The problem sounds that your local IP changes as soon as your router gets offline, this is normal because the DHCP server in the router stops and most likely drops all current IP addresses.

In order to solve this problem and give yourself a manual IP address you can either make a reservation in your DHCP list(on the router) or change your network settings do a static one
