A. 1. Ensure that your Wi-Fi network is stable and has a strong signal. Place the router closer to the robot if possible. 2. Restart both the robot and your iPhone. This can help reset the connection. 3. Check for any firmware updates for the robot and install them through the app. 4. If the issue persists, try resetting the robot's network settings and reconnecting it to your Wi-Fi.

B. 1. Remove any potential interference from other devices that may be using the same frequency band (2.4GHz or 5GHz). 2. Consider using a Wi-Fi extender to improve connectivity in areas where the robot operates.
