I've found that while a torrent is at a seeder/leecher ratio of 1 to any other number (say 1/50 or 1/100) you will pick up lots of leechers to upload to before you've finished getting the file yourself. Once the ratio tips (the moment when more than one person has the entire file) that's when the seeding drastically declines. That's been my experience. It's important to note, that while the uploading may decline, it's still a good idea to seed for as long as possible even if no one is connected to your client (you'll still get bonus points based on time seeding).

As far as piratebay seeming to have more leechers for you to seed a file to, those and other open access trackers can have thousands of leechers across multiple trackers, whereas the most you'd see for a file here on our single tracker would be less than 200 per file, so that accounts for your lessened upload activity here as opposed to there.

I don't think your router has anything to do with it.

Hello,

I want to upload some things to try and fix my ratio and I would like to use my old MacBook instead of my windows gaming pc. Is this possible? I also need to know what's wrong with my router cause most of the time my torrent client never uploads after I download stuff. I have left torrents running for hours after it finished downloading and it uploaded nothing (unless it's a freeleech item, but they upload very slow), but when I download for other sites like thepiratebay or rarbg I can upload with my no issues at fast speeds. Can someone help me with this problem?

Router: Arris Surfboard SBG6950AC2
Internet Speed: 1GB Download, 100 MB Upload
Torrent Client: qBitorrent (Windows 11 and macOS High Sierra)

Absolutely - somewhere on the forum is a turorial for qBittorrent one of the admins wrote - it works for Windows, Mac, and even Linux.

I'll look and post a link here if I can find it...
