Not to duplicate prior discussions but it is supposed to vary. Every time you run the test plus as you change machines.
This always results in folk asking and if you haven't read prior discussions you may feel shortchanged.
So, here at work, it "felt" like our internet speeds are not up to what they're advertised to be. We have AT&T Elite, which advertises 3 mbps to 6 mbps.
So, I tried FOUR different internet bandwidth test sites, and got 4 different results: AT&T Speed test gave me 3-4 mbps (download times), CNET gave me .7 mbps (710 kbps), DSL Reports gave me .65 mbps (650 kbps), and BandwidthPlace gave me 1.5-2 mbps. I tried each a few times on two different computers, both my laptop (via wireless router) and desktop (via ethernet). Obviously, a HUGE difference in results, so I have no clue who to believe. Any ideas/suggestions?
