Max out the burst bucket size?
I don't know exactly how, but speedtest.net scales the size of the download according to the bandwidth you're using so that the test takes a fairly consistent amount of time.  A bucket size that gave you full speed on lower plans might not be big enough on smaller ones.

Just a guess.

Is there something with Canopy/Cambium Radios (PMP450) that gives reduced speed results when done behind SM's with speedtest.net <http://speedtest.net>?

I always tell customers to use www.openspeedtest.com <http://www.openspeedtest.com> for the most accurate download speeds because my customers on the 50meg plans running 450 SM's are wanting to see proof that their connection is getting that and openspeedtest.com <http://openspeedtest.com> is the only test site that will show near 50 meg tests. Go right over to speedtest.net <http://speedtest.net> and get in the 20's on the testing. This has been a problem for me for years. I just tell the customer that we do all testing on openspeedtest.com <http://openspeedtest.com> and any other test site is overloaded which is why results are slow so we do not support those other sites. Now if i plug directly into switches at towers with my laptop or am on a connection that is behind an AF5X radio then speedtest.net <http://speedtest.net> works perfectly fine and i can easily get tests of 150-200mbps.

So this appears to be isolated to Cambium 450 radios and only on certain speedtest sites. All CPE's are in bridge mode and have Mikrotik routers on customer sites. And unlimited throughput keys on the SM's. Also I must add I can do a MT Btest using TCP and still get the 50mbps test over the 450 SM so what the heck is going on with speedtest.net <http://speedtest.net> and Cambium 450 radios??????
