relevant log from journalctl

I don't know what to say but I'll try to describe my reproducible experience. I work everyday using the browser, zoom, slack, telegram, spotify, etc. During the work the wifi is great and I experience no problems with it.

When I turn on a torrent, everything is slow. Speeds of the torrents change a lot and the mean are like 1mbps (when it should be way more). This situation persists and it's mildly infuriating, and then after a few minutes the connection drops entirely. When it drops, I can just restart the NetworkManager service and it gets up again. If I keep the torrent, it drops again in the same way.

Looking at the `journalctl -f` log something grabbed my attention. A crash on the driver that I'm feeling cannot be unrelated (attached on this post).

I don't know how else I can help. I can reproduce it and log anything you folks need or run any tests or anything. Sorry if this is the wrong place or the wrong way to submit this issue!

PS: My adapter is an Intel 9260 connected via PCIe 1x.
