Thanks, Steve, that's what I usually end-up doing, though it's a pain in the butt. I'm just a Google video with the same effect - Connection Status monitor is fluctuating between 18Mbps and 24 Mbps yet the video is running in stits and farts. I DO have AVG 7.5 (paid for) operating. I just wish I could understand more about downloading speeds and strengths.
My daughter-in-law installed Ethereal onto my computer, but I haven't a clue what to do with it.
