A peripheral or feature that disconnects and reconnects on a computer is usually a power-management or driver-timeout setting, not failing hardware. For Apple Handoff and Continuity, first confirm both devices use the same account with Bluetooth/Wi-Fi/Handoff enabled.
What this covers
- Apple Handoff and Continuity with this exact failure state
- Diagnosis across Apple Account and feature eligibility versus Bluetooth, Wi-Fi and app support

ReversibleNote whether the drop correlates with sleep/wake, a specific USB hub, or sustained heavy use. Expected behavior: advertise eligible activity between nearby devices on the same account.
Isolate the component boundary
ReversibleConfirm both devices use the same account with Bluetooth/Wi-Fi/Handoff enabled. Test the device on a direct port with no hub, and disable USB selective suspend for that port. Boundary to separate: Apple Account and feature eligibility versus Bluetooth, Wi-Fi and app support.
Correct only the proven cause
ReversibleUpdate, sign into the correct account or restart the one failed service. Disable the power-management setting that turns the device off to save power, or update the controller driver.
Verify and stop safely
ReversibleRun the device under the same load that triggered the drop for at least 30 minutes. Do not sign out of the account without synced data and credentials.
