Edit a share IP Address

I had to replace my DSL router. In the old one, I was able to assign a static ip address to every device in my home, and I was also able to edit the ip addresses range, to avoid conflicts with new devices as they turned on.

My network includes two IP TV Set top boxes (for Cable TV) connected via Ethernet which I can’t edit their ip address.

Now two of my shares have conflict ip addresses when those set top boxes are on (I have them set up with static IP) and the Media Player gives an error trying to connect to them.

Can I edit the address path in the Media Player to change only the new IP address for them, or do I have to start all over again adding the shares?

Any help would be appreciated.
