I installed nplan on yakkety but i was unable to reproduce ogra's problem neither i got the error messages i posted above - what's the software used on first boot to configure the board?
Anyhow, i manually tested the wifi driver and i was able to connect to my wlan without a hic using wpa_supplicant but while experimenting in different ways, i was able to get this stack trace: ...
