It sounds like you are having router or connection issues in most of the cases you described. As far as having the crown goes that means you're the boss and pick all the options. You'll get kicked if you pick options that other people don't like or if you sit there and don't pick anything at all.
If you're the crown most the time your main issue may be either hitting the ready button too soon (which wouldn't allow many people in the game) or not hitting it soon enough (which would cause many people to get bored and leave)
It all boils down to you not using the interface (although it is difficult to understand) correctly. I would explain to you how to use it properly but I don't feel like typing it out. Keep trying and you'll get the hang of it. Good Luck.
