cc6 ubuntu 16.04 wifi module does not turn on.

I have connectcore 6 and trying to port ubuntu 16.04 using the following link below
https://eewiki.net/display/linuxonarm/ConnectCore+6+SBC

I am trying to get the wifi module ON but have no luck.
I also compiled kernel to have ath9k drivers but no luck.
tried all sudo commands and getting error “failed to bring up wlan0”

see how it works with stock digi images, you might need to copy their driver and/or microcode.
