All WiFi routers have a2.4 GHz band. If the 2.4 GHz and 5 GHz share the same name, you should have noproblem connecting your device you can go try to add new smart home device. If for some reason you are having trouble connecting your device to your WiFi router you can try the following. 1. Try to install the device further away from the WiFi router, outside the range of the 5Ghz (about 15 feet away) - where your phone's WiFi status bar isnot full. This way only the 2.4Ghz signal is detectable by the device. 2. You can use a mobile hotspot from a secondary mobile device toconnect the device, to do that first set the name of the hotspot and thepassword to be exactly the same as your WiFi router name and password. Turn offyour WiFi router so that the device will not try to connect to the WiFi routerinstead of the mobile hotspot, please note that all your other devices may tryto connect to the hotspot so you may need to power some of them off. Keep bothphones and your smart device close together and then connect your device usingthe hotspot. After it is connected, turn off your hotspot and turn on your mainWiFi router, the smart device will automatically connect to the main WiFi, asthey are the same name and password.
