Somewhat related to this question. I have a BeagleBone Black running Debian and am trying to use its ethernet port for internet (rather than USB sharing as is typical when getting it up and running).
However, I can't seem to get it to connect to the internet properly. For reference, I am connecting it to the network at work, and am behind a firewall. It seems to be assigned an incorrect IP address, based on the other devices on my network. It is inaccessible via SSH or ping to the 10. address, however I can still SSH based on the USB static IP address.
I'm not exactly sure what the real issue is here, if I simply can't access it because its on another subnet at work, or if there is some conflict between the USB static IP and the DHCP-assigned IP for eth0, or something else.
If anybody can suggest troubleshooting steps, or if this is an easy fix, I'd appreciate it!

The last point is that eth0 is on the 10. network, however my other devices that are plugged in are all on the 141. network. I'm not sure if this is because its contacting the wrong DHCP server, or if somehow that particular plug is looking to the wrong spot.
Edit: when I try to add a route to what I imagine is the 'correct' gateway, I see the following:
root@beaglebone:~# /sbin/route add default gw 141.210.154.1 eth0
SIOCADDRT: Network is unreachable
