[qubes-users] Anyone has network problems when downloading fastly?

Whenever I download a file too fast, the network stops and I have to deactivate and activate again in the tray icon. Sometimes it even displays no network (with an x). I already tried moving from 4.0.1 to 4.0.3, tried creating a brand new sys-net based on debian 10 with the latest driver (same problem persists), and also tried something about setting a memory usage on the sys-net vm, don’t remember exactly.

Also I get lots of errors downloading files, I have to retry the download many times, probably a lot of corruption.
