My kids and I used to play Minecraft a lot. We could be in each other's worlds while connected to WiFi at home. We're no longer able to do that after not playing for a few months. I don't know if it's because I changed my router (which I doubt). We all on the same WiFi. Or, there was a change to the game. It keeps telling me to sign into Xbox live. I don't remember if that was an option before. We don't want to play with anyone else. Just the 3 of us.
