Client stop downloading or limits speed!?

[mosteanuv]

There is something I don't know about this client, I looked everywhere in the settings but can t find the answer!

The client stoppes downloading or maxes to 5-6MB (normally I have 80-100MB). The trackers show working but downloads aren t starting!

Other clients work just fine.

I tried everything the obvious: re installed, changed port, firewall, restarted, different trackers etc

If I:
1)Exit Qbit
2)Go to "%appdata%" dir and delete qBittorrent.ini and qBittorrent-data.ini
3)Start Qbit
it works great again. But i have to do it every few hours! Anybody know why?

Just a test;

Can you set your cache manually to 128MB within the advanced settings and see how it performs?
