I'm having issues setting up my axon S105 to connect to our wifi network.
I can ssh into unipi using ethernet cable and an offline router but I cannot figure out how to enable wifi.

unipi@S105-sn108:~$ sudo ifup wlan0 
wlan0: interface not found or invalid

I have entered wpa settings into /etc/wpa_supplicant.conf
also added wlan0 to /etc/network/interfaces

I disabled Mervis and Evok using hotspot mode as we plan to use this hardware as a node.js powered i/o controller for our customers product family.

Please, advice how to configure wifi connection / enable network interface for wlan.
Do I need to install drivers etc.? (I have no internet connection for the ethernet port)

unipi@S105-sn108:~$ sudo lsmod
