You need to think about that before the game for sure. Because, of course, no one will wait for you at the final table, people will be glad to steal your blinds as long,as you have been disconnected. So, if this is a freeroll game and you have weak connection, that,s ok, you can play it, but if you want to play for example tournament with 215$ buy-in, better just not to do it, until your connection problems will be fixed.
