I have an MSI laptop with Ubuntu 22.04.2 LTS Wayland installed, that I've used for years.
The last few weeks, I connected to some new guest wifi networks, one of which I've revisited periodically. I noticed a few days ago, starting after sleeping (suspending) my laptop, and then resuming at my main network location, that now whenever my laptop is plugged in and charging, there is significant packet loss (pings between 30%-75% packet loss) and trouble connecting to the known wifi network. This now happens at my main, protected wifi network also.
The dependent variable is whether the laptop is plugged in and charging. I've updated it (when on battery power) and have rebooted, shut it down, and resumed it multiple times and the issue has not gone away.
Sometimes if I boot up plugged in or already connect and then plug the laptop in, it will work for a minute or so then start dropping packets.
If I unplug the laptop, the network returns to "normal" functioning nearly immediately .
Here is an example ping result with this issue, when the laptop is plugged in:
$ ping 1.1.1.3

This time it was actually more consistent than it usually is; usually the loss is more sparse and packets received or less grouped.
A perfect ping example when not plugged in / running on battery power:

The laptop has had battery issues and sometimes issues resuming from an automatic suspend for some time, but this network issue is completely new.
Does anyone have an idea how I would go about fixing this, and what the issue might be ?
Edit:
Output of sudo journalctl --follow at time of issue, when running pings:
