I plugged my laptop (Ubuntu 14) to my RPi 3 (Raspbian Stretch) via ssh over an Ethernet cable.

Doing nmcli dev wifi on the laptop gives me a whole bunch of networks. Typing the same command on the R Pi gives me no network at all. I have tried ifconfig, all the interfaces (eth0, lo, wlan1) appear as expected. I have tried to switch them off and on to no avail.

I also tried :

• Edimax dongle (named wlan0)
• systemctl restart network-manager

But neither of this attempt was successful.

How to solve this please?
