#Trabajamos con el fichero /etc/network/interfaces
1. Le hacemos backup
2. Le editamos y le dejamos asi:

# interfaces(5) file used by ifup(8) and ifdown(8)
# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
source-directory /etc/network/interfaces.d

#Reiniciamos los servicios o directamente la pi.



#-------------------------------------------------
Tambien existe el metodo dhcpcd method

Leave /etc/network/interfaces at its default (as above).

Edit /etc/dhcpcd.conf as follows:-

 Here is an example which configures a static address, routes and dns.
       interface eth0
       static ip_address=10.1.1.30/24
       static routers=10.1.1.1
       static domain_name_servers=10.1.1.1

       interface wlan0
       static ip_address=10.1.1.31/24
       static routers=10.1.1.1
       static domain_name_servers=10.1.1.1
ip_address is the address and size from the command above (or another unused address on the same network),
routers is the address of your router (or gateway).
domain_name_servers is the DNS address(es) from /etc/resolv.conf.
(see man dhcpcd.conf)

There is a good article on dhcpcd at https://wiki.archlinux.org/index.php/dhcpcd The Fallback profile is an alternative to static IP
