I'm trying to use the WiFi module included with the Orange Pi PC Plus, when I try connect to a WiFi network (using just iwconfig and 'ifconfig wlan0 up') it doesn't connect, resulting in a kernel panic.

Linux orangepipcplus 3.4.112-sun8i #10 SMP PREEMPT Sun Oct 23 16:06:55 CEST 2016 armv7l GNU/Linux 

Distributor ID: Debian
Description:    Debian GNU/Linux 8.6 (jessie)
Release:        8.6
Codename:       jessie 

All packages are updated. I'm also connected via Ethernet, I can disable it and try using the serial port if its necessary. 

 

I "fixed" this installing NetworkManager and using it for handling the connection. I dunno what is causing the kernel panic otherwise.
