So I set my IP address to (say) 192.168.1.5 to access Plex on 192.168.1.5:32400/web/index.html
Some time later, perhaps a reboot, the IP address has changed and the setting has been re-set to 'Obtain an IP address automatically'.
How do I get it to 'stick' to 192.168.1.5?
I have a Spark HG630b Home Gateway.
