Have you tried maintaining the ssh connection from a different internet connection? Assuming you have no issues it is probably related to the ISP. It would also be a good test to to try sshing to a server in another location and seeing if your connection drops but given that you are experiencing pidgin dropping as well. I would assume it's internet related. Do you have another computer you can test with?
