I have RPi3 + Amp+ and the Volumio image from the HiFiBerry installer (kernel version 4.1.19-v7+ #858 ). When connected by ethernet system works perfectly. However I can't get the wifi working as there is no wlan0 interface

iwlist wlan0 scan
wlan0 Interface doesn't support scanning.
I have updated as follows
Using the HiFiBerry Raspbian SD image the Wifi works perfectly.
I can't find anything relevant on the web. Any suggestions as how to resolve this problem please.
