I installed Ubuntu Server 16.04 and when asked in installation which lan interface I would like to use as default, I chose my wlan. It worked during installation.
Now that the installation finished and I booted for the first time, wlan is not working. Wasn't this supposed to work out of the box since during installation I marked my wlan to be default, and it worked?
I know someone will just post how to configure the wlan (we have some older posts like Ubuntu 14.04 Server - WiFi WPA2 Personal that helps with the configuration or ubuntu server: wifi), but that's beside the point, what's the use of asking for a default lan interface when installing if after finishing the installation I need to manually open configuration files and reconfigure my wifi?
/etc/network/interfaces
Has only
source /etc/network/interfaces.d/*
auto lo
iface lo inet loopback
Going to /etc/network/interfaces.d/ (even as root) shows nothing.
And ifconfig
lo Link encap: Local Loopback
inet addr: 127.0.0.1 Mas 255.0.0.0
Weren't these files supposed to have a configuration since I just installed Ubuntu Server?
