Issue:
Unable to set static IP from RR menu, tried to manual amend the /etc/network/interfaces but seem like after restart everything will be go back to default state, not sure is it part on the buildroot default setting

Same goes to RR menu static IP, first configure is fine to get ping from new ip, but it will go back to dhcp assign ip after restart

logs:
Let me know if any log is required to debug
