Raspberry Pi 3 – Change from dhcpcd to NetworkManager configuration

Disable the following service for dhcpcd:

sudo update-rc.d dhcpcd disable

Empty the file “interfaces” in:

sudo nano /etc/network/interfaces

Install NetworkManager:

sudo apt-get install network-manager

Enable NetworkManager:

Edit the /etc/NetworkManager/NetworkManager.conf file

sudo nano /etc/NetworkManager/NetworkManager.conf

make sure: managed=true

[ifupdown]
managed=true

Enable Ethernet and wifi examples

Wifi: (static not dhcp)

Add:

sudo nmcli -p connection add type wifi ifname wlan0 ssid “WIFI SSID”

 

Modify:

sudo nmcli con mod wifi-wlan0 ipv4.method manual ipv4.addresses  “192.168.88.70/24” ipv4.gateway “192.168.88.1” ipv4.dns “192.168.88.1” wifi-sec.key-mgmt wpa-psk wifi-sec.psk PresharedKeyTypeItHere

Ethernet :(static not dhcp)

sudo nmcli -p connection show

sudo nmcli con mod “Wired connection 1” ipv4.method manual ipv4.addresses “192.168.88.80/24” ipv4.gateway “192.168.88.1” ipv4.dns “192.168.88.1”

 

Show some attributes:

sudo nmcli -p connection show “wifi-wlan0”
