Download speed and stalled downloads

[dimension7]

Hi.
Let me first sa that I am new to Qbittorrent so maybe my problem can be solved very easily.
First of all I cant understand why my download speed only lies around 40 kib/s - 500 kib/s. My internet speed is very high and I think I should be lying around 1000 kib/s - 2000 kib/s

Second of all I can only have one download running at a time. When I start 3 downloads, the first starts downloading but the other two is stalled.

I have tried looking in the "options" tab, and I am wondering if anyone knows which preferences I can check/uncheck to maybe solve my problems.

thx

Set your options as in the pics below. But if there is no enough seeders with good upload speed - you can't reach your max download speed. Also try a different port for incoming connections.

You may also want to set a max upload speed, according to your connections max upload speed, but less than 100% of it...

I also only get 3,8 MiB/s with qBT whereas I get 4,3+ MB/s with uTorrent. The difference may come from the fact that qBT for some reason really uses mebibytes instead of megabytes. In that case I'd like an option to use megabytes like everything else.

Im having the same problem. It gets stall way to often. Is there a log or something i can check? Any tips?
