Setting up wireless on Ubuntu Server 17.04

Question

I've looked everywhere but can't find how to activate wireless networking. WLAN0 appears not to be working or activated.

Thanks

PS:Too Short?

Edit: Already tried that answer. Has not worked. The output of ifconfig is:

EDIT 2 I'm kinda an ubuntu noob. Thanks 4 ur patience. :) Output of sudo lshw -C network is

And iwconfig is

Edit 3: A start job is running for raise network interfaces (-----/5m 34s)or something like that. Mean anything to you?
