Step by step

  1. 1 min

    Disable automated smart home triggers

    Open your primary smart home application, such as Apple Home or Google Home. Navigate to the automation tab and toggle off any scheduled events or motion-based routines to prevent command execution errors during the network downtime.

    Note: This prevents devices from queuing commands that cannot be delivered during the reboot.

    Power down your router

    Locate the power cable at the rear of your router or modem/router combo. Disconnect the cable directly from the power outlet rather than using the hardware reset button to avoid factory resetting the unit.

    Note: Wait at least 30 seconds to allow the internal capacitors to discharge fully.

    Allow the network to clear

    Maintain the power-off state for at least two minutes. This ensures that the ISP connection drops and connected devices fully clear their local ARP tables.

    Note: Leaving the device off for a shorter duration may leave old IP lease information in memory.

    Restore power and establish WAN

    Plug the power cable back into the wall outlet. Wait for the router status lights to stabilize, indicating that the wide area network (WAN) connection is active and the local area network (LAN) is broadcasting.

    Note: Wait until the 'Internet' or 'WAN' light turns solid green or white.

    Verify device reconnection

    Open your smart home app and wait for the status of your devices to change from 'No Response' to 'Connected'. Most IoT devices will automatically re-handshake with the router once the 2.4GHz broadcast signal is restored.

    Note: If a device remains offline, toggle its individual power switch instead of restarting the router again.

    Re-enable automations

    Once all devices confirm an active connection in your dashboard, navigate back to your automation settings. Toggle your schedules and routines back to their original 'On' state to resume normal operation.
