What do you recommend?
We’ve had some problems with some that we have tried.
At first we got some cheep wireless units because they liked the look. These wireless units had problems staying connected to the correct computer.
I then purchased some Bluetooth units. With computers that have built in Bluetooth, that has worked well. Using Trendnet USB dongles has been problematic in that at times the Bluetooth service will not work. They also take a long time to
wake up when the computer boots up.
