Your system is seeing wifi, wlp3s0 is using the Intel 3160 wifi driver iwlwifi.
You even tried to connect to a wifi access point and got an error in your wall of text.
Did you try putting the interface up first, then running the iwconfig command?

This link suggests changing the mode of the device if the above does not work, https://unix.stackexchange.com/quest...-not-permitted

Maybe try a text tool like wicd-cli to connect to wifi from the command line?
