You might want to consider putting up a speedtest server internal to your network. I know there is a fee but well worth it I believe. You will still need to take the results with a grain a salt but you will have the best results as well.

One thing that I was able to deduce was that one of the radios along the path had Ethernet auto negotiate turned on. I turned it off and the TCP speeds went way up. It seems that UDP was not affected by this setting while TCP was. Thanks again! Lorell -----Original Message----- From: Justin M.

I am having some speedtest results that are difficult to interpret.
Some of my customers have begun complaining that they are not getting the proper speeds. They are using speedtest.net and/or speakeasy.net to test the results.
Take the speedtest results with a grain of salt. Once traffic leaves your network, you no longer have (much) control over how packets flow across the 'rest of the internet'. Did the customers report when the issue started? Are they seeing other performance problems (latency/jitter/packet loss)? Are you sure no internal links/routers are being saturated, even for brief periods of time? jms
