| Restarting networking on a Raspberry Pi ( debian, raspbian OS )

I had trouble restarting networking on a debian/raspbian system when the wifi disconnected.
This didn't work:
service networking restart
This didn't work either:
/etc/init.d/networking restart
But this worked:
ifdown eth0
ifup eth0
Simeple as that.
Or in a pinch:
ifdown eth0 && ifup eth0
In raspberry pi, they no longer use ifup/ifdown. They use dhcp entirely.
You can try to bring it up/down with:
ip link set dev eth0 down
ip link set dev eth0 up
You can try to restart dhcp client:
sudo systemctl restart dhcpcd
A notable tool to use for the pi: wpa_cli: LINK
