I know this one has been beaten to death, but I couldn't find quite what I am looking for on the other threads. I initially had troubles a couple days ago until I read that changing the listening port might work, so I did that, and it worked!! Until I woke up this morning only to realize it no longer works. The only thing that has changed from the last time it worked is I am now in a new house. Same provider same service, new location. Why isn't it working?
