I tried to replicate the problem today on a Vero 2.
I can’t replicate it with WiFi for NFS or Samba shares.
I think it may be a timing issue. If anyone wants to try:
Edit /lib/systemd/system/connman.service (make a backup).
Replace the contents of the file with this:
[Unit]
DefaultDependencies=false
Conflicts=shutdown.target
RequiresMountsFor=/var/lib/connman
After=dbus.service network-pre.target systemd-sysusers.service
Before=network.target multi-user.target shutdown.target
Wants=network.target
[Service]
Type=dbus
BusName=net.connman
EnvironmentFile=-/etc/connman.prefs
Restart=always
RestartSec=5
ExecStart = /usr/bin/start-network
ExecStopPost = /bin/sleep 2
StandardOutput=null
[Install]
WantedBy=multi-user.target
And reboot.
