The MBs downloaded at the time you see are not accurate because sometimes a 100mb file downloaded at 1P.M can be added to the 3 P.M files rather than 1. It's normal, always happens with me.kfc wroteI just did a speed test and got the following horrible results:
http://www.speedtest.net/my-result/3599190027
On testmy.net , speed was 32 kb/s
I tried to download a file without internet download manager and speed was around 30 kb/s
I tried to download a 49 MB file without internet download manager and speed was around 90 kb/s (download finish in less than 9 minutes)
Last, my account on IDM website showed that when my internet download manager queue was running non- stop 15 mintes ago, i downloaded 252 MB in 32 min (average speed: 131 kb/s)
Any explanation?
As for the speedtest, my speed is as yours I don't know why, I'll be calling them after a while to see what's the problem.
