I tried out download speed tests and there's something I'm either missing or fishy.
Airtel & SpeedTest.net are indicating that my download speeds are at 2Mbps.
PCPitStop, DSLReports, TestMy.net are reporting that I'm at 0.2Mbps!
That's a whopping difference.
(PCPitStop, depending on the type of test, location of server, shows different results - this is probably truly representative of what can happen with others as well)
I can speculate some reasons why some of those appear faster than other, but when I tried download software (via browser, free download manager), it still remains at around 256kbps or .25Mbps.
See the results for yourself.
2Mbps speed results
0.2Mbps or ~256kbps speed results
