Can I use 5G WiFi to connect to the camera?

Our camera currently only supports 2.4G WIFI because it can only work under 2.4G WIFI. If your router supports 5G WIFI, it may also support 2.4G WIFI. Please contact your router seller. Please tell me how to change WIFI to 2.4G. Please change your phone's WIFI to 2.4G before setting up the camera.
