Loss of data packets is an issue. Some connections thru some ISP providers or due to line or device equipment may all play a part in unreliable relay of info. Fine for browsing but if you're uploading or downloading large files then any data loss (packet loss) can mean a corrupt file. There are sites where you can test to see the reliability of your line. eg: http://www.broadbandreports.com/tools & Line Packet Loss Testing is the test.
