qBittorrent official forums

I used to be able to set the max number of connections as low as current number of connected peers with DL over 1KB to drop the idle ones and very low rate ones to make room for more, but now when I do that I sometimes loose good seeders! For example just now I was connected to about 100, 15 of which were uploading to me so I set max connects at 15 and then it dropped all but 3 of them. Tried updating to the latest version and it doesn't help. I've had slow speeds and congestions on this wifi when connecting to hundreds at once which is why I do this.

Wifi is part of the reason -- you will randomly, briefly disconnect from potentially anything no matter how good a peer or seed is. A particularly bad moment on wifi can cause everything to disconnect.

uTorrent (and some other BT clients, like maybe Vuze/BiglyBT) will drop idle peers/seeds if near max number of connections either globally or per torrent, but I don't know if qBitTorrent has that ability.
Even if qBT does have that ability, it's probably in libtorrent with no option/s in qBT to change the behavior.


"I set max connects at 15"

Did you mean max half open connections, global max connections, max connections per torrent, max upload slots per torrent?

The connections tab, there was only 1 torrent running and I used the max connections per torrent box. I did this same exact thing before with same networking setup and it worked fine a couple months back. I'd put it around 100 to go out and sample whats out there, then see how many fast ones I had and then set the number to that or slightly higher to DC from everyone else, repeat if needed until desired speed reached. Supposedly qbt does this on its own but in my experience it can hang onto a 0 dl 0 up peer for quite a while like longer than I wanted to stare at it, longer than 5-15 minutes etc.

I get what you're saying about wifi but I am confident that this isn't a coincidence, plus I did not see any time that I randomly DC from all or many peers. Literally I'd be connected to about 15 that were currently uploading to me, set the connection # to 15 then it kicked all but 3. Similar effect multiple times I tried this, which is new and random behavior compared to before with same version same pc/network.
