I'm getting Disconnected out of realms and also servers sometimes

There's really nothing much to say I'm just getting disconnected out of realms and sometimes servers I thought it was my data but it's definitely not I just really hope this problem is fixed so then I can continue playing with my friends oh and sometimes I don't really get disconnected everyone just freezes and I I can move around but I can't see chats and everyone is frozen also sometimes when I get disconnected it doesn't save my progress I'm pretty sure that's normal but it pushes me really far back
