Local network configuration JetPack 5.*

Robotics & Edge Computing Jetson & Embedded Systems Jetson Xavier NX

I’m trying to configure NVIDIA Jetson Xavier NX Developer Kit with my local network. I have a couple of devices attached to my network and I would like to communicate with them using dedicated subnet e.g 192.168.28.*.

Previously when I had a JetPack in 4.* version network configuration works out of the box. When I updated JetPack on the machine, using ssh, after reboot local network stoped working. When I reinstalled JetPack with newest version 5.* network still does not work. Of course I can connect with USB and network is working in 192.168.55* subnet but I would like to drop USB connection and use ethernet only.

I was trying to configure local network using nmcli tool bu I had no luck. Out of the box “Wired connection 1” is disabled. When I try to enable this connection I get a message that there was an error I need to inspect logs. Logs:

Some DHCP problems? On my local laptop I have setup DHCP server to assign addresses from range 192.168.28.100 - 192.168.28.200.

When I’m changing “Wired connection 1” to use static IP I can enable it but this IP is not accessible from other devices. Only when I set static IP to USB subnet e.g. 192.168.55.120 I can access machine. Of course when I unplug USB I no longer can access machine.

Hi,
Generally when we connect Jetson device to LAN, it is assigned IP address automatically. Please try this and see if it works.

For assigning static IP address, you may try this:

Incidentally, if you run “ifconfig” (or on newer systems, “ip -s addr show”) prior to plugging in the network cable, you can see a list of byte counts in a number of categories, including RX and TX bytes, plus a number of errors. Upon plugin there should be an increase in bytes for TX if a DHCP request is sent out, and some new bytes on RX if DHCP was sent back. Other error counts are also of interest. Perhaps the DHCP server inside of the router is not responding (one reason would be security).
