Avoid placing the receiver near metal objects or other wireless devices (e.g., Wi-Fi routers).
If using a USB extension cable, move the receiver closer to the mouse.
Fix 4: Re-pair the Mouse and Receiver
The G602 communicates via a dedicated receiver. If pairing has failed:

Right-click each USB Root Hub entry and choose "Properties".
Go to the Power Management tab and uncheck "Allow the computer to turn off this device to save power".
Apply the changes and restart the computer.
Fix 6: Reinstall Logitech Gaming Software or G HUB
Sometimes, configuration errors in Logitech software can cause connection issues:
Open Control Panel, go to Programs and Features, and uninstall Logitech Gaming Software.
