ok donc un custom.sh contenant:

#!/bin/bash echo "IPv4=192.168.0.44/255.255.255.0/192.168.0.254" >> /var/lib/connman/recalbox_wifi.config echo "IPv6=off" >> /var/lib/connman/recalbox_wifi.config echo "Nameservers=192.168.0.254" >> /var/lib/connman/recalbox_wifi.config"

fonctionne parfaitement 😄
Merci!
