Gnome "NetworkManager could not find some"

Hello,

I get an error “NetworkManager could not find some required resources. It cannot continue”

Killing & restarting yields: "Icon nm-device-wwan missing: Icon ‘nm-device-wwan’ not present in theme’.

How do I fix this? Is NetworkManager just wireless? If so, can I turn it off permanently?

Thanks!

You don’t need it if you don’t have wireless.
