Hi Tkaiser
My apologies about my misunderstanding that knowledge about Raspbian Jessie can not apply for Armbian Jessie. That is very confusing for me, as, until now, I wondered that linux was a unique thing around the world. For sure, Torvald is not happy regarding for such much "flavors" around *bian(s).
Anyway, I just started with a fresh uSD card with the last Armbian Jessie ( from https://dl.armbian.com/orangepizero/) and configured the wifi.
Both interfaces, eth0 and wlan0 are operating normally, with dynamic IP. I can ping both.
But, if I try to fix the IP ( manual ) on eth0, using nmtui, the OPi Zero boots normally, logging as root, the eth0 shows the IP that I configured, but, it is not responding for ping. Wlan0 continues OK ( respond to ping ).
Is it necessary more setup anywhere along nmtui?
Any help will be welcome.
Thanks.
Sergio
