Not at all, but I don't have a donkey turning a wheel powering my router either. If my connection craps out. I leave the party, I don't continually hold my party back like an ass because I can't keep a stable connection. If you've got a crap connection it's unlikely it'll be cleared up before your 30 minute penalty goes away anyway. Suck it up, realize you aren't the only person in your group and leave, so that the people with stable connections can finish the dungeon in an efficient and problem free manner.
