A very important step in setting up a smart appliance at home is its initial configuration. This usually requires the user to connect the device to a local Wi-Fi network. An important thing to notice here is that most Wi-Fi routers operate on two different frequency bands being 2.4GHz and 5GHz. The majority of smart appliances available on the market use 2.4GHz. Therefore, it is good to connect all of them to an access point operating on this frequency band.
Furthermore, to successfully operate with smart devices, a smartphone needs to be connected to the same kind of hotspot (2.4GHz band). If your device is unable to properly connect to the router, then the problem may be because of the strength of the Wi-Fi signal around the house. If your home has areas where your smartphone or laptop is unable to establish a wireless Internet connection, your smart appliances will most likely have the same problem. It is important to consider placing your Wi-Fi router in the central location of where you install the smart devices. If this solution still does not provide a reliable connection, you might need to consider adding a range extender, signal repeater, or simply another router to your Wi-Fi network.
