Netatmo device not connected wit RT-AC88U

Hi guys,

I just installed my router AC88-U and the wifi signal (2,4 and 5mhz) are working perfectly. All the devices work perfect, but my home automation like netatmo weather station and blinds control did not link to the network.

I tried to connect the old router and the system connects perfectly. I think the Asus did not let connect them, does anybody know why?

thank you very much
