Switching between UDP and TCP isn't going to have much impact on your problem if it is a function of a lower network layer. In a case where you have a questionable connection, TCP is really what you want, because UDP has a habit of saying "oh, can't get this packet to ya, sorry, see ya later, drop packet". In other words, UDP is more a hope for the best sort of situation, whereas TCP has built in retranmission, error checking, etc. Again, I'm not sure what exactly you are trying to accomplish with this idea?
