Intermittent keyboard non-functioning
I use a wireless mouse and keyboard. Every now and then, often enough to be irritating, the keyboard fails to function: the mouse works properly. The keyboard problem persists for a few minutes, after which it works again. There is no discernable pattern to this problem.
This is the third wireless keyboard to show the same problem, suggesting something is wrong elsewhere.
The keyboard batteries are not responsible for the failure.
On the same desk is a cordless telephone.
Any helpful suggestions would be very gratefully received.
