I have a System 76 laptop that is connected by ethernet cable. I started
having similar problems a while back. I sent the logs to System 76 and
they tell me my ethernet port is failing. I have a Gazelle that is not
very old. The price of a motherboard was enough to make me think about
replacing the laptop. As yet, I have not.

I've got a System 76 laptop with Pop OS 22.04 LTS (essentially Ubuntu, as far
as I can tell) installed. I've had it for almost exactly 2 years, and
networking Just Worked until this past Sunday. That morning, I noticed that
browsing to some web sites (but not others) became glacially slow, or timed out
completely. No other machines in the house (OpenSUSE, Windows) were affected. I
stepped away for a few hours, and things were back to normal, and stayed that
way, until yesterday afternoon, when the same connection slowdown/failure
happened again. Not all sites are affected. Some don't seem to be affected at
all (e.g., Wikipedia); others resolve, but very slowly (speedtest.net); others
simply time out (protonmail). Some will connect, but if they require
authentication, the authentication step times out.
I've tried clearing browser caches, and uninstalling/reinstalling browsers (Brave
& Chromium), to no avail.
I've tried shutting down systemd-resolved, because some internet reading makes
me think that it is frequently blamed for this kind of behavior, but I don't
see any difference with it shut off and an /etc/resolv.conf manually hacked
into place, assuming I did it correctly:
sudo service systemd-resolved stop
sudo systemctl disable systemd-resolved
sudo systemctl mask systemd-resolved
sudo cp resolv.conf /etc/resolv.conf # various values tried for nameserver:
8.8.8.8, 192.168.1.1 (local router address, which is what all the other
machines are using for this)
The problem is definitely confined to this one machine, so I am assuming that
there's nothing wrong with my router or other parts of my home network.
Wondering if anyone has any ideas on debugging/ what to try next. It would be a
pain to nuke the laptop and install OpenSUSE, but I have no particular love for
Ubuntu if it doesn't Just Work, and currently I'm about 60% of the way to
replacing it at the moment.
