This may help you narrow down the problem, if there is in fact something using it up. You may want to try one of the internet speed test sites (e.g., speedtest.net) to see if you're actually getting the bandwidth you think you should be getting. I had a similar problem and quickly found my DSL upstream bandwidth had dropped by a third. After some calls to the service provider I was able to get it resolved. You may also want to see if your streaming video site changed something. The trend is to upgrade to higher-bandwidth streams for the benefit of people who have fast cable modem connections, but it can lead to a lot of buffering delays for us DSL customers. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Not in the FBSD ports, not in the Ubuntu packages. I found a clue via google; it worked. The problem was that my modem/router needed to be reset to its factory defaults. iftop sometimes stalled for several moments--enough to cause streams to timeout if they did, in fact, get started. Now I can connect even to bbc4 in a couple seconds instead of a minutes. If anybody else has had trouble connected to distant sites, I suggest you check your routers. Might find that you get much better response times. --gary -- Cordula's Web. http://www.cordula.ws/ -- Gary Kline kl...@thought.org http://www.thought.org Public Service Unix The 7.97a release of Jottings: http://jottings.thought.org/index.php http://journey.thought.org ethic ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

You need to take a more methodical approach to the problem.
