My PI-3B is flashed with Ubuntu 16.04 with wireless-tools and wpa_supplicant also installed.
My issue is I can't get wlan0 to be recognised by the system either dynamically (DHCP) or statically.
I am using the following config data in /etc/network/interfaces:
#iface wlan0 inet dhcp
iface wlan0 inet static
dns-nameservers 192.168.0.1, 22.214.171.124
TO ELIMINATE HARD ISSUES, On the same Pi, but with a different SD card flashed with Raspbian, wifi connection works with the following settings in /etc/network/interfaces:
iface wlan0 inet manual
So, the issue does not seem to be hardware related.
Can anyone help, please?
