Our wifi switches only support 2.4G wifi. Now dual band wifi router is very common and most of them can set a separate name for 2.4G. You can connect your smartphone with the 2.4G first, then do wifi connection. If you cannot set a separate SSID name for 2.4G, such as google wifi router, you can take your phone to stay far enough to the wifi router until your phone indicates a 2.4G is connected on the wifi setting page. Then, pair your switch at that location.
