Any suggestion

Hi there ! My name's Thierry.
I've noticed a very strange problem on my new build pc which has a intel lan card on Asus z170 pro gaming motherboard... Let me tell u details.

After buying a new motherboard, processor and ram, i re-setup a fresh windows 7 64bit on 256gb ssd. well, after that i noticed qBittorrent download speed is very low, normally on my older pc, i got around 170-180 kB/s download speed, but on new pc, i'm getting only 50-60 KB/s download speed which is sometimes showing me 'stalled' and nothing download at all ufabet

so i did uninstall qBittorrent totally, cleared all the app data and re-setup qBittorrent version 3.3.7.... but the problem still persists, i did also reset my router to factory defaults, but no luck either.... i did try Bitcomet and other torrent client, they are also performing very good ! ????ufabet
And now the very strange part, i'm also running this same qBittorrent version on same internet line on my office which has that old pc, everything is fine and fresh, getting download speed around 170-190 KB/s and no problem at all....

So, my question is, what might caused this problem?

Thanks in advance.

Poor connectivity due to hostile ISPs on torrents.

Software firewall blocking qBT but not BitComet, especially if not using the same port for both during tests.

Bugs in qBT that affects speed... some confirmed, some not. Settings combinations in qBT can thoroughly sabotage it, especially due to bugs.

Making an exact matching test with multiple BitTorrent clients is very hard. Peers and Seeds come-and-go, often in minutes on smaller torrents.
