First, make sure you’re phone is connected to a 2.4Ghz network. Your smartphone must be connected to a 2.4Ghz Wi-Fi frequency during the device set up. In some cases, you may need to set up a dedicated guest network that is 2.4Ghz. You will not be able to set up the devices using a 5Ghz Wi-Fi network. If your smartphone is already on the right Wi-Fi frequency, make sure that your phone is not using a VPN app in the background.
