I've never dueled, but now i kinda want to start it. My Internet gives me alot of Problem in Various Places but now my Question is : How does pinging in Duels get handled?

Sometimes my internet shuts off... sometimes my Repeater shuts off and i dont get a signal ... sometimes my internet goes down to 86k/bits and thats not enough for the Server so i ping, and that would be fatal in a duel wouldn't it?

Do i have to make that out before the Duel? or do i just continue dueling after thee ping? is there a Time Limit to reconnect after pinging?
