this problem is one of those elusive nasty ones. there's no one reason
why it would happen.
as you suggested, yes, DHCP can very well be the problem sometimes, if
the network fails to receive an IP address from the access point, NM
disconnects it. you can try setting up manual IPs, and connect. if it
stays connected, then try out the network. many times, DHCP wouldnt be
working not due to a configuration error, but rather because the
interface isnt receiving packets due to a driver problem.
some people report that wpa_supplicant is the culprit, i suggest you try
this command in a terminal:
ps -Af | grep wpa_supplicant
and see if more than one instance of this program are running. if just
one, keep it, if more, kill them all, then start the program again by:
sudo /sbin/wpa_supplicant -u -s
let's just test these 2 theories for now, and we'll see what happens :)
