Hipad Max - WIFI not working properly

Hi, i have one Hipad MAX that i received today.
I was test the equipment and the wifi can’t stay connected for more than 1 second.
I tested 2 Radio Stations ( from diffrent providers, and it happens too at 2.4ghz and 5ghz)

So there are any way to fix it or need to send is back for repair?
Best Regards
