  • Restart your computer.
• Lag or Intermittent Connection:
  • Move the keyboard and mouse closer to the USB receiver.
  • Ensure there are no large metal objects or other wireless devices (like Wi-Fi routers, cordless phones) operating too close to the receiver, as these can cause interference.

  • For the mouse, ensure the optical sensor on the underside is clean and unobstructed.
  • Ensure the keyboard keycaps are properly seated.
