I can't play at the same address

When trying to play with my wife at our house, I get "Could not connect to the world", it only lets me enter the world when I am using mobile data, when I use the wifi in our house, that is when it does not let me access to the world. She has an Android and I have an iPhone, when playing with both Androids, everything works perfectly. We have tried in different addresses, and the problem persists.
