Weird. Still nothing wrong! Let's see:

cat /etc/NetworkManager/NetworkManager.conf
cat /etc/network/interfaces

Also, does it scan?

sudo iwlist wlp2s0 scan

We needn't see the whole list, just tell us if it does or does not see networks.

When you click the Network Manager icon, do you see your network? What happens when you click on it and try to connect? Are you challenged for a password? Or what happens?
