- For 2.4G connection, try moving the USB receiver to a different USB-A port on your computer.

- Ensure the mouse or receiver is connected directly to the computer, not through a hub, extender, or switch.
- Move the mouse closer to the USB receiver (for 2.4G mode). If the receiver is in a rear port, try a front port.
- Minimize interference by keeping other wireless devices (e.g., wireless speakers, monitors, cell phones) away from the USB receiver.
- Remove any other wireless adapters/receivers from your computer, except for the iClever receiver.
