Just ran few "highly regarded" download speed tests, and each gave me different results: from 2.8 Mbps to 6.8 Mbps, to 12.3 Mbps to 20.6 Mbps.
Best Internet Speed Tests | Digital Trends

then tried AT&T Speed Test - Check Your Internet Speed, Speakeasy Speed Test, Internet Speed Test - CNET and Speedtest.net by Ookla - The Global Broadband Speed Test and all gave me download speed in range 19.7- 21.6 Mbps. I pay for 20 Mbps.

So, what's going on with those "recommended" speed test websites? They seems to be totally unreliable.

I've noted the same thing, but have figured that the NOC for my satellite feed is fetching and responding before it even gets to my computer except for the latency test. (Satellite feeds are crunched to save bandwidth for the satellite provider.) Another aspect is that the number of hops can change results, as can the speed of the individual hops of the packets. I doubt that any one speed test is meaningful. It is the aggregate results from a few that provide a useful guide.

It also depends on the server you are testing against, like with speedtest.net, how it gives you different places to choose from before it starts the test, if the place you are testing against is under heavy load, it won't give you the speeds you should be seeing. Test at a few locations that are still close to you and get the average.

Truth be told I usually only run speed tests if my internet seems to be moving slow.

When you make a request from a web server, the path sort of looks like this:

You--------ISP-------Internet------server's ISP------web server

That red part is what you're paying for. And what's between the two ISP's can comprise of multiple hops. Each of those hops can slow down the request/response. And as other's have indicated, there are various factors (distance, load, congestion, etc.). Even at just your own end, how you connect to your LAN and what's going on your own network can impact those numbers as well.

As they say - there's bandwidth, and there's throughput.

Ha! Thank you all for the explanation. It makes sense. I will not bother with that anymore.
And yes, I run speed test when I notice that my computer is really slow.

Run it while connected wireless. That will get your attention.

The speed tests are going to vary depending on where you are in relation to where the test server/site is located. Since these test sites have different locations your results are going to vary from site to site.

Yeah, I was aware of that, but not that the speed test results would be between 2.8 and 21.6 Mbps.

Actually having a high end router will resolve that. My worst case scenario is about 20% loss at my furthest point in wireless vs wired.

That is a drastic difference. Most of the times I have ran those tests the difference at most was double. I wouldn't think you would see that much of a difference between the high end and low end.
