Y-RBN90 / MRCR147R Cordless Keyboard/mouse combo, NOT WORKING.

I've had this combo for a year or so now, and I just recently got a new computer. I've reinstalled the drivers (or so I thought), and nothing still seems to work. There are no more drivers available to download. I've restarted the computer. The battery light on the keyboard is not on, though it has a fresh battery and is on. The mouse also has a fresh battery, but the light is green and slowly blinking. It's plugged in, and should be charging. But yet I still can't use either of them at all! I have no idea what to do, and after scouring the forums for help, it seems like others have had this problem, with no solution. Please help!

Hello prowler86,


When your Cordless Desktop Wave Pro isn't working, there is usually a connection issue. The connection between the combo and the USB mini-receiver can be lost for several reasons, such as:

  • Low batteries.
  • Moving the USB receiver from one port to another.
  • Moving the USB receiver to another computer.
  • Plugging the receiver into a USB hub or other unsupported device such as a KVM switch (NOTE: Your receiver must be plugged directly into your computer).
  • Using your wireless keyboard/mouse on metal surfaces.
  • Radio frequency (RF) interference from other sources, such as:
    • Wireless speakers
    • Computer power supplies
    • Monitors
    • Cell phones
    • Garage door openers


If the problem persist, you can purchase a new USB mini-receiver:

I hope this information helps.

[ Edited ]

My mouse has suddenly stopped scrolling side to side. I have tried uninstall and reinstall, changed the batteries, moved the USB to a new port, placed the cell phone further away (though I have always kept the cell and the mouse together on my desk)

Any assistance would be appreciated. {Personal content removed}

thank you
