Device tracker xiaomi router

Hi my name is David and I am new here.
I am using ‘device_tracker’ for Xiaomi Router 3g. This router is behind the internet service provider’s router and in AP mode with a 2.4GHz Wifi network and another 5GHz Wifi network in only one “ssid”. When ‘Home assistant’ creates the file ‘known_devices’ it only shows devices connected to the 2.4GHz Wifi network. Why is this happening?

This is my configuration:

device_tracker
-platform: xiaomi
host: 192.168.X.XX
password: XXXXXXXXXX

Thank you in advance. Regards

Hi. No one knows why this happens?
