i3wm says "W: ( 68% at RouterName) 10.0.0.43". WiFi doesn't have a strong enough connection = ERR_NETWORK_CHANGED. Maybe, but I don't think that's my problem.

Since disabling those two interfaces I got
>Your connection was interrupted \ A network change was detected. \ ERR_NETWORK_CHANGED
two times so far. dmesg said:

I think the kernel is still doing something with those and I don't know what's causing it. How would I further disable those network interfaces beyond "sudo ifconfig InterfaceName down"? Run on startup:
$ cat /etc/systemd/system/veth-down.service
[Unit]
Description=Bring down veth interface
[Service]
Type=oneshot
ExecStart=/sbin/ifconfig vethfd62d19 down
RemainAfterExit=yes
[Install]
WantedBy=multi-user.target
Update: got a third ERR_NETWORK_CHANGED. Amount of "dropped", whatever that specifically means:
