The full WPA connection timeout for NM is about 30 seconds.  That's
usually plenty of time for the supplicant to scan, find the AP, initiate
the 4-way handshake, and finish it, *especially* for WPA.  I'm very
curious about why your setup is taking longer.  You can put the option
"-dddt" into
your /usr/share/dbus-1/system-services/fi.epitest.hostap.WPASupplicant.service file at teh end of the "Exec=" line, then 'killall -TERM wpa_supplicant', then attempt to reproduce the issue, and mail me /var/log/wpa_supplicant.log so we can see what's going on.
