My dsl tests at .52mb/s, why is actual download speed only 20kb/s?

I'm paying for about .5 mb/s that I'm not getting, I don't get it. Any help would be greatly appreciated.|||You've got to differentiate between megabits (Mbps) and megabytes (MBps). ISP's advertise in megabits so they can look better than they really are. A bit is 1/8 of a byte, and so when you're downloading in firefox/IE, and it says 20 KB/s, thats 20 kilobytes, which is 160 kilobits. Granted, that is less than 500 kilobits, but you see the issue. The best speed you could hope for is 500/8, or 62.5 KB/s.|||As a rule of thumb:





(Download speed divided by 10) minus 20 to 25% = average download speed





So the download speed of a broadband connection with 500kbps (0.5Mbps) results in:





(500 / 10) * 0.80 = 40 kBps resp. (500 / 10) * 0.75 = 37.5 kBps





I reach with my 8Mbps link a download speed of around 820kbps, it all depends on the overbooking the provider makes. If you live in a crowded area it is possible the speeds are lower, Of course it also depends on the connection of the remote server where you connect to.





It looks indeed your connection is a bit slow
