No wifi on remote vnc server

[makem2]

I have just setup Ubuntu 19.10 on a Raspberry Pi4 and am using tightvnc from a linux laptop to access it remotely, headless. I am able to connect via ssh, with remmina and use the internet.

The wifi icon (two arrows) is greyed out and the settings from there are also greyed out. I thought that wifi was automatically associated.
