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?**
