Step by step

    Replicate previous network settings

    Before updating individual devices, configure your new router to match the previous Wi-Fi network's SSID and password exactly. This forces most devices to reconnect automatically without requiring manual intervention.

    Note: Ensure you are using the same security protocol, such as WPA3 or WPA2-AES.

    Update smart hubs first

    If you changed your network credentials, prioritize updating your main smart hubs like Apple HomePod, Philips Hue Bridge, or Amazon Echo. Open the respective bridge application, navigate to Settings, and select Network or Wi-Fi to update the connection credentials.

    Power cycle non-responsive devices

    For devices that fail to reconnect after 60 seconds, perform a hard power cycle. Unplug the device from the wall outlet, wait 30 seconds, and reconnect power to force a re-handshake with the new router.

    Note: Check the status light patterns to identify if the device is searching for the network.

    Force pairing mode on peripherals

    If a device remains offline, open its specific companion app and select 'Add Device' or 'Replace Wi-Fi.' Follow the on-screen instructions to trigger pairing mode, which typically involves holding a physical reset button for 5 to 10 seconds until a status LED flashes.

    Note: Do not delete the device from your smart home app unless absolutely necessary.

    Update static IP reservations

    If you use static IP addresses for specific devices like security cameras or NAS drives, log in to your router's DHCP reservation list. Update the hardware MAC addresses to match the static IPs to ensure stable connectivity.

    Note: Access your router admin page via 192.168.1.1 or 192.168.0.1.

    Refresh HomeKit or Matter ecosystem

    Open the Home app on your primary controller device. If any accessories show 'No Response,' tap the accessory tile, navigate to Settings, and check if the device reports a connection error. A simple system reboot of the controller hub will often finalize the mesh reconnection.

    Note: Avoid resetting the entire Home database unless you have no other recourse.
