Well well well. I've had no disconnections since the last, (touches wood) which the date of, I forget at present, everything seems to be ok since I limited the amount of ports to be open on my PC while downloading/uploading.
So the theory of DOS attacking yourself with P2p software seems to be true.
Doing this has made no changes to the upload/download speeds and everything seems like gravy at the moment.
So here's

to the future of not being disconnected.
