NM also doesn't do anything materially different from wicd; NM
constructs a configuration for wpa_supplicant and sends it to the
supplicant.  Which is also what wicd does.  NM dumps the configuration
it sends to /var/log/messages or /var/log/daemon.log depending on your
distro (in your case, likely /var/log/daemon.log) so you can see exactly
what NM is telling the supplicant to do.  Supplicant debug logs would
also be useful, there's more details about that here:
