Hello My friends..!
so i am struggling to understand this issue, i will be very crateful if any one can help in explaing how that happen..
i have two ISP each of one is 20M internet speed so i setup a loadbalancing Rule inside My RB1100 and it work well But the question that came to my mind is like this. when i apply internet speed test from my PC that connected to this router i get a speed of 40M while when ever i downloaded any file the speed keep the same yet it is separated between the two ISP..!
so how does this happen..?
i mean why speed test tool combined the two internet connection..? what is the magic that they do that file download cannot..?
If you are reffering to Ookla Speedtest, doesn’t it use multiple connections by default?
Change it to single and see
Wow, I want that router maybe lays golden eggs too. 
Next magic: why torrent download can reach 40M
