Another datapoint: journalctl returned this during a drop: ep 03 11:18:34 localhost.localdomain systemd-resolved[1144]: Using degraded feature set UDP instead of UDP+EDNS0 for DNS server XXX,.XXX.XX.XXX. Sep 03 11:18:45 localhost.localdomain systemd-resolved[1144]: Using degraded feature set TCP instead of UDP for DNS server XXX.XXX.XX.XXX.

Possibly some more info -- I'm running journalctl -ef, and when it goes down, I see entries like: Sep 03 10:50:39 localhost.localdomain NetworkManager[1237]: <info> [1630684239.5911] policy: set-hostname: current hostname was changed outside NetworkManager: 'localhost.localdomain'

Last I used unbuntu in coroporate network, lease time was in days, maybe configure host for more frequent renewal (I can't even point you to the right direction) ? | |

I don't have a syslog, but grep-ing for eno1 (my ethernet interface) in messages returns a lot of entries. I'll need to sift through them more carefully, but I wonder if something like Sep 1 10:41:11 localhost NetworkManager[1285]: <info> [1630510871.4829] dhcp4 (eno1): option dhcp_lease_time => '3600' could be the culprit.

try /var/log/syslog and /var/log/messages. is authentication needed to access network ? (wasn't able to see it on your lshw extract)
