I reported another weird discovery in
https://bugzilla.kernel.org/show_bug.cgi?id=213377#c13.
Booted without any additional kernel parameters, I can "fix" the
download speed if I plug in an USB stick. That would explain why the
installation works in the first place, because I booted ubuntu live
That would be strange. After systemctl hibernate, the system went into
hibernation, I got the resume message while booting and the system state
was restored just as before hibernation. The system was not just
suspended. I had to go through grub and the hard disk decryption
password.

The current kernel was started using the kernel parameter, speeds where
fine. I did hibernate, restart the laptop, and now network was broken.
I did another reboot afterwards, booting clean with kernel parameter but
now network connectivity is still broken.
I am not able to spot the system
I just tested this, but after hibernation, the same network errors occur
as before.
