I want to set a static IP for a Jetson Nano in my local network. What I've tried:

-- Changing the DHCP on the router.

-- editing /etc/network/interfaces with the following:

auto eth0
iface eth0 inet static
  address 192.168.1.80
  netmask 255.255.255.0
  gateway 192.168.1.1

Both this options doesn't seem to work.

It seems the Jetson Nano has an underlying configuration for the network interface of the board.

1) edit /etc/default/networking

sudo vi /etc/default/networking

and set the parameter CONFIGURE_INTERFACES=no

# Set to 'no' to skip interfaces configuration on boot
CONFIGURE_INTERFACES=no

2) Now then the settings in /etc/network/interfaces will work

sudo vi /etc/network/interfaces

auto eth0
iface eth0 inet static
  address 192.168.1.80
  netmask 255.255.255.0
  gateway 192.168.1.1

3) Reboot the board

TLDR ;

Use nmcli con mod [id] and nmcli con [down up] [id] as root.

eg:

nmcli con show 
nmcli con mod "Wired connection 1" \
  ipv4.addresses "192.168.8.70/24" \
  ipv4.gateway "192.168.8.1" \
  ipv4.dns "8.8.8.8 1.1.1.1" \
  ipv4.dns-search "8.8.4.4" \
  ipv4.method "manual"

(nmcli con down id "Wired connection 1" && nmcli con up id "Wired connection 1")& # or reboot device

Recent Jetsons nano use linux network-manager to manage network interfaces. you have to, either use the UI to modify the settings or use cli as below :

  1. show network connections with : nmcli con show

nmcli con show

  1. Edit or Modify the wired network or your preferred interface with
sudo nmcli con mod "Wired connection 1" \
  ipv4.addresses "192.168.8.70/24" \
  ipv4.gateway "192.168.8.1" \
  ipv4.dns "8.8.8.8 1.1.1.1" \
  ipv4.dns-search "8.8.4.4" \
  ipv4.method "manual"

Edit IPs as suits you and

  1. Down/Up connection or reboot your jetson with :
(nmcli con down id "Wired connection 1" && nmcli con up id "Wired connection 1")&

or just reboot

after that you'll lose access to it and with another terminal you can ping and access your jetson again.
