If I load the page and watch the status lights for the connection in the system tray, I see the receive light flash off a couple of time. This is enough to goof up the speed. I think the calculation also rounds down when figuring out the modem connect speed. Repeat the test a few times by reloading the page and use the highest throughput number. Then multiply by 8 to get a bit rate. This will be lower than your actual connect rate due to the "dead" times when no data is being transferred. -- Rick "rickman" Collins rick.collins@XYarius.com Ignore the reply address.
