í cant manage my devices on the t-mobile or t-life app for the internet.

I have had T-Mobile home internet for about 2 years now. When I log into the T-Mobile app or the t-Life app I am supposed to be able to manage all my devices that are connected to my home internet but I cannot. It shows that I am connected to the Wi-Fi but it says I have no active devices when I know I do. I have a good signal but I am constantly being kicked off and losing my connection. But even when I do have a good signal and it shows that I'm connected it's still showing me that I have no devices
