hehe! That is one way to do it! But I don't think Linux likes getting the power cut like that? Or is that assumption wrong?

Hi,

I use a "Odroid H4" as master and it has two network interfaces. Perfect for LinuxCNC with EtherCAT and cabled networking. However, I'm having the issue that both network interfaces shows up as if they both can connect to the internet: 


Two things annoy me:
1. Is there a way to rename these devices? The naming is kinda useless as it is and it bothers my OCD, preferably i'd call one Internet and the other EtherCAT or something like that, but i've seem to have tried everything google suggests me to rename them, without any luck...apparently not the correct one yet, ideas?
2. The top network card is the one connected to the internet...but every time the machine starts, it attempts to connect to "Internet connection" via the bottom one. These attempts causes the EtherCAT bus to reset every minute or so...to solve this i have to press "Disconnect" at the lower card and press "Internet connection" at the upper card...at every start of the system Can i somehow mark the EtherCAT card as "hands off!" for internet-stuff? And the internet is automagically connected via the upper one? First i thought "easy fix", i'll just swap cables and use it the other way around....BUT lo and behold, the problem was the exact same, but now the interfaces was just switched around...ideas?

I know this isn't "LinuxCNC and ethercat specifics", but i assume others here have had the same issues, so i hope it is ok...
