Step by step

  1. 1 min

    Verify Frequency Band Compatibility

    Most wearables exclusively support the 2.4GHz frequency band. Ensure your router is not broadcasting a singular 5GHz or 6GHz SSID, which will prevent the device from locating the network.

    Note: Disable 'Band Steering' in your router's wireless settings to isolate the 2.4GHz broadcast.

    Forget the Network on the Wearable

    Navigate to the Settings app on your wearable device. Select Wi-Fi, tap the name of your current network, and select 'Forget this Network' to purge stored authentication tokens.

    Reset Network Settings on the Paired Smartphone

    Your wearable derives sync credentials from your smartphone. On your phone, go to Settings > General > Transfer or Reset > Reset > Reset Network Settings to clear corrupted local sync caches.

    Note: This will remove all saved Wi-Fi passwords on your phone.

    Toggle Airplane Mode to Refresh Radio

    Swipe to the Control Center on your wearable device. Enable Airplane Mode, wait ten seconds, and disable it to force the Wi-Fi radio to re-initialize and scan for available access points.

    Re-authenticate via Companion App

    Open the companion app on your smartphone. Navigate to Device Settings > Wi-Fi and manually select your 2.4GHz network from the list of available connections. Re-enter the network password carefully to establish a new encrypted handshake.

    Note: Ensure your phone is connected to the same 2.4GHz network during this process.
