enough security. Bluetooth keyboards provide more secure data encryption.
