This may help, I was doing some work with VBox - a network connected 
tuner and found on  mythbuntu 16.04 the following worked for me (I did 
try other things like wait-network-online etc).

Note I use /etc/network/interfaces file to configure static IP address 
for the  mythtv backend, rather than using a Router reservation.

To make sure backend start after network is properly configured, this 
delays mythtv backend startup.

In a terminal on the machine running mythtv backend:

sudo systemctl edit mythtv-backend.service and add the following two lines:

[Unit]
After=multi-user.target
Requires=multi-user.target


Then exit from the edit screen (it uses nano by default, so Ctrl+x, then 
y, then Return key) then either reboot the machine or do "sudo systemctl 
restart mythtv-backend.service"


If the above does not work you could try adding the following lines as 
well (this is really a last resort)

[Service]
ExecStartPre=/bin/sleep 20
