If both 2.4GHz and 5GHz are available at your home Wi-Fi, please refer to the suggestions below:

If Pixsee Play is placed in a smaller area where the router is relatively close with your camera with no walls in between, then 5 GHz Wi-Fi would be a good choice. However, if you are expriencing an intermittent or unstable connection to Pixsee, then switching to 2.4 GHz Wi-Fi is recommended instead.
If Pixsee Play is placed in a larger area where the router is relatively further away with physical objects or walls in between, and Pixsee Play might need to move around for stronger signals, then 2.4 GHz Wi-Fi would provide a better connection.
Note: When resetting Wi-Fi, please make sure Pixsee Play and mobile device are connected to the same Wi-Fi.
