Hi everyone, I'm trying to enable the wifi connection on Quad / Dual UDOO boards using UDOObuntu 2.1.4. Unfortunately both the Quads and Dual UDOOs refuse to work with this release in my case. I tried different boards, swapped wifi modules ... I have access to multipe Quad / Dual boards. I can see them working with UDOObuntu v1.1 Don't think it's a hw issue here. Here are some of the details, let me know if more info is needed, Thanks, George Code: Linux udoo 3.14.56-udooqdl-02044-gddaad11 #3 SMP PREEMPT Tue Dec 6 16:26:55 UTC 2016 armv7l armv7l armv7l GNU/Linux iwconfig reports "no wireless extensions" Code: root@udoo:~# iwconfig wlan0 no wireless extensions. lo no wireless extensions. eth0 no wireless extensions.

Wifi works for me on 14.04 and 16.04, I cant understand, maybe have you a custom kernel? But I bet for a corrupt .img
