When I'm connected to the internet through my wireless router, I'm seeing numerous connections being made. They seem to come in waves and last only seconds and then disappear. This happens when I'm not running any software, at least none that should be active or that I'm using, like a browser or word processor. These connections appear to be from locations in Israel, France, UK, India, Luxembourg (I'm in Cyprus). Some, but not all of them appear to be associated with my ISP. Does anybody know what these connections are? How can I stop them.
