Can't connect to internet without using plasma

I used to use Gnome or at least, Xfce but seems like they don’t work on this OMV 3. I am only trying to use the classic windowmaker which I used to use on OMV 2014 but … I cannot connect thru drakcenter and as far as I have been reading its discontinued, Any way of using my wireless without NetworkManager? Plasma seems to be buggy enough to crank me up, plus I cannot even use the command wpa_supplicant either.

Any help?

Yes, but setting up wpa_supplicant manually is a bit tricky. You may want to use the text mode NetworkManager frontend (dialog based, fairly simple to use), nmtui
