This sounds a bit different. Normally the problem is it can't connect and you can try again immediately or you can't connect and have to reboot. The first is because of network timeouts. The second is because of RTComm leaks a piece of data which blocks the connection from being retried. Let me try rephrasing this to see if I understand the problem. Every 15 minutes or so, The One Ring logs out and you have to log back in, and this is without any network connection changes? Or is it that it takes 15 minutes of being logged out before you can try logging in again?
