To do it proper systemd way, you should do the following:

# directory name is crucial
mkdir /etc/systemd/system/minissdpd.service.d
# file name is not important
cat > /etc/systemd/system/minissdpd.service.d/override.conf << EOF
[Unit]
After=sys-subsystem-net-devices-enp7s0.device sys-subsystem-net-devices-wlp6s0.device
Requires=sys-subsystem-net-devices-enp7s0.device sys-subsystem-net-devices-wlp6s0.device
EOF

systemctl daemon-reload

Just to be free of the formatting errors, you should create one directory,
and add three lines to one file inside it.
