I got an identical 15 ms. with both Chrome and Firefox tested twice. And a ridiculous 5 ms. tested twice with IE9. That result is nonsense. That's over WiFi. I wonder if Speedtest.net is "altering" their ping times in a deal with Microsoft.
More likely just a Java error of some kind in IE9. Who knows?
If I use the Rogers test page, I get 34 ms. with Firefox and 11 ms. with IE9.
Any claim that the root of a problem is simple should be treated the same as a claim that the root of a problem is Bigfoot. Simplicity and Bigfoot are found in the real world with about the same frequency. David Wong
