Sorry for the delay.  I now get the following backtrace when running enwc-setup:

Debugger entered--Lisp error: (dbus-error "No device found for the requested 
iface.")

(run-at-time t enwc-auto-scan-interval 'enwc-scan t)))) (setq enwc--setup-done 
t))
  enwc-setup()

I get a similar message for M-x enwc: 'dbus-call-method: D-Bus error: "No 
device found for the requested iface."'.

I used this set-up code:

  (add-to-list 'load-path "~/.emacs.d/lisp/enwc/") ;; local hg clone
  (require 'enwc nil t)
  (setq enwc-default-backend 'nm)

Looking more at the backtrace, I gathered that I needed this:

(setq enwc-wired-device "enp0s25")
(setq enwc-wireless-device "wlp5s0")

With this added scanning worked: I got a list of wireless networks!

Some small requests: Instead of throwing and error, could enwc automatically 
figure out (possibly by prompting me) what my wired and wireless interfaces 
are?  Also: sorting the list of networks by clicking a header should ideally 
not scroll it (currently, sorting by e.g. Essid will sometimes scroll all but 
two or three networks out of the screen).

Thanks!
Clément.
